ASTM Committee D01 reports on June 2005 subcommittee activities.

ASTM Committee D01 on Paint and Related Coatings, Materials and Applications held its 2005 Summer Meetings at the Pittsburgh Hilton Hotel, Pittsburgh, PA over the period June 19-22, 2005.

Highlights

Subcommittee D01.21, Analysis of Whole Paints and Paint Materials, continues to work on a number of methods and practices of importance to the coatings industry and the users of its products. Projects include development of a retention time (retention index) library for use in the measurement of HAPS using a GC, work on improvement on methods for GC analysis of specific volatile components and headspace analysis for low VOC levels in waterborne products. A new task group is working on a method for water in paints using a calcium hydride test kit. D01.23, Physical Properties of Applied Paint Films, has completed a new method for measuring dry film thickness. After a lapse of several years, work has begun again on a practice for measuring contact angles on coatings and substrates. D01.25, Evaluation of Weathering Effects, is revising D7087, an imaging method to measure rust creepage. A recent round of interlaboratory testing has produced improved precision data. D01.34, Naval Stores, continues to show progress on a more rapid method for the measurement of the neutral content of tall oil fractions without the use of diethyl ether. D01.35, Solvents, Plasticizers and Chemical Intermediates, has revised and balloted a large number of methods and specifications. D01.37, Ink Vehicles is working on a new practice for preparing oil-based resin solutions that includes the use of the Thermotronic 11 automated varnish cooker. As usual, D01.46, Industrial Protective Coatings, had a very productive series of meetings. Methods for metal surface preparation, measurement of metal surface roughness and profile, solvent resistance of coatings, adhesion by pull-off, graffiti resistance of coatings and analysis of soluble salts from steel substrates all were discussed. D01.47, Masonry Treatments, discussed water vapor transmission and anti-graffiti coatings. D01.56, Printing Inks, heard reports on ink mileage and VOC of radiation cure inks. D01.57, Artists' Paints and Related Materials, discussed lightfastness, physical properties and toxicity, D01.61, Paint Application Tools, received copies of the new "Standard Guide for Application and Evaluation of Brush and Roller Applied Paint Films."

DIVISION 1 ADMINISTRATION

D01.06, International Coordination and US TAG to ISO/TC35

T. Sliva, Chair

ISO/TC 35 has a new Chair, David Maggs of Akzo Nobel. ISO/TC 35/SC 9 also has a new Chair, David Heath of BSI. ASTM D01 members 1. Russell and O. Cordo attended the ISO/TC 35 meetings in London in early June and both reported their impressions. It appears that there are no technical barriers to the ASTM D01-ISO/TC 35 Memorandum of Understanding working, but politically, it is a big problem. On the recommendation of D01.31 on Pigments, D01 is withdrawing from the ISO SC2 Pigment Group because nothing is going on there. That will save us $490 per year. TC 35/SC 9 has been selected to participate in a trial of electronic E-balloting for use by technical subcommittees.

D01. 15, Lectures and Symposia 

W. Golton, Chair

This subcommittee is responsible for arranging lectures at meetings and occasional symposia. The program typically is a seminar with a few speakers on a topic of interest, staged annually at the January meeting. We refer to this session as a "mini-symposium". The focus of the mini-symposium on January 24, 2006 will be on statistics: its use in the development of standards, trends in ASTM and future impact on standards development. Robert Morrison, Chair of D01.20, the Quality and Statistics Subcommittee, will help organize the mini-symposium.

D01.16, Terminology

J. Bryson, Chair

The purpose of this subcommittee is to maintain Terminology Standard D 16 by developing and updating coatings related definitions. C. Serio noted that Subcommittee D01.61 is considering having its own terminology standard, rather than including paint applicator terms in D 16. The following definitions will soon be balloted for inclusion in D 16:

tint, v -- to confer a small level of color to a coating formulation.

paint, n -- general, a pigmented (liquid or paste) coating material, or a coating resulting from the application of such a material.

drying oil, n -- an oil that, when applied as a thin coating, becomes a strong, flexible, cured film because of reaction with atmospheric oxygen.

DISCUSSION: Most drying oils are glycerin esters of highly unsaturated fatty acids.

crawling, n -- a defect in which a wet coating film recedes from small areas to form an uneven surface.

J. Bryson will contact technical subcommittee chairs to ask them to review the terms and definitions (in D 16) of interest to them.

D01.94, Awards and Memorials

T. Sliva, Chair

The chair announced that A. Freidenfelds would receive the Gardner Award for Task Group Chair of the Year for outstanding leadership in the development of the new method for dry film thickness. We then stood and had a moment of silence for Lon Adams, Chair of D01 on Architectural Coatings, who passed away just before the January meeting. Mr. Adams had made outstanding contributions that had resulted in numerous standards.

D01.95, Promotion

L. Pattison, Chair

A lively discussion centered on Publicity. A promotion letter had been sent out to users of EPA Method 24 (on Determination of Volatile Matter Content, etc.) and the six related ASTM methods inviting people to join D01. The basic message was "If you use these methods, you should get involved." The letter went out in late May and a few responses are coming in. We still are very interested in producing a D01 publicity pamphlet, but deciding what to put in it is more complicated than we thought. J. Driver of Arizona Instruments is ready to help, but we still have not made a decision as to what we are selling or who our targets are. We need "bullet" items for promotional documents (why ASTM is important, value of ASTM participation to a company). The discussion turned to the lack of attendance of key members at meetings, especially this one. We must somehow convince company supervisors of the value of ASTM participation and the need for their ASTM members to attend meetings.

DIVISION 20 RESEARCH

D01.21, Analysis of Whole Paints and Paint Materials

H. Fujimoto, Chair

The committee had wished to withdraw two standards, D215, "Standard Practice for the Chemical Analysis of White Linseed Oil Paints" and D4358 "Standard Test Method for Lead and Chromium in Air Particulate Filter Samples of Lead Chromate Type Pigment Dusts by Atomic Absorption Spectroscopy." The main impetus for withdrawal of D215 is the fact that this method uses a Gooch crucible lined with asbestos. ASTM would like to eliminate reference to the word "asbestos" in its standards. Also, we do not believe that anyone manufactures white linseed oil paint any longer, so this method is no longer needed. D215 will have to be reballoted, since it was balloted as a revision, instead of for withdrawal. The movement to withdraw D4358 was based on a mistaken belief that lead silicochromate pigments were no longer being used. The ballot for withdrawal received a negative, which was ruled persuasive, since the negative voter pointed out that these pigments are still in use, and that a method for analysis needs to be available.

Although there was no joint ASTM/ISO TC35 meeting held in Pittsburgh, Dr. H. Nissler, who is currently chairman of the ISO working group on determination of VOCs in paints, gave an update on recent activities in his group. These include a GC-VOC method for the "Deco Paints Directive" and developing/modifying their GC methods to be consistent with their definition of VOCs. His ISO group agreed that it would be a worthwhile idea to have an ASTM/ISO joint group to discuss issues, which would lead to closer cooperation of global activities. This could also lead to having the same definitions/methods globally, and could avoid overlapping efforts, where both groups, are working on similar methods, individually.

The group on Clarification of EPA Method 311 provides feedback to the U.S. EPA on their Method 311 for HAPS in coatings. There has been controversy about this method since it was published several years ago because it allows individual laboratories to select their own gas chromatographic methods. The group reviewed a summary of the inter-laboratory study of EPA Method 311 that had been prepared by M. Wills. The plan is to circulate the report to participants of the recent NPCA round robin for comment. Once additional comments have been received, the report will be submitted for publication in JCT COATINGSTECH. The group will also continue to seek additional input from participants and other members of ASTM D01 [Note--A copy of the full statistical analysis of the data is available for review from Task Group Chairman, R. Nelson]. The task group will continue to work with Dr. Wills on the development of a GC retention time (retention index) library to assist in the measurement of HAPs and other volatile components of coatings using a GC. The task group will also follow up with Dr. Wills on the development of a new test method for solventborne coatings by SPME/Direct GC.

