ASTM Committee D01 reports on January 2006 subcommittee activities.
There was an excellent Technical Seminar on "Statistics and Standardization" that had been initiated by Bill Golton, Chair of D01.15, Meetings and Symposia, and co-organized by Robert Morrison, Chair of D01.20, on Quality and Statistics. The three speakers, R. Morrison, T. Brooke, and Lou Asher each did an excellent job of making statistics interesting. Their topics, "Statistics Tips and Traps," "ASTM Interlaboratory Study (ILS) Program Overview," and "The Use of Ranked vs. Rated Data in the Evaluation of Weathered Specimens," respectively, provided much useful information.
D01.08 on Environmental Concerns heard news of a new South Coast Air Quality Management District rule for coatings (SC1113) that introduces more stringent requirements for a number of coatings that will take effect in 2006-2008. The Ozone Transport Commission, a consortium of Northeastern states ranging from Virginia to Maine is considering adoption of SC1113's provisions. Subcommittee 21 on Analysis of Paints had a number of meetings on methods for measuring VOC and HAPS. About 75% of the activities of D01.21 now are environmentally related. D01.23 on Physical Properties of Applied Paint Films discussed adhesion methods, revisions to the new practice D7091 on dry film thickness, abrasion resistance by Taber Abraser, contact angle measurements, and mar/scratch measurements by nanoscratching. D01.28 on Biodeterioration reported that WK8681, "Determination of Resistance to Mold Growth on Interior Building Products in an Environmental Chamber," was ready for balloting.
Subcommittee 34 on Naval Stores continued to work on a method for determination of neutral content of tall oil fractions and reported on the campaign to convince FDA and the Food Chemical Codex to replace the USRG color scale with Gardner colors in their regulations on rosins. D01.45 on Marine Coatings met separately from D01 in West Bethesda, MD. This very active subcommittee discussed many methods and topics, including measuring of release rates of organic biocides from antifouling coatings, an exposure practice for testing antifouling panels, coating aging and drag measurements, and copper release rates. The members of the group work closely with their ISO counterparts and Mr. A. Finnie received a Certificate of Appreciation from D01 for his leadership in coordinating activities between the two organizations. Another active and enthusiastic subcommittee, D01.46 on Industrial Protective Coatings, discussed methods on surface preparation, surface roughness of concrete, solvent resistance by solvent rubs, adhesion of coatings on concrete, graffiti resistance, and revisions to D6577, "Guide for Testing Industrial Protective Coatings." The revision of D3276, "Guide for Painting Inspectors (Metal Substrates)," will be published soon.
DIVISION 1 ADMINISTRATION
D01.06, International Coordination and US TAG to ISO/TC35
T. Sliva, Chair
The Chair reviewed ballot actions since the June 2005 D01.06 meeting for ISO TC35, Subcommittees SC 2 on Pigments, SC 9 on Paints, and SC 10 on Varnishes. The chair reported on a conference call with selected members of ISO on November 17 to discuss ways to implement the actions outlined in the Memorandum of Understanding signed between ASTM D01 and ISO TC35/SC9. The other purpose was to improve communications between liaisons and their respective ISO Working Groups, including expanded access to electronic e-balloting and document retrieval. The second meeting of this group is planned for February 15. A proposal has been introduced to form a joint working group between ISO and ASTM on Volatile Organic Content methods. The convener of Working Group 27 on Determination of Leaching Rates from Anti-Fouling Paints, Mr. A. Finnie, was recognized with a Certificate of Appreciation by D01 for his work in Subcommittee D01.45 on Marine Coatings and his coordination between D01.45 and ISO at their meeting in Washington, D.C.
D01.08, Environmental Concerns
J. Berry, Chair
D01.08 is a point of contact for ASTM, Federal, and State agencies. It helps coordinate the testing needs of agencies with analytical talents within D01. It also provides a forum for the presentation and discussion of environmental programs and issues. In January, it had a joint meeting with Task Group D01.21.13 on Coordination of VOC/HAP Method Development.
B. Golton reported on activities within Subcommittee D01.21 on Chemical Analysis of Paints, noting that about 75% of its activities now are environmental-related. A number of task groups are working on VOC and HAPs methods and efforts are being made to harmonize ASTM methods with ISO methods. The test being developed to allow rapid determination (5-10 minutes) of non-volatile content is near complete. The test will be ideal for use to assist in manufacturing quality control, but must first be correlated with ASTM 2369 to provide an effective means for ensuring coatings are compliant with environmental regulations.