The Rapid Nonvolatile Determination group discussed ballot results for WK 3882 "Standard Test Method for Rapid Determination of the Nonvolatile Content of Coatings by Loss in Weight." One negative vote centered on spelling and grammatical changes, but was found to be non-persuasive. Comments submitted on an affirmative vote regarding re-organizing the procedure were generally accepted. The task group is working with the voter to determine an optimal solution. WK 3882 will be submitted to the next concurrent subcommittee/main committee ballot.

The group on GC Analysis of Specific Volatile Components has jurisdiction over three methods, D6133, D6438, and D6886. It was reported that the reproducibility values for D6133 (acetone, 24.5%, methyl acetate, 29.3%, PCBTF, 12.4%, and t-butyl acetate, 15.6%) could probably be improved by incorporating more specific language into the procedure of the method. A draft of the method containing such language is being prepared. This will be followed by a round robin to establish new precision values. Method D6438, the SPME/GC/MS method for exempt volatile compounds, is being rewritten to include t-butyl acetate. Method D6886 was discussed in terms of its applicability for measuring the VOC content of low VOC (less than 5%) architectural coatings. In early 2005 the California Air Resources Board (CARB) signed a contract with California Polytechnic State University to conduct a three-year study to review various analytical methods for measuring VOC in architectural coatings and to develop a "comprehensive set of direct test methods for VOC analysis" that will be suitable for determining VOC content in the full range of architectural coatings. CARB's intent is to develop a single test method or set of methods that will "provide CARB, other regulatory agencies, manufacturers, and testing laboratories with unified and common methods" for testing all of the coatings types identified in the 2001 CARB Architectural Coatings Survey and "eliminate the current situation where each agency has its own set of methods, many of which are non-validated versions of those referenced in EPA Method 24 itself." A summary of CARB's survey taken from "Final Report of the 2001 Architectural Coatings Survey" was presented. The entire survey report may be found at: http://www.arb.ca.gov/coatings/arch/survey/2001/survey.htm

The group on Headspace GC Method for Low VOC Levels in Waterborne Products viewed a presentation by L. Mink on the status of the headspace VOC method. He reviewed the results of the March 2005 ballot, which included two negative votes and numerous comments. It was acknowledged that the precision of the test method was not adequate, and data were presented regarding the variability in the method. One source of variability is the specimen water content and its effects on vial pressurization. In response to the comment that the method requires sophisticated equipment, the use of which should be avoided in ASTM methods, it was noted that headspace units are quite common, with tens of thousands of units sold worldwide. It was also noted that GC-MS is not required. It may be needed for identification of volatiles with unknown samples, but retention time matching (to standards) with GC-FID is an option when there is some idea of the volatiles present in the sample. In response to a comment that there was no data to support a correlation between the headspace method and the volatility profile of ASTM D2369, data were presented on the percent weight loss of Texanol from a coating using the two methods. The results were shown to agree within 10%, relative. A comment that the time and temperature conditions of sampling of the headspace method do not match the conditions of ASTM D2369 was addressed. Because the static conditions lack the air flow of the dynamic conditions of D2369, it is not unexpected that the time and temperature conditions used in D2369 are different. The temperature and time conditions for the headspace measurement were selected to give the best correlation with the results of D2369. The future plans for the task group were summarized: (1) complete an assessment of the factors affecting water content effects, (2) explore an internal standard approach using the separative part of the existing method, (3) complete a new round robin by this fall, (4) cooperate with California Polytechnic professors, M. Wills and D. Jones, in their assessment of this test method, (5) re-ballot to Subcommittee 21 before the January 2006 D01 meeting.

Water Content by Calcium Hydride -- The purpose of this new task group on is to explore the potential of applying a method developed for used oil samples, as an alternative to the Karl Fischer method for determining water content in some paints and coatings. The group chair, T. Lynn, gave a short summary of the Calcium Hvdride Method, which depends on the reaction between the hydride and water to produce hydrogen gas. The amount of water can be determined from the pressure exerted by the gas. Data from preliminary experiments by four different labs using the new method on various paint samples were distributed to the attendees. The purpose of these experiments was to provide an opportunity for interested labs to become familiar with the method and to investigate the possible utility of the method. There was considerable discussion as to possible improvements in the method, including a section on interferences, the use of a cap on the syringe during weighing, and an alternative sample size/preparation for low water content samples. Based on these preliminary observations by the participants and the group, it was decided that further work on the method was merited. Dr. Lynn agreed to rewrite the method including the suggestions of the group and distribute a new draft of the method for comment.

The VOC Credit for Cure Water group exists because the water of reaction from coatings that cure by condensation mechanisms is currently treated as a VOC. A test method for measuring the cure water would allow more accurate VOC measurements when condensation reactions are involved. Such a method has been written, revised, balloted and reballoted. Results of the latest subcommittee ballot were discussed at this meeting. The method will be revised and balloted again. A round-robin needs to be carried out to provide precision data. Before D01 balloting can be done, there needs to be at least a repeatability statement in the test method. This statement could be developed from currently available within lab data.

The group on the "Practice for Determining Volatile Organic Compound Content (VOC) of Paints and Related Coatings" reviewed the results of the recent ballot, which generated no negatives and a few comments that will be incorporated where appropriate. The purpose of the revision was to add t-butyl acetate to the exempt volatile compounds used in coatings listed in the appendix. In addition, the entire Appendix 3 was rewritten in order to simplify it and to bring references up to date. The paragraph in the Scope concerning the description of exempt volatile compound has been revised.

Exploratory Analytical Research -- Chair Fujimoto described the new technique for water in paints using a Quantitative Calcium Hydride Test Kit that is now being evaluated. The calcium hydride method is a new approach to the determination of water in paints and related products, in which the hydride reacts with the water and produces hydrogen gas. The pressure of the gas in the sample tube is measured by inserting a hand held pressure meter designed to convert pressure to volume or weight percent water in the paint. Since the reaction between the calcium hydride and water is stoichiometric, a direct relationship is claimed to exist between pressure and concentration. The chairman asked if there were any suggestions for test methods that should be developed and standardized for the paint industry. He asked attendees if there was a need to develop a method to identify organic acids used to catalyze crosslinking systems, or if a method to find the cause of craters, i.e., silicone oil or incompatible contaminants was needed. No suggestions were made. Any D01 members with proposals for new or needed test methods should address these to Chairman Fujimoto.

D01.23, Physical Properties of Applied Paint Films

P. Guevin, Chair

The group on adhesion heard a report that the three adhesion standards; D 2197, "Test Method for Adhesion of Organic Coatings by Scrape Adhesion," D 3359, "Test Methods for Measuring Adhesion by Tape Test," and D 5179, "Test Method for Measuring Adhesion of Organic Coatings to Plastic Substrates by Direct Tensile Testing," are up-to-date. An email was received from Taiwan asking about companies that comply with D2197. The two companies in the United States that manufacture the apparatus conform to the apparatus specified in the standard. A company who expressed interest in a blister adhesion test contacted P. Guevin, who referred the caller to a NIST document, which discusses a shaft-loaded blister test (SLBT). F. Gelfant informed us that D01.46 had drafted a test method to measure the adhesion of organic coatings to concrete.

Dry Film Thickness -- A. Freidenfelds, Chair, led the group in discussing the negative votes from A. Beitelman and I. Sellars on the proposed "Practice for Nondestructive Measurement of Dry Film Thickness of Nonmagnetic Coatings Applied to Ferrous Metals and Nonmagnetic, Nonconductive Coatings Applied to Non-Ferrous Metals." Mr. Beitelman withdrew his negative after the group agreed on editorial changes. The negative vote from Mr. Sellars was more difficult. The group agreed that Appendix I could be improved, but Mr. Sellars written rationale did not help the group revise Appendix I to show a better balance on the use of foils vs. coated standards, which was needed to resolve the negative vote. The group voted to find the negative vote not persuasive and decided that the proposed practice should be published as is after incorporating a number of editorial changes. However, a proposed revision drafted by J. Fletcher was discussed and found to have merit. It was agreed that the task group would immediately begin to revise Appendix I as suggested by Mr. Fletcher. The group also recommended that D1400, "Test Method for Nondestructive Measurement of Dry Film Thickness of Nonconductive Coatings Applied to a Nonferrous Metal Base," be balloted for reapproval to insure its continuity. At the meeting, Mr. Freidenfelds was presented with the 2005 Task Group Chair of the Year Award for his outstanding leadership in running the task group.

P. Guevin, Chair of the Hardness, Mar and Abrasion Resistance group, reported receiving revisions of D968, "Test Methods for Abrasion Resistance of Organic Coatings by Falling Abrasive" and D4060, "Test Method for Abrasion Resistance of Organic Coatings by the Taber Abraser" from Taber Industries. They met with his approval as they bring the abrasive specifications up-to-date. After the necessary Work Item Numbers are obtained, the revised test methods will be submitted for D01.23 ballot. P. Guevin received an email request for information on the RCA Tape Abraser and any ASTM method for it. He said that F 2357, "Test Method for Determining the Abrasion Resistance of Inks and Coatings on Membrane Switches Using the Normal Tool 'RCA' Abrader," from Committee F01 on Electronics, describes the apparatus and covers its use. C. Schoff offered to review the hardness test methods such as the Sward Rocker Hardness Tester that will be up for reapproval or revision next year. He will propose revisions where necessary.

Contact Angles -- C. Schoff, Chair, reported that this meeting was scheduled in order to reactivate work on a contact angle method (or practice or guide). Contact angles are useful for characterizing surfaces for wettability, cleanliness, and other surface properties. A draft method for measuring contact angles was circulated in 1996, but never balloted. The 1996 draft was handed out along with a paint company's test method for solid surface tension based on contact angles of water and methylene iodide. It was quickly decided that the initial document should be a guide. This standard would be a guide to the contact angle instrumentation that is available, when to use it and what the results mean. The Chair will contact manufacturers and obtain information on their instruments and also invite them to attend the next meeting. The Chair also will prepare a first, rough draft of a guide for review at the January 2006 meeting.

The group on Exploratory Research heard that ASTM D6991, "Test Method for Measurement of Internal Stresses in Organic Coatings by Cantilever (Beam) Method," has been published. Dr. Y. Korobov has offered to conduct a one-day course to instruct the proper use of this test method. There was interest by one member in such a course C. Schoff said that D. Perera (CoRI, Belgium) has published similar test method technology.

D01.24, Physical Properties of Liquid Paints and Paint Materials

C. Schoff, Chair

Negatives and comments resulting from the ballot on the revision of D 5201, "Practice for Calculating Formulation Physical Constants" had already been considered and corrections/changes were presented. Some of the problems with this practice have been due to the inability of the ASTM electronic balloting system to handle complicated equations in the draft methods being shown. We hope that this difficulty has been overcome and that the practice will be able to move forward. The revised practice includes HAPs calculations as well as those for VOC, which will extend its use.

The group on Dispersion Phenomena had a brief meeting. Suggestions for new standards included a guide or practice for evaluating the degree of flocculation and some other method besides the Hegman gauge for evaluating grinds. The Efflux Cups group discussed three methods that had been balloted for reapproval: D1200 Ford Cup, D4212 Dip Cups and D5125 ISO Cups. All passed with no negatives, but each attracted several comments. Editorial changes were made based on the comments. One voter, T. Reith, pointed out that the 10-minute shaker conditioning requirement prior to measurement in D1200 was not needed by all paints and could cause foam generation and entrapment. Neither of the other two methods requires shaking. This section was not changed at this time, but all the cup methods will be revised to address this problem and to be consistent with each other.

The group on Rotational Viscometers discussed D2196, "Rheological Properties of Non-Newtonian Materials by Rotational (Brookfield Type) Viscometer," which had received a negative and several comments. The negative was withdrawn after an editorial change and several other editorial changes were made. The method will be published in August, D4287 "High Shear Viscosity Using a Cone/Plate Viscometer" had been reapproved recently, but the method will be reviewed and revised taking into account that new instruments are independent of AC frequency and can be set at 10,000 or 12,000 [s.sup.-1]. The scope and apparatus sections will specify a shear rate of 10,000 to 12,000 [s.sup.-1]. The group discussed a possible low shear cone/plate method and D. Beltran volunteered to work on it.

D01.25, Evaluation of Weathering Effects

M. Crewdson, Chair

Visual Evaluations -- The group heard that the re-approvals that were discussed at the last meeting have not yet been done. The four standards that were discussed at the last meeting were D 660. "Evaluating Degree of Checking of Exterior Paints," D 661, "Evaluating Degree of Cracking of Exterior Paints," D 662, "Evaluating Degree of Erosion of Exterior Paints," and D 772, "Evaluating Degree of Flaking (Scaling) of Exterior Paints," will be sent immediately for D01 ballot for re-approval.

M. Crewdson presented the latest draft of Work Item WK4018 "Reporting of Weathering Results and Coatings Defects" for review. Several changes are being suggested, and were discussed during the meeting: (1) Changed title by adding "and Coatings Defects," (2) added new section to draw attention to the fact that this is only meant as a template, added instrumental methods, (3) added a new section explaining the use of the template report form, (4) changed the term "trace" to a rating of 8 (previously 9) to comply with D01 Handbook, (5) changed the Figure showing the Report Form to an example instead of showing a blank form and (6) removed any reference to this being a revision of D1150. The revised document will be sent for subcommittee ballot.

Scanning Techniques -- Chair S. L. Chong gave a presentation to the subcommittee on the revision of D 7087 "Standard Method for an Imaging Technique to Measure Rust Creepage at Scribe on Coated Test Panels Subjected to Corrosive Environment." The method was approved by the D01 in March 2005 and was published in April 2005. To improve the Precision section, a second inter-laboratory round robin test was conducted at the PACE 2005 Conference in which many State DOT engineers attended. Six operators from different laboratories participated in the test; each operator traced the rust creepage area around the scribe line in duplicate on each of three weathered test panels. The repeatability at the 95% confidence level was found to be 12.3%, 8.3%, and 4.9% for measuring rust creepage of 2.2 mm, 3.4 mm, and 8.8 mm, respectively. The reproducibility at the 95% confidence level was found to be 22.9%, 29.3%, and 6.3% for measuring rust creepage of 2.2 mm, 3.4 mm, and 8.8 mm, respectively. These data replaced the previous precision data and the revised precision section was balloted by D01. There were no negatives, and the subcommittee agreed to have this updated document printed as it is. A report on the calculation of the repeatability and reproducibility will be prepared later and then will be reviewed by the subcommittee before its submission to ASTM as a research report. A footnote or a note will be then added to the Precision Section to quote this report. One more round robin test will be conducted after the method procedure is written in more detail; a lower variability is expected.

D01.26, Optical Properties

N. Barnes, Chair

The proposed Guide Protocol for how a supplier and customer set a color specification for a material had been submitted for subcommittee ballot. Comments from the ballot were addressed and E. Carter is to update the guide and submit it for main committee ballot. Comments from the recent ballot on D2805 "Hiding Power of Paints by Reflectometry" were discussed. The main point was the similarity between charts supplied by The Leneta Company and BYK-Gardner. It was agreed the sole supplier statement must be removed, but that a statement should be added in the precision and bias sections, to indicate that these values are based solely on the charts supplied by The Leneta Company. A discussion of distinctness of image concluded that there is no demand for a DOI method based on the BYK-Gardner Wavescan. The subcommittee has been approached to provide a method for hiding power of paint over fluorescent primers. Work on this standard will progress after ASTM E12 specifies the UV light source requirements. Separation of dispersion aspects of tint strength methods from the tint strength measurement itself will be discussed at the January 2006 meeting.

D01.28, Biodeterioration

K. Roberts, Chair

The group on the New Environmental Chamber Method reviewed the latest draft of the test method titled "Resistance to Mold Growth on Interior Coated Building Products in an Environmental Chamber." The discussions focused on clarifying the wording to convey the intent of the group. Major discussion points included the humidity control in the chamber, untreated controls to check the ability of the chamber to promote fungal growth and "conditioning" of samples prior to testing. The group working on the revision of D3274 "Evaluation of Fungal Disfigurement of Paint Films" rated paint films provided by M. Crewdson. He asked the attendees to use the proposed grading scale to rate each specimen for the degree of disfiguration by fungal growth. The results will be tabulated to determine if this new grading scale is more reproducible from user to user.