D. Salman, U.S. EPA, explained that the Clean Air Act required the EPA to develop air pollution standards for hazardous air pollutants (HAPs) that require application of the "maximum available control technology" (MACT). Within a specified time after such a regulation (of which perhaps regulations for 100 industrial categories were promulgated over a 12 year period), an analysis must be made to determine if MACT reduced risk to an acceptable level. If not, more stringent restrictions must be enforced, up to and including closure of the source of emissions. Mr. Salman pointed out that perhaps a dozen MACT rules apply to coating sources. Only one magnetic tape manufacturing facility remains in this country, so residual risk from its emissions is acceptable. Methyl ethyl ketone has been removed from the Agency's list of HAPs.
D. Darling of NPCA reported that the South Coast Air Quality Management District (SCAQMD) of California has a new rule (SC1113) for coatings that introduces more stringent requirements that will take effect for a variety of coatings from 2006 to 2008. He said that the NPCA is working to have South Carolina follow the federal government and declare tertiary butyl acetate not to be a VOC. The "Ozone Transport Commission" (OTC), a consortium of Northeastern states ranging from Virginia to Maine that was formed to work jointly to reduce ozone appears set to adopt the provisions of SC1113 for the entire region by 2008 or 2009. The OTC proposes to conduct a survey of coating manufacturers for sales information similar to a previous study by the California Air Resources Board (CARB). CARB will revise its suggested control measures this year and is also considering adoption of SC1113's provisions. Every entity seems to be moving toward adoption of the most stringent regulations.
E. Praschan, a member of the EPA's "Environmental Technology Verification (ETV)" steering committee, reported that the Agency seems to have lost funding for that program designed to provide third party verification of performance claims by vendors of coating materials and application technologies intended to reduce air pollution. Subcommittee D01.55 on Factory Applied Coatings for Preformed Products is developing an ASTM Guide or Practice based on the ETV test protocol for coatings.
Since the meeting, as a consequence of a survey to the attendees for recommendations on how to improve the value of D01.08, additional speakers have been invited to the June meeting. Environment Canada will provide a summary of its plans for new coatings regulations. Also, the Executive Director of the Ozone Transport Region has been invited to share the group's plans.
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 have been calling this session a "mini-symposium" for a number of years. The program scheduled for January 24, "Statistics and Standardization," was well received by an audience of about 70 people. Speakers Robert Morrison, Louis Asher, and Tim Brooke did an excellent job of making statistics interesting. The chairman was disappointed that three subcommittees had scheduled meetings during the time scheduled for the lectures. A plea was made at the Executive Subcommittee for recognition of the need to not compete with programs at future D01 meetings.
On behalf of the ASTM staff, Tim Brooke requested that we call our annual lectures something other than a "mini-symposium." It seems that the appearance of the word symposium in the title was causing confusion at headquarters! It was agreed to adopt the term "D01 Technical Seminar" for future programs. It was decided that the topic for the January 2007 D01 Technical Seminar would be Recent Developments in Accelerated Weathering. Committee G03 on Weathering has agreed to cosponsor the program and their Chair, Warren Ketola, will work with this subcommittee to ensure a successful program.
J. Bryson, Chair
There were negatives on each of the following balloted definitions:
* 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. M. Skalka noted that the classification of an oil does not depend on application thickness. The following definition will be considered:
drying oil, n -- an oil that, when exposed as a film to air, will oxidize and polymerize into a strong, flexible, cured film.
DISCUSSION: Most drying oils are principally glycerin esters of di-unsaturated and tri-unsaturated fatty acids.
* crawling: The wrong definition was balloted; it received numerous negatives. Bryson found that there is one definition in use for wet coatings, and a different one for over caulk. A revised definition will be screened and balloted.
* tint, v -- to confer a small level of color to a coating formulation. E. Carter said that "colorant" should be used in place of "color," and noted that E 284 has a different definition. The following definitions will be considered:
tint, v -- 1. to mix a white paint with a colorant or colored paint, or to mix a colored paint with a white pigment. 2. to adjust the color of a test specimen to be a closer match to the standard (E 284).
* paint, n -- general, a pigmented (liquid or paste) coating material, or a coating resulting from the application of such a material.