DIVISION 30 PAINT MATERIALS

D01.31 on Pigments

J. Peake, Chair

The group on Titanium Dioxide discussed D3926, "Standard Test Methods for Percent Solids in Titanium Dioxide Slurries," which had been revised by R. Morrison to address negative votes and placed on a recent D01 ballot. The ballot item received no negatives and two comments. The group decided that both of the requested changes could be made editorially. J. Peake will ask R. Morrison if he will make those changes and send the method for publication.

The Pigment Specifications group faces a large number of standards that require action, many of which will go to D01 ballot after editorial changes, but D261, Standard Specification for Iron Blue Pigment and D262, Standard Specification for Ultramarine Blue Pigment remain stalled due to lack of reviewers. If no one steps forward to look at them, they will be balloted for withdrawal.

At the conclusion of the meeting, there was discussion of how to get more members of D01.31 to participate and attend meetings. One suggestion was to list the activities and what participation will be needed at an upcoming meeting and publish that in Standards to encourage attendance. Publishing agendas on the D01 web site might also help.

D01.34, Naval Stores

J. Russell, Chair

The group on Determination of Neutral Content heard J. Russell's report that the aim of the work continues to be the development of a more rapid method for the measurement of the neutral content of tall oil fractions without the use of diethyl ether. The basis of the method is the use of solid phase extraction columns to separate the neutrals from the acid components of the tall oil fractions. At the January meeting it was decided to concentrate future work on tall oil fractions, such as tall oil fatty acids, rosin, and distilled tall oil. The results reported at the current meeting were inconsistent with the most encouraging results being obtained with tall oil fatty acids using hexane as a solvent. It was agreed that there appeared to be no single solvent that would be suitable for fatty acids, rosin, and DTO and that each material would require a different solvent.

Consequently it was agreed to concentrate the immediate future effort on tall oil fatty acids. New samples will be distributed. All participants will run the DuBose method at least five times using hexane as the solvent and report their results at a telephone conference call, tentatively scheduled for sometime in October.

J. Russell reported to the group on Color of Rosin and its Derivatives on the status of the project to have the FDA and the Food Chemical Codex (FCC) change the wording of their regulations covering rosin to reflect that industry now uses Gardner colors and not the USRG scale. It was decided to amend the specifications of the rosin derivatives listed in the Food Chemical Codex prior to approaching the FDA. Consequently the color specification in the FCC descriptions of four rosin esters has been submitted to the Technical Committee of the FCC for comment. No comments had yet been received from the FCC. In the course of this work it was realized that ASTM D509, "Test Methods for Grading Rosin," also needed updating as it did not include the use of the Gardner color scale. D509 has since been modified and balloted. No negatives were received and the method will become a 2005 standard method. D509 still does not include a procedure for sample preparation when using the Gardner scale. It was agreed that J. Russell would prepare a draft of such a section for discussion and review at the January 2006 meeting and it would be balloted shortly thereafter. J. Russell also suggested that the change to the Gardner scale should be even broader than updating the FDA regulations and the Gardner scale should become the global standard. He suggested that a global round robin be held to demonstrate the improved precision of the Gardner scale method. The subcommittee supported this suggestion and it will be discussed further at the subcommittee meeting in January.

D 01.35, Solvents, Plasticizers & Chemical Intermediates

R.G. Montemayor, Chair

A number of overdue standards under the responsibility of this subcommittee have been revised to include reference to ASTM E 29, "Standard Practice for Using Significant Digits in Determining Conformance to Specifications," as well as to provide information that ASTM D 5386 "Standard Test Method for Color of Liquids by Tristimulus Colorimetry" should be used for color. Problems associated with insufficient attendance at the subcommittee meetings continue, and efforts to maintain the various standards under the jurisdiction of the subcommittee are being impacted negatively.

The group on Hydrocarbon Solvents and Ketones revised and balloted the following standards: D 740 "Standard Specification for Methyl Ethyl Ketone," D 1153 "Standard Specification for Methyl Isobutyl Ketone," and D 3734 "Standard Specification for High Flash Aromatic Naphthas." An inquiry was received from the U.S. Army regarding VOC determination for solvents. Subcommittee D01.21 will be consulted for information.

The Reactive Monomers group revised and balloted the following methods and specifications: D 2192 "Purity of Aldehydes and Ketones." D 3362 "Methanol Content of Formaldehyde," D 3541 "Specification for 2-Ethyl Hexyl Acrylate," D 3845 "Specification for Glacial Methacrylic Acid," and D 4415 "Determination of Dimer in Acrylic Acid." D 1078 "Boiling Range of Volatile Organic Solvents" was also balloted to remove reference to the word "asbestos" in the body of the standard.

The Chemical Intermediates group revised and balloted the following standards and specifications: D 304, "Specification for n-Butyl Alcohol," D 331 "Specification for 2-Ethoxyethanol," D 770 "Specification for Isopropyl Alcohol," D 1007 "Specification for Sec. Butyl Alcohol," D 1258 "STM for High-Gravity Glycerin," D 1612 "STM for Acetone in Methanol," D 1719 "Specification for Isobutyl Alcohol," D 2195 "STM for Pentaerythritol," D 2694 "Specification for Diethylene Glycol," D 3622 "Specification for 1-Propyl Alcohol," D 3546 "STM for Formic Acid in Glacial Acetic Acid," and D 5164 "Specification for Proypylene Glycol and Dipropylene Glycol."

The group on Plasticizers and Esther Solvents balloted the following standards concurrently at the D01.35 and D01 level: withdrawal with no replacement of D 1399, "Unsaponifiables in TCP"--no current users; revision to D 4614, "Specification for Ethyl Acetate"; withdrawal with no replacement of D 363, "Specification--Tricresyl Phosphate"; revision to D 1209, "Color of Clear Liquids (Platinum Cobalt Scale"; revision to D 608 "Specification--Dibutyl Phthalate"; withdrawal of D 1468, "Volatile Matter in TCP"; and revision to D 1617, "Ester Value of Solvents." D 363, D 1399, and D 1468 have been withdrawn successfully with no replacement (TCP--tricresyl phosphate--is no longer used).

D01.37, Ink Vehicles

D. Weisel, Chair

The New Membership group met to discuss ways to attract new members. Consolidation and tightened budgets continue to shadow industry. Chair R. Incontro will contact individuals and companies for new members and report back. D. Weisel asked attendees if a combined D01.56 (Printing Inks) and D01.37 would be more effective. He will speak to P. Ford to discuss a possible combination of the two subcommittees.

Resin Solutions -- The group discussed D5958, "Practice for Preparation of Oil-Based Ink Resin Solutions," which has been changed editorially, but which will not include the Thermotronic II, automated varnish cooker. A new practice (WK 1858) is being written to include this device along with key areas of D5958. Chair J. Head will check on the correct wording for a sole source of supply. One section details the temperature profiles for alkaline refined linseed oil and C12 to C16 hydrocarbon petroleum

distillates.

The Resin/Solvent Compatibility group discussed D6038, "Determining the Compatibility of Resin/Solvent Mixtures by Precipitation Temperature," which had been balloted for reapproval. The single negative was deemed to be editorial in nature and that and other editorial changes will be made before the method is published. The group on Rheology of Ink Vehicles discussed WK8333, "Measurement of Viscoelastic Properties of Paste Inks Using an Oscillatory Rheometer." The research report will include the instruments and geometry used in the round robin. The data show that the precision is well within benchmark limits. The method will be submitted for ballot.

R. Czarnecki, Chair of the group on Thermal Stability of Energy Curable Vehicles, led a discussion of a proposed thermal stability method that will have applicability both for energy curable vehicles and energy curable printing inks and coatings. The Chair will apply for a work number and prepare a draft standard. Involvement by resin and ink manufacturers will be sought.

D01.38, Hydrocarbon Resins

J. Bryson, Chair

J. Bryson noted that a revised version of D6493, "Softening Point of Hydrocarbon Resins by Automated Ring and Ball Apparatus" had passed D01 balloting, and will be published in 2005. The group on Instrumental Color Deterrmination heard that N. Barnes is writing a draft method for 0-0.9 Gardner color. It might not be necessary to use distilled water to set zero absorbance. Fresh, spectograde, deionized water should be adequate. For use with resin solutions, it would be convenient to use an organic liquid for zeroing the instrument; spectrograde cyclohexane is relatively inexpensive. One advantage of a low-range Gardner-color scale is that producers and users will not have to change color scales below Gardner 1. New instrumental methods being revised include glass transition by differential scanning calorimetry, molecular weight by gel permeation/size exclusion chromatography and determination of volatiles by thermogravimetric analysis.

DIVISION 40 PAINT PRODUCTS APPLIED ON SITE

D01.42, Architectural Finishes

N. Rogers, Chair

The group on Water Repellency of Wood discussed WK 4926, the revision of D4446, "Standard Test Method for Anti-Swelling Effectiveness of Water-Repellent Formulations and Differential Swelling of Untreated Wood When Exposed to Liquid Water Environments." D4446 requires the use of 10-inch wood wafers that are becoming more and more difficult to obtain. The revision will incorporate use of 5-inch wafers to conform to the proposal of the American Waterproofing Association. The Chair, T. Tuznik, reported that five ponderosa pine parent boards (10-inch wafers) have been qualified. Two solvent and two water based water repellent formulations need to be identified for use in the round robin. Five ponderosa pine parent boards (5-inch wafers) need to be qualified for use in the round robin.

Acting Chair, T. Sliva, reported to the group on Wet-Edge Times of Latex Paints that, upon review of the task group history, it was discovered that a practice had been balloted by the subcommittee in 2002. The practice had received negatives, but due to the resignation of the task group chair, those negatives had not been addressed. C. Hawkins volunteered to chair the group and will circulate the information on the negatives to the members.

D. Mall, Chair of the group on Low Temperature Application of Latex Paints presented a draft of the proposed "Standard Practice for Low Temperature Film Formation of Latex Paints." The group reviewed the draft and suggested changes. A new draft will be sent to all group members. He also presented a draft of "Standard Practice for Touch Up" to the group on Low Temperature Film Formation.

The "Standard Practice to Evaluate Leaching of Water Soluble Materials from Latex Paint Films" passed D01 ballot. Editorial comments from subcommittee and D01 ballots were reviewed, accepted and will be incorporated, after which the new standard will be published. The group on Testing Exterior Deck Coatings received copies of ASTM D6763 "Standard Guide for Testing Exterior Wood Stains" with recommended additions and deletions towards turning it into a deck coatings document. The group offered additional revisions to the guide so that it would be better suited to the category of deck coatings. A draft of the guide incorporating all these recommendations will be distributed to group members for their approval and then will go to subcommittee ballot.

D01.44, Traffic Coatings

P. R. Guevin, Chair

The Thermoplastics group heard that J. Britt's revision of D 4960, "Test Method for Evaluation of Color for Thermoplastic Traffic Marking Materials," had resulted in three distinct parts from which he drafted two new standards: a Practice for Sampling Thermoplastic Materials and a Practice for Preparing Samples. They will be submitted for D01.44 ballot.

Traffic Marking Materials -- P. Guevin reported to the group on his efforts to revise D 913, "Test Method to Evaluate Degree of Resistance to Wear of Traffic Paint." S. Chong of the Federal Highway Administration (FHWA) suggested he contact M. Griffith (FHWA) who should provide some guidance on ways to digitize wear patterns and make the test method less subjective. P. Guevin reported on his attempt to revise D 969, "Test Method for Laboratory Determination of Degree of Bleeding of Traffic Paint," and remove reference to asbestos felt. He called M. Noone, Chair of D08.02 on Prepared Roofing, Shingles and Siding Materials, regarding a reference to their D 4869, "Specification for Asphalt-Saturated Organic Felt Underlayment Used in Steep Slope Roofing." D 146, "Test Methods for Sampling and Testing Bitumen-Saturated Felts and Woven Fabrics for Roofing and Waterproofing," was suggested as a specification for coal-tar saturated felt. S. Chong suggested contacting E. Bastian (FHWA) who should provide some guidance on this substrate.

The Night Visibility group heard reports from P. Guevin on D 1155, "Test Method for Roundness of Glass Spheres," and D 1214, "Test Method for Sieve Analysis of Glass Spheres," both of which had been balloted in error. When these two items received negative votes, they were withdrawn from ballot. P. Guevin received "internal" round-robin data on these test methods from Potters Industries. He will determine if they can be analyzed by ASTM as part of the new Interlaboratory Studies (ILS) program. The National Cooperative Highway Research Program contacted several D01.44 members regarding a research proposal to evaluate single particle optical sizing instruments as viable instruments to replace the roundometer specified in Test Method D 1155 and the standard sieves specified in Test Method D 1214. D01.44 will follow their progress.

D01.45, Marine Coatings

E. Haslbeck, Chair

Copper Release Rate (D6442) -- During a recent ballot of D6442, "Determination of Copper Release Rate from Antifouling Coating Systems in Artificial Seawater," no negative votes were received, but several editorial changes were suggested. A final document is ready for publication. We also discussed the proposed "research reports" that document laboratories' Limit of Quantitation (LOQ) data. These reports outline the data set where LOQ measurements were made in accordance with the protocol agreed upon during the last meeting. These are being added to D6442. Guidance has been provided by ASTM with regard to referencing ISO documents/methods within ASTM methods. The subcommittee will wait until ISO documents are revised and fully harmonized with D6442 before adding (editorially) the reference to the ISO 15181-1 and 15181-2.

The group on Measuring Release Rates of Organic Biocide from Antifouling Coatings reviewed the latest version of the method (Z9489Z) and discussed Limit of Quantitation (LOQ) calculations. Arch's LOQ calculations were based on the biocide in seawater and not the biocide in distilled water (that is, in accordance with Annex 2). (Confirming this stems from January 2005 discussion of LOQ--calculating LOQ of instrument vs. LOQ of method.) Each company developed their own practical limits values. The group thought that five calibration standards from the LOQ through 200 might be more appropriate than what is currently in the method. The committee recommends to all biocide manufacturers that they write a research report that documents their LOQ data generation (in accordance with new Annex 2). Remaining open items from the January 2005 meeting: (a) revision of release rate range over which this method is valid for CDMTD; (b) precision and bias statement; and (c) addition of a bias statement that essentially states: "bias cannot be calculated because there is no 'true value' for the coatings we are testing with this method."

The Field Testing/Rating Coating Performance group discussed D4939, "Testing Panels Under Dynamic Conditions," which must be re-balloted prior to the next ASTM meeting or it will be dropped. Questions were raised regarding the formula for calculating shear. Table 2 in the current version is referred to but is missing. D3623, "Testing Panels in Shallow Submergence" received negatives on a recent ballot and will be revised and reballoted.

The group on SO TC35/SC9/WG27--D01.45 Interactions outlined recent actions of ISO TC35/SC9/WG27 regarding plans for organic biocide methods. ISO 15181-1 and 15181-2 will likely go to ballot in early fall 2005 (final harmonization will be done following this meeting) and changes placed on the six-month ballot. There will not be another ISO meeting prior to this ballot. A round robin is not mandatory for ISO, but is for ASTM and one is anticipated for the organic biocide method. Therefore, ISO suggests that, if designed carefully, by conducting all round robins concurrently, participants could minimize expense and duplication of effort. A suggestion was made to conduct a round robin on analytical standards only, and not on coatings. A new biocide, Econea - (2-(-p-chlorophenyl)-3-cyano-4-bromo-5-trifluoromethyl pyrrole)), is being registered for use in Europe and in the U.S. The company (Janssen) has asked ISO to develop the release rate method. An initial draft is expected in 6-12 months. Regarding the calculation method, it was emphasized that until paint manufacturers could validate that only 70% of the biocide was leached from the coating in practice, the regulatory authorities would continue to use a 100% release default.