M. Skalka noted that a binder is needed. E. Praschan noted that there is no provision for clearcoats or varnishes, and felt that this definition should include powder coatings. The following definitions will be considered:
paint, n -- general, 1. a liquid, paste, or powdered coating material, containing binder, and typically containing pigment(s). 2. a coating resulting from the (typically uniform) application of such a material.
J. Bryson, Chair, will contact subcommittee D01.21 to work them to review the terms and definitions in D01.16 of interest to them.
D01.94, Awards and Memorials
T. Sliva, Chair
The Chair reported that the John C. Weaver Award of Excellence was presented to Paul Guevin for his outstanding leadership in Subcommittee D01.23 on Physical Properties of Applied Films and his coordination with ISO TC35/SC9, Working Group 23. Dr. Rey G. Montemayor was presented with the Henry A. Gardner Award as the Subcommittee Chairman of the Year for his work chairing Subcommittee 35 on Solvents, Plasticizers and Chemical Intermediates since 1992. Joseph Peters of the Leneta Company presented the Leonard Schaffer Memorial Award to Doug Grossman of Q-Labs for his leadership roles in both Subcommittee D01.27 on Accelerated Testing since 1990 and his role as liaison to ISO TC35/SC9, Working Group 26 on Performance Testing. Certificates of Appreciation were presented to Mr. A. Finnie for his work in Subcommittee D01.45 on Marine Coatings and his coordination of ASTM D01.45 with ISO TC35/SC9, Working Group 27. Dave Salman of the Environmental Protection Agency was recognized for his work in Subcommittee D01.21 on VOC methods and his coordination of work between ASTM D01 and EPA. Awards were presented to both Dwight Weldon and Robert Stachnik for their work in Subcommittee D01.46 on Industrial Protective Coatings.
L. Pattison, Chair
Unfortunately, ASTM is not considered to be an essential part of corporate business packages. CEOs, VPs, and managers do not see ASTM as important to their business. Why? We need more participation, but people outside ASTM and even many new members are not sure what membership means or how to participate. We need to figure out how to promote D01. So far, we are not doing very well.
DIVISION 20 RESEARCH
D01.21, Analysis of Whole Paints and Paint Materials
H. Fujimoto, Chair
The purpose of the task group on ISO Liaison for VOC methods has been to report on the activities of ISO TC35 WG1 on VOC Methods. For several years J. Phillips had chaired it, but he has had to resign from his ASTM activities. G. Janezic has accepted an appointment in his place. Recently, Dr. Harald Nissler, convener of the ISO working group, formally proposed a joint working group between ASTM D01.21 and ISO TC35 WG1, to work together on VOC methods. He pointed out that since most of the new methods for VOC in both organizations are based on gas chromatography and are very similar, it is logical to coordinate the work and as much as possible, adopt common methods for the use of paint companies and their suppliers and customers and regulatory agencies worldwide. The group responded positively and, therefore, was designated as the one to work with ISO on VOC methods. Its new purpose will be to coordinate VOC method development with ISO in a way that minimizes duplication so that international consensus standards will be available for measurement as much as possible. G. Janezic and H. Nissler will be listed as cochairmen of the joint activity. This will not preclude other joint activities on specific methods, such as the current collaboration on a headspace-GC method for low VOC water-based paints.
The group on the Clarification of EPA Method 311 provides feedback to the U.S. EPA on their Method 311 for HAPS in coatings. R. Nelson has retired as chair and has been replaced by his NPCA successor, D. Darling, who provided the group with an overview of the Method 311 Round Robin work completed by NPCA back in the summer of 2003. The intent of the study was to identify the precision limits for the method. Unfortunately, not enough samples were tested to develop proper precision limits. M. Wills took the data and wrote a report for the task group that was received in 2004. A further goal of the group was to have him publish an article in a trade magazine informing the public of the results of the Method 311 Round Robin. Because of concerns over the results of the study (specifically, repeatability results ranging from 2% to 19%, reproducibility 5-157% for individual HAPs tested and 8-34% for total HAPs), NPCA and other coating application industries were very concerned with the precision results for Method 311 Round Robin. Therefore, Prof. Wills was asked to delay developing an article until the ramifications of the article and the results of the Round Robin could be analyzed, especially considering that Method 311 would be used to determine HAP content of coatings in compliance situations. Further concerns were raised over rumors that certain states were getting ready to run Method 311 on surface coatings for compliance purposes. Upon further review, NPCA decided to send EPA a letter requesting a meeting to discuss problems with Method 311 and discuss possible solutions, including possible "safe harbor" language in case of a compliance situation where there was a difference between formulation and Method 311 test data. The task group concluded that further discussions on ways to improve the Method should occur at the next meeting in Toronto.