The next D01 meeting is January 22-25, 2006 in Fort Lauderdale, FL. This overlaps with the MEETS (Marine Environmental Engineering Technical Symposium) meeting scheduled for January 23-24, 2006 in Arlington, VA. We normally have our meeting on Monday (January 23rd in 2006), but Liz Haslbeck is scheduled to give a talk at MEETS, and does not yet know the day of the talk. Therefore, it is possible that our meeting day will be changed to Tuesday or Wednesday. It is also possible that the meeting could be moved to Washington, DC (or surrounding area). Announcements will be made as dates are confirmed. G. Swain indicated he would delay publication of a "dynamic immersion test method" until a more robust version of the test apparatus is built and tested. L. Haslbeck re-confirmed interest of the Naval Sea Systems Command (NAVSEA) Code 05M1 (M. Ingle, D. Thomas, and A. Kaznoff) in an in-situ biocide release rate method development/publication. No current plans/funded efforts are underway. NAVSEA favors the Harbor Exposed Panel Method. Follow-up discussions are planned. Liz also made members aware of a release rate paper to be published in the August edition of the Journal of Protective Coatings and Linings.

D01.46, Industrial Protective Coatings

L. Smith, Chair

D. Weldon, Chair, reported to the Surface Preparation group that D6386, "Preparation of Zinc Hot-Dipped Galvanized Coated Iron and Steel Product and Hardware Surfaces for Painting," has been re-approved. H. Roper then gave a presentation on a paper published in the June 2005 issue of Journal of Protective Coatings & Linings (IPLC) that he co-authored with R. Weaver and J. Brandon, where they studied the effect of peak count on coating performance. Six different coatings were applied to steel panels of varying peak count and exposed in the laboratory using such tests as salt fog (B117) and cyclical corrosion/UV exposure (D5894). He reported better adhesion and less undercutting at the scribe with higher peak counts at longer exposure times. R. Stachnik showed the group the prototype of an instrument he developed for determining peak count from replica tape. The devise uses an optical method, and is suitable for field use. He stated that pre-production models will be made available to researchers.

The group then discussed the negative votes on the subcommittee ballot for WK7945, "Measurement of Surface Roughness of Abrasive Blast Cleaned Metal Surfaces Using a Portable Stylus Instrument." It appeared that the wrong version of the document had been balloted. Once the correct definitions were inserted, these negatives were withdrawn. Other items discussed included replacing the drawings in the Appendix with those in the JPCL article, and obtaining a copy of a typical report for the next ballot. A Precision and Bias Statement is needed, and a discussion was held as to whether it should be for the instrument or the blasted surface. It was decided to do both. Mr. Stachnik will generate these statements based on data supplied by Roper. An official round robin will be performed once the document has been accepted. The document will be revised and sent to D01 ballot.

Revisions to D4417, "Measurement of Surface Profile of Blast Cleaned Steel," were discussed. R. Stachnik stated that the Method C (Replica Tape) needs to be updated, including adding a description of the gauge and the burnishing tool, changing the reference method to a digital stylus recorder rather than an optical microscope, and changing incorrect descriptions of the replica tape range. L. Smith stated that more guidance is needed on the Method C rubbing method, as he has seen different motions used which gave different results in one case. R. Stachnik proposed running another round robin test as the Precision and Bias statements for Coarse and X-Coarse grades were obtained from data that included some anchor profiles outside the range of each grade of tape. L. Smith pointed out that the last round robin for the "Paint" Grade tape was performed with the test area marked off while the previous round robin for the Coarse and X-Coarse tape did not. This makes the "Paint" grade tape look better as the testing did not include any variations due to the blasting. It was suggested that the new round robin with all three grades of tape be performed both on a marked location and at a location on the plate selected by the operator so that the precision and bias of both the tape and the method can be determined. The group supported performing another round robin for Method C. R. Stachnik volunteered to lay out the round robin test for discussion at the next meeting and to start making changes to the Standard.

The Repainting group heard a report from D. Allerton, Chair, that D5402, "Practice for Assessing the Solvent Resistance of Organic Coatings Using Solvent Rubs," had passed subcommittee ballot. D. Weldon questioned the need for high-purity methyl ethyl ketone (MEK) as most people use whatever commercial grade they have available. The group agreed, so the wording will be changed. He also questioned the requirement for using a balance to gauge the pressure exerted during the rub, as running the test on a balance may damage it. The group decided that the need to quantify the pressure is important for consistent results. The intent is not to run the test while the panel is on a balance pan but to periodically check how much pressure the evaluator is using. Therefore Weldon's concern is unfounded. The document will be sent to D01 ballot.

P. Guevin gave a short presentation on D5859, "Test Method for Determining the Traction of Footwear on Painted Surfaces Using the Variable Incidence Tester." The committee responsible for this document does not have the expertise for developing a standard to prepare the test panels used in the test. The task group decided that such a document would be easy to develop as D7055, "Practice for Preparation (by Abrasive Blasting) of Hot Rolled Carbon Steel Panels for Testing of Coatings," can be referenced for the surface preparation portion. D. Weldon and W. Corbett will develop this Practice.

F. Gelfant opened the meeting of the Adhesion group by distributing the results of pull-off strength tests performed in his laboratory where five replicate pulls were performed using five instruments on several different coating types and different dolly sizes. These data will be used to develop the initial precision and bias statement prior to performing a round robin test. He then went on to discuss the comments received on WK7924, "Test Method for Pull-Off Strength of Coatings on Concrete Using Portable Adhesion Testers." Two subcommittee members provided comments. WK7924 was sent to members of Committees C03 and D33, who provided eight other comments. D. Beamish suggested changing the failure time from 10 to 30 seconds to 5 to 30 seconds due to the low pull-off strengths sometimes encountered with concrete. He also suggested making the one-year calibration frequency a recommendation and not a requirement. Both of these suggestions were adopted. W. Corbett suggested clarifying the fact that scoring be performed before attaching the round loading fixtures. There was considerable discussion as to whether the procedure should require or indicate a preference for a given or minimum dolly size (such as two inches in diameter). The task group was unaware of any test data that showed one dolly size being better than another. It was decided not to recommend a preferred dolly size. Identifying the dolly size is one of the items in the reporting requirements.

G. Hall was also concerned that the use of a penetrating primer may not give true adhesion values if this method was used. It was decided that any discussion on penetrating primers was beyond the scope of this document. M. Sprinkel suggested that the tensile strength of concrete be identified at 7 to 7.5% of the compressive strength rather than the 8 to 12% currently used in the document. The value used in the document comes from reputable sources, so it was decided not to make the change. M. Sprinkel also recommended coring 1/4-inch into the concrete rather than just breaking through the coating. The depth of coring has been the topic of deliberations and review of test data by the task group. It had previously been decided that deeper scoring was more appropriate for G1583, "Test Method for Tensile Strength of Concrete Surfaces and the Bond Strength or Tensile Strength of Concrete Repair and Overlay Materials by Direct Tension (Pull-Off Method)," as it facilitates substrate failure, whereas WK7924 is concerned with pull-off strength of coatings on concrete.

Y. Ohama recommended a different method for classifying failure modes. The recommendations were reviewed and found to be quite complex compared to the current method, and of unnecessary precision. T. Stanley submitted suggestions for a Precision and Bias statement, while M. Diaz and A. Beggs submitted numerous editorial comments. The document will be submitted to D01 ballot after all the changes are made.

L. Smith, Chair, led a brief discussion on the round robin test planned for D4541, "Test Method for Pull-Off Strength of Coatings Using Portable Adhesion Testers." It was decided to hold the round robin at the SSPC annual meeting in Tampa, FL in February 2006. SSPC has graciously donated a room for two days so that dollies can be glued and cured, and pulls performed. L. Smith will coordinate with D. Beamish on organizing the panel suppliers, notifying the equipment suppliers, and developing the instructions/data forms. ASTM headquarters will be contacted for assistance.