The Rapid Nonvolatile Determination Group met under the leadership of K. Leavell. The main purpose of the meeting was to cover the negatives and comments from a recent main and sub-committee ballot. A number of changes will be made and the method (WK 3882 "Standard Test Method for Rapid Determination of the Nonvolatile Content of Coatings by Loss in Weight") will be reballoted. The importance of this method is the short time that it takes to run. It is much more rapid than other methods and should be useful for QC measurements.
The group on GC Analysis of Specific Volatile Components has jurisdiction over three methods, D6133, D6438, and D6886. Chair M. Wills reported that a new Agilent 6890 GC/MS/FID system, including a Model G1888 Headspace Sampler, has been installed at California Polytechnic State University and has been tested with several coatings. A number of the 28 coatings analyzed for NPCA/SCAQMD's rule 1113 assessment in the fall of 2005 using ASTM Method D6886 on an older HP 5890 GC system have been analyzed with the new system and were compared with results obtained using ASTM Method 6886 on the older GC system. In our hands, the static headspace system gives excellent results for the speciated VOC content of the waterborne coatings that have been analyzed to date. We have tested a modification of Method 6886 in which the solvent used for analyzing coatings is water instead of tetrahydrofuran. The use of static headspace shows promise for the analysis of two-component systems and appears to give VOC content results which are nearly the same as those expected by EPA's Method 24 for total volatile content (ASTM Method 2369).
The group on Headspace GC Method for Low VOC Levels in Waterborne Products discussed the ASTM-ISO VOC Workgroup and how it pertained to the development of a headspace GC method for low VOC waterborne products. It was noted by Chairman Linder that the EPC and EPDLA position was that a joint ASTM-ISO VOC workgroup would provide a forum for bringing together representatives from ASTM and ISO that are working on developing analytical methods for measuring VOC in waterborne materials. The short-term goal of the joint VOC workgroup would be to enhance the sharing of information to develop reliable VOC analytical methods deemed acceptable for regulatory compliance. The long-term goal would be a harmonized method acceptable in North America and Europe (noting that differences in VOC regulatory programs complicate the establishment of a common method). B. Golton pointed out that D01.21.16 had been formed to address many of these issues and mentioned the memorandum of understanding (MOU) between ISO and ASTM. Chairman Linder expressed his opinion that the headspace VOC method was outside the scope of the MOU because the headspace GC method is specifically targeted at the U.S. regulatory definition of VOC which is very different from that in Europe. It was noted that the group was exemplary in its cooperation with ISO colleagues.
Chairman Linder next presented an update of the work currently being done with the headspace VOC method. Reproducibility needs to be improved, and a number of experiments were carried out to identify the cause and/or remediate the lab to lab variability. Experiments were carried out to better understand the effects of retention gap type, vial pressurization time, vial pressurization pressure, loop fill time, and water content. Although revisions were made to the method to address these findings, it was concluded that there was still a problem with reproducibility. New additional experiments have uncovered retention (adsorption) of alcohol components (including the previous 2-butoxyehtanol standard) in the headspace instrument contributed to low recoveries and poor reproducibility. Large instrument to instrument variability for various compounds was noted which was related to the inertness of the headspace auto sampler. It was noted that the use of Silicosteel[R] headspace components greatly improved problems with undesirable retention of various alcohols by the headspace system. Chairman Linder outlined current plans for an interlaboratory study with a test mixture designed to characterize the inertness of different laboratories headspace instruments and plans to adjust conditions to minimize problems with undesirable retention of volatiles such as alcohols. It was speculated that some similar procedure could be incorporated into the method to qualify the inertness and suitability of instrumentation for this analysis.
The group on Water Content by Calcium Hydride Method did not meet, due to the absence of Chairman Lynn. However, he sent an update on developments related to the method plus a copy of the latest version. HydroScout meters have been reprogrammed to have a dedicated program for the analysis of paint. The new method has been written for this version of the meter. Anyone who is interested can contact the Chair, who will send them a meter and some reagents. Those collaborators who already have older meters can send them back for upgrades.