Inspection -- L. Smith, Chair, informed the group that D3276, Guide for Painting Inspectors (Metal Substrates), passed subcommittee ballot. W. Corbett commented that SSPC-SP14/NACE 8 and SSPC-SP15 needed to be added to the References section and body of the document. L. Smith presented suggested wording which was modified and accepted. The document will go to D01 ballot.

The group on the Testing Guide discussed D6577, "Guide for Testing Industrial Protective Coatings," which had received negative votes from M. Crewdson and N. Searle. Both of these negatives concerned references to standards for accelerated weathering by carbon arc, xenon arc, and fluorescent UV lamps that have been withdrawn. They were found to be persuasive. N. Searle also presented information on carbon arc and xenon arc equipment and/or exposure. This information was incorporated into the document. D6577 will be sent to joint D01/D01.46 ballot. G. Gardner reminded the group about an earlier suggestion that ASTM should publish a book containing the Guide and its referenced documents. G. Gardner and L. Smith will pursue this endeavor.

Graffiti Resistance -- D. Allerton, Chair, presented a brief discussion on changes needed to this document. Currently it takes 60 panels to test four marking materials and five cleaning agents in triplicate. This number can be drastically reduced by allowing multiple tests on one panel, i.e., using one cleaning agent per panel by applying the four marking materials to one panel. It was also recommended to remove the washability tester option, as the sponge gets saturated with the marking material. The need for quantitative measurements of color and gloss was questioned, as visible differences are the common evaluation criteria when graffiti removal is performed in the field. D. Allerton also suggested eliminating recleanability as it requires a lot of work for very little benefit, and changing the rating scale to include degree of coating failure. Other suggestions by task group members included reevaluating the list of marking materials to focus on those commonly used by graffiti artists, and adding xylene or mineral spirits to the list of cleaning agents. R. Eritano stated that professional cleaning firms use proprietary blends of solvents, so provisions should be included for allowing those to be tested. D. Allerton will make changes to the document for discussion at the next meeting.

Salt -- W. Corbett, Chair, informed the task group that SSPC had recently published a Guide on methods for retrieval and analysis of soluble salts from steel substrates. M. Damiano had previously voted negatively on WK3049, "Practice for Assessing the Concentration of Soluble Chlorides on Metal Substrates," as it infringed on SSPC's document. A discussion on the relationship between D01.46 and SSPC ensued. Those present who have been members of both organizations pointed out that 20 years ago the areas of responsibility were better defined. ASTM D01.46 was responsible for test methods while SSPC concentrated on the interpretation of the test results. Thus, D01.46 would be responsible for measuring salt concentrations, while SSPC would focus on recommendations for acceptable salt levels for various coating types or exposure environments. It was also pointed out that ASTM has the requirement to develop precision and bias statements for test methods which would be a benefit to users. Mr. Damiano agreed to work with D01.46 on this and future endeavors.

Meeting of the Subcommittee, Industrial Protective Coatings -- Two new proposed standards were discussed. A method to replicate and measure concrete surface roughness prior to painting was tabled until the January 2006 meeting. The other method was a standard procedure for determining the presence of oil in recyclable abrasives. The group found this to be of interest and will start work on developing the document. ASTM has made a commitment to assist committees in preparing research reports, including in performing the round robin tests. L. Smith will contact ASTM staff about assistance for the D4541 round robin. He also reported receiving a request for two reviewers, each, for two chapters of the latest revision of the Paint Manual. I. Cheng volunteered to review the chapter by D. Weldon on Testing of Industrial Maintenance Coatings. A. Beitelman and L. Smith volunteered to review the chapter on Prevention of Metal Corrosion with Protective Overlays by K. Tator and C. O'Malley.

D01.47, Masonry Treatments

T. Sliva, Acting Chair

The group on Water Vapor Transmission of Treated Substrates discussed the need to start a round robin for precision data for ASTM D 6490, "Standard Test Method for Moisture Vapor Transmission of Non Film Forming Treatments Lised on Cementitious Panels." F. Gale, Chair, led the group on Alkali Resistance of Masonry Treatments in a discussion of work on the development of a proposed standard practice for determining alkaline resistance on concrete and masonry. She will prepare a draft of the standard and have it ready for review by the January meeting.

The Anti-Graffiti Coatings group discussed the proposed "Standard Practice to Determine the Effectiveness of Anti-Graffiti Coatings for Use on Concrete, Masonry and Natural Stone Surfaces by Pressure Washing" that had passed a subcommittee ballot. The new revision was reviewed by the task group. The method will be submitted for D01 ballot before the January meeting. The group on Effectiveness of Field Applied Water Repellent Treatments Using a RILEM Tube, discussed the proposed standard, which had been distributed to members of D01.47 for review prior to the meeting. The comments received were reviewed and additional comments from attendees will be included in the next revision.

D01.52, Factory Coated Wood Products

M. Foster, Chair

This subcommittee, like a number of others, is suffering from lack of support. The attendees began by reviewing work items for weathering test methods, including D 5722, "Accelerated Outdoor Weathering of Factory Embossed Hardboard...." D 5235, "Microscopical Measurement of Dry Film Thickness of Coatings on Wood Products," needs a precision and bias statement. A round robin had been carried out, but variation was considerable and was worse on retesting six months later. A new round robin will involve six laboratories. D 358, "Specification for Wood to be Used as Panels in Weathering Tests of Coatings" has been reassigned to another subcommittee.

D01.53, Coil Coated Metal

C. Gosselin, Chair

In the Pretreatment of Substrates group meeting, C. I ligginbotham asked if methods are in place for all the non-chrome pretreatments. Attendees from pretreatment companies reported that the chrome-free alternatives are based on zirconium, vanadium, or molybdenum chemistries and the suppliers of these pretreatments have analytical methods. Should they be ASTM methods? J. Pierce and J. Favilla volunteered to head a group to decide what should be done. There was discussion about the precision of the existing methods. J. Peake will look at information from past meetings and report at the next meeting.

Accelerated Weathering -- Twelve years ago a weathering study was begun to attempt to correlate accelerated weathering results of coil-coated panels to real-time weathering in south Florida. The outdoor exposure is now completed. The study consisted of 23 sets of samples of varying topcoat chemistry, pigmentation, and color. Each set was exposed in South Florida in addition to various accelerated exposure methods. Panels were monitored over time for washed and unwashed DG and DE, and chalking. D. Cocuzzi had arranged the exposed panels in the meeting room for observation. He also presented the Florida weathering data and demonstrated the ranking method (Spearman rank correlation) of looking for correlation with the Florida data at several time points. He asked the attendees for other ideas of properties to measure. Plenty of unexposed panels are available. Perhaps there is a different way to describe color change (DL or Dc)? Other suggestions included measuring film thickness or molecular weight changes in the topcoat. Attendees wandered about the room inspecting the panels and discussing the analysis. Proposals included: (1) exclude the mildewed panels from the analysis, (2) separate the analysis into dark colors and light colors, (3) carry out separate analyses for each coating chemistry to see which accelerated method most closely matches outdoor exposure for each type, (4) look at the accelerated methods vs. the lower-year exposures in Florida, (5) look for correlation between accelerated methods, (6) look for complementary methods used for automotive coatings that may be useful for this analysis, (7) compare initial film thickness to exposed film thickness, and (8) make the data available for individuals to analyze as they wish.

The Dry Film Thickness group heard from C. Gosselin. He stated that the status of the dry film thickness method, D 5796, "Standard Test Method for Measurement of Dry Film Thickness of Thin Film Coil-coated Systems by Destructive Means using a Boring Device," is that we are working on the precision and bias statements and are preparing for another round robin study. D. Cocuzzi, C. Gosselin, and J. Henderson will present the plan at the next D01.53 meeting.

The Solvent Rub Tester group discussed the new solvent rub method using a mechanical rub tester. (Z9405Z, "Test Method for Determining the Relative Resistance of a Coated Surface to Solvents using a Mechanical Rubbing Machine.") The method was revised and that revision (WK848) will be on the next subcommittee ballot.

D. Cocuzzi is reviewing D 3794, "Standard Guide for Testing Coil Coatings," which is up for its five-year review. He will add references to the relevant solar reflectance and emittance methods. He asked if D 3794 should include any steel or aluminum methods. C. Gosselin will give D. Cocuzzi a list of candidate methods and he will review and make suggestions at the next D01.53 meeting.

The subcommittee has been discussing creating a wet stack method. C. Higginbotham asked what the objective of the method should be: an accelerated method or an actual exposure method. C. Higginbotham will draft a method to standardize actual exposure. Perhaps later we will pursue an accelerated method. C. Higginbotham initiated a discussion of the t-bend test method: D 4145, "Standard Test Method for Coating Flexibility of Prepainted Sheet." He has noticed different results depending on how the bend is flattened (roll-bend vs. v-bend). Should ASTM provide guidance? B. Rieder volunteered to revise the method, adding reference to the equipment to make the bend.

D01.55, Factory Applied Coatings on Preformed Products

R. Polovich, Chair

The June 2005 meeting was lightly attended. Several methods went out for ballot, most with editorial upgrades. D0333 "Standard Guide for Clear and Pigmented Lacquers," D5201 "Standard Practice for Calculating Formulation Physical Constants of Paints and Coatings," and D2805 "Standard Test Method for Hiding Power of Paints by Reflectometry," will be sent out for re-balloting to approve several critical changes. A new practice WK5391 "Standard Practice on Environmental Technology Verification (ETV) of Liquid Coating" has been approved for balloting. This practice provides a format for third party verification of a liquid coating for entry into the market place.

D01.56, Printing Inks

P. Ford, Chair

D01.56 continues to look for more participation from printers. There is also an interest in adding membership in the area of energy curable inks and raw materials. The subcommittee voted unanimously to recommend E. Kobylarz for an appreciation award for the work he has done on several very difficult task groups.

R. Incontro, Chair, reported to the Fineness of Grind group that the last two ballots were being withdrawn. He will prepare a new ballot item that will include all manual and automatic drawdown procedures on the grind gauge. This will include a new precision statement along with an explanation of why there is no pooled reproducibility data. P. Ford reported that J. Fetsko is re-writing the tinting strength procedure to include the use of the Flacktek/Hauschild Speed Mixer for the preparation of bleaches. P. Ford, Chair, reported to the Ink Emulsification group that there had been no success in determining appropriate and achievable standard settings for the Lithotronic computer controlled emulsification tester. It was felt that this test required leadership from the instrument manufacturer to progress. B. Cook will be contacted to see if he would assume this role.

The Ink Mileage group heard D. Ness, Chair, report that method for "Ink Mileage of News Ink on Newsprint" had passed D01 ballot. It passed with a definition for mileage in terms of g/[m.sup.2]. A comment was received that a better definition would be in terms of [m.sup.2]/g. Duane will talk to ASTM about making a comment in the procedure to this effect. The group on Degree of Radiation Curing was told that E. Kobylarz has written a clarification to insure that the procedure was not incorrectly applied to comparisons between energy curable inks of different chemistries. A revised method will be resubmitted for D01.56/D01 ballots. A research report will also be finalized.

The group on VOC of Energy Curable Ink heard from the new Chair. G. Pace, that he will evaluate D5403, "Standard Test Method for Volatile Content of Radiation Curable Materials." It is believed that this test method works well for materials designed for thick film application and curing but may be inappropriate for thin film inks. He will evaluate the thick film procedure in D 5403 with a UV flexo black ink. This would probably be the worst case scenario since cure of black inks is most impacted by film weight and the flexo formulations contain greater levels of possibly more volatile monomers than lithographic inks. The group on Print Gloss heard that their procedure has been approved as a new standard, D7163, "Standard Test Method for Determining Specular Gloss of Printed Matter." R. Czarnecki is the interim Chair for the group on Blocking until a representative from INX joins the subcommittee. It was agreed that Blocking should be written as a practice, not a test method.

D01.57, Artists' Paints and Related Materials

M. Gottsegen, Chair

The group on Lightfastness of Pigments heard from M. Gottsegen, Chair, that the ballot on Draft 16 of the revisions to D 4303 "Methods for Lightfastness of Colorants Used in Artists' Materials" had received a negative that was found to be persuasive. A new draft will be balloted as a concurrent D01/D01.57 ballot. The Specifications group approved minor changes in Tables I of D 5067, D 5098, and D 5724; these changes will constitute reapproval of these standards. Further changes to these and other specifications are still pending the revision of D 4303.

W. Berthel, Chair of the Physical Properties group, reported that all of the sizes had been applied to the test canvases but that there were numerous problems applying the acrylic primers since they all behaved differently. He said that they had found critical variables, including stress and strain, rate of elongation, relative humidity, temperature, age of sample, effect of resin, and composite dynamics. He reported that a rapid test shows more stress and brittleness than a slow test, that humidity makes a striking difference possibly from swelling of the polymers in the gesso, that acrylic gessoes are stiffer at low temperatures, and that strain increases with age.

W. Stopford M.D., Chair of the Toxicity Determination group, reported that he was dealing with Health Canada on their new CCCR regulations which had been revised to be more like those in the U. S. but which covered only acute hazards. He said that he would be asking them to refer to or implement three standards: D 5517, D 4236, and D 6801 (auto-combustibility). He also reported that CPSG had issued a draft Arts & Crafts Safety Guide. The Pastels group Chair V. Elliot agreed to modify the proposed standard in conformance with changes proposed for D 4303, and that he would accept the help of M. Mizen. There was no report from I. Garrett on possible solutions to the sample preparation problem.

D01.61, Paint Application Tools

J.D. Feathers, Chair

T. Sliva, Chair of the Paint Brushes group, distributed copies of the new "Standard Guide for Application and Evaluation of Brush and Roller Applied Paint Films." The item has completed society balloting and was designated as ASTM D7073-05. This guide was developed for laboratory personnel, giving them both guidance in application procedures and techniques for comparing coatings of similar color. The chair reviewed the status of the task group and the methods under its jurisdiction. Future directions of the task group were discussed. The chair announced he is stepping down and a volunteer for chairing the task group was sought. The chair is currently soliciting ideas on methods for attributes of brush parts that could be used to verify differences in quality, new practices involving brushes for use by laboratory personnel and other suggestions for the future direction of the task group.

The group on Paint Rollers reviewed results of the most recent round robin testing of the proposed method for "Fiber Shedding of Paint Roller Covers," Work Item WK6749. There was some variability in defect identification among lab cooperators. Pictures showing different possible defects will be added to the method to clarify defect definition. Another round robin will be conducted with these method changes. The current method Appendix will be expanded and changed to a method Annex since it contains mandatory information that can affect results.

The Knitted Paint Applicator Fabrics group reviewed draft #6 of the proposed "Practice for Physical Characterizations of Sliver Knitted Paint Applicator Fabrics." Additional changes were suggested to make the practice applicable to different sample sizes. While a method for measuring fabric tensile strength is still under development, it was decided that a round robin test could be done on the shearable pile height and shearable pile density segments of the practice. This will be attempted before the January 2006 meeting.

The group on Definitions & Nomenclature reported that the 42 previously proposed terms related to paint applicators has been reduced to 25 terms. These terms will be submitted via e-mail to task group members for a group ballot by September 1, 2005, with progression towards a subcommittee ballot by the end of the year. Results of balloting and comments will be discussed at the January 2006 meeting. The Fracture Resistance group reviewed the latest draft of Work Item WK6755 proposed method for "Testing Fracture of Level Paintbrush Filaments." This draft incorporated editorial changes suggested at the last meeting. This method has been submitted for subcommittee balloting in July.

In the D01.61 Subcommittee meeting, the chair recognized Tom Sliva of DL Laboratories for his many years of service in the task group for Paint Brushes. He is stepping down from his TC chair position due to his heavy involvement in other D01 activities. Under his guidance, this task group published many new practices, guides and methods for the paint applicators industry. Darryl Kaminski of Shur-Line has agreed to become the new chair for this group.