The group on VOC Credit for Cure Water 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, and balloted several times. Results of the recent main committee ballot and the three negatives were discussed at this meeting. The three negative voters were contacted by e-mail answering their concerns and comments prior to this meeting. At the time of the meeting there was no reply from the individuals who voted negative. The task group then proceeded to discuss and vote on the negatives separately. One of the negatives was based on the lack of an adequate precision and bias statement and was upheld as persuasive. The Chair mentioned there was enough data available to develop a precision statement for repeatability. A round-robin needs to be carried out to provide reproducibility data.
The group on the Revision of D3960, "Practice for Determining Volatile Organic Compound Content (VOC) of Paints and Related Coatings," met to discuss the latest revision, which includes noting that t-butyl acetate now is VOC-exempt. Appendix X3 was rewritten, in order to simplify it and to bring references up to date. Certain organic compounds that may be released under the specified bake conditions are not counted toward coating VOC content because they do not participate appreciably in atmospheric photochemical reactions. Such negligibly photochemically reactive compounds are referred to as exempt volatile compounds in this practice. D3960 undergoes constant revisions in order to keep the method up to date whenever new exempt volatiles are approved and when new methods are approved that are appropriate for inclusion in D3960.
The scope of the Exploratory Analytical Research group is to review new or needed test methods, ascertain whether proposals made to the Subcommittee 21 have merit and deserve further study and/or consideration, recommend formation of new task groups and address any major problem facing any of the task groups. T. Schwedt, Texas DOT, is using ASTM D3168, Qualitative Identification of Polymer in Emulsion Paints. He would like to bring the techniques used in the method up-to-date. The group decided that since the method is used widely, nationally and internationally, it would be better to insert a Method B at this time. At the next method review in five years, the TG can decide to drop or retain Method A. The proposed Method B will be submitted at the next meeting. If needed, a mini-round-robin will be set up to compare and to review the results.
Two years ago, a test method for Volatile Content of Fast Cure Multicomponent Paints was revised after Sub. 21 Ballot and approved for simultaneous Sub. 21 and D01 ballots. Somehow the method was never reballoted. The oversight has been noted and the method submitted for approval. F. Gelfant proposed that some changes be made to the method. The group decided it would be more appropriate to get the method approved, as written, and then make any needed changes. Otherwise, its approval might be delayed for years. Mr. Gelfant will distribute his proposed changes and if needed, a round robin will be set up to test the proposed changes.
D01.23, Physical Properties of Applied Paint Films
P. Guevin, Chair
G. Nelson, Chair, reported to the group on Adhesion D3359, "Measuring Adhesion by Tape test" is referenced in over 75 other ASTM standards. Among other committees, B08 now has a test method, B905, which assesses the "adhesion of metallic and inorganic coatings by the mechanized tape test." Committee F01 has a test method, F1842 "Test Method for Determining Ink or Coating Adhesion on Plastic Substrate for Membrane Switch Applications." This method uses a mechanical device to remove the tape at a regulated, uniform rate and constant angle while simultaneously recording the removal force. After discussion, it was decided to add D6691, "Standard Test Method for Measurement of Internal Stress in Organic Coatings by Cantilever (Beam) Method" to the methods overseen by the group.
The very active group on Dry Film Thickness discussed the new practice D7091 and the negative on the ballot on the addition of a second Appendix. Chair A. Freidenfelds indicated the reason an additional Appendix was drafted and submitted for ballot was because of the need to separate and clarify the two types of gauges referenced (Type I and Type II). The original Appendix referenced both and there were concerns that it would lead to misunderstandings. After much discussion, it was decided that the task group would rework the new Appendix and circulate it for opinion among the equipment manufacturers before re-balloting. The group voted to withdraw dry film thickness methods D1186 and D1400 and replace them with practice D7091. A discussion followed regarding D4138, "Measurement of Dry Film Thickness of Protective Coatings by Destructive Means" and whether the group was willing to accept it from Committee D33. A vote was taken and it was decided to accept D4138.
The group on Hardness, Scratch and Mar Resistance discussed the revision of D968, "Test Methods for Abrasion Resistance of Organic Coatings by Falling Abrasives," which will be revised editorially based on comments received. Most of the meeting was spent discussing the negative votes from R. Boni and T. Schwerdt on the revision of D4060, "Test Method for Abrasion Resistance of Organic Coatings by the Taber Abraser." It was the consensus that their rationale was persuasive and the necessary changes will be incorporated and the method will be placed on the next ballot. Chair P. Guevin reported receiving a question on the use of the Elcometer 3086 Motorized Pencil Hardness Tester to perform Test Method D3363, "Test Method for Film Hardness by Pencil Test." After much discussion on the merits of such a device, it was agreed that there were too many manufacturers of this type of instrument in the world and we should not revise Test Method D3363 to support its use.
The Contact Angle Measurements group heard a short presentation from C. Schoff on the use of contact angles to measure the wettability of surfaces and to determine solid surface tensions and their dispersion and polar components. He handed out draft methods for measuring contact angles and solid surface tension. The latter could and possibly should be added to the basic contact angle test method. There was considerable discussion and a number of suggestions were made for improvements to the contact angle test method, including expanding the significance and use section and adding a number of explanations and caveats as to timing of measurements and other potential problems.
The Scratch/Mar Resistance group met to discuss the results of the ballot of the proposed "Test Method for Measuring Mechanical Aspects of Scratch/Mar Behavior of Paint Coatings by Nanoscratching." Due to a persuasive negative vote, the method was removed from the ballot until statistical studies have been completed and a revision made. At the meeting, Tom Sliva presented the William T. Pierce Award to Dr. Li Lin for his work on mar and scratch resistance measurement, particularly for his paper "Quantitative Characterization of Scratch and Mar Behavior of Polymer Coatings."
The Exploratory Research group discussed the negative vote on the proposed "Test Method for Measurement of Internal Stresses in Organic Coatings by Cantilever (Beam) Method." The voter wanted the group to amend the scope to embrace all coatings. When it was explained to him that this proposed test method was designed for radiation curable coatings and, when proven, powder coatings, the voter withdrew his negative. The test method has been assigned the number D6991 and will appear in the 2006 Annual Book of ASTM Standards.
D01.24, Physical Properties of Liquid Paints and Paint Materials
C. Schoff, Chair
The group on Dispersion Phenomena discussed the possibility of developing a guide on identifying flocculation in paint. There were concerns that merely identifying flocculation was not necessarily useful and that quantifying flocculation was very difficult. The group decided not to proceed with the guide. The main project of this group has been to separate dispersion methods from color, tint strength, opacity or other evaluation methods. Historically, D01 methods have lumped these together. The first dispersion method is D6619, "Practice for Incorporating Pigments by High Speed Disperser." The next method would be for use of a miniature sand mill (currently now in D01.26 practice D3022 coupled with opacity measurement), but there is an ISO method that provides that information. Chair R. Morrison is working toward acceptance of the ISO method and having D01.26 write a new document on opacity. A method for dispersion by muller probably will follow.
The Viscosity Methods group discussed (1) Efflux cups--A question has been asked as to the need for or desirability of the shaker conditioning step in D1200 Ford Cup. A note will be added to indicate the pluses and minuses of shaking. Shaking will be made non-mandatory. (2) Rotational viscometers--There is interest in developing a cone/plate viscometer method for measurements at 500 sec[.sup.-1] for the auto industry and its paint suppliers. In addition, a number of paint viscosity measurements are being done at low to moderate shear rates (0.5 to 200 sec[.sup.-1]). We will work on a method or methods covering both ranges. Interest also was expressed in writing a method for a procedure in current use in industry to measure viscosity with spindle viscometers at 0.3 rpm. This will be considered.
The group on Electrical Resistivity discussed the need for revision for D5682, "Electrical Resistivity of Liquid Paints and Related Materials." The method was reap-proved in 2002, but is out-of-date with respect to many ASTM rules and guidelines and needs to be revised. Another group considered negatives and comments resulting from the most recent ballot on the revision of D5201, "Practice for Calculating Formulation Physical Constants." Corrections had been made and the need for more was found during the meeting.
D01.26, Optical Properties
N. Barnes, Chair
The group on Color, E. Carter, Chair, discussed the proposed Standard Guide for Evaluating Color of Semi-Transparent Wood Finishes, which has prompted discussions in the past, but little action. At the moment, there is no one willing to really pursue it.
Work Item #3714 "Proposed Guide Protocol for How a Supplier and Customer Set a Color Specification for a Material" is progressing well with only a few changes needed. The Hiding Power group discussed the use of drawdown charts from different suppliers. It was agreed that any methods should note that Leneta charts were used for the precision and bias statements.
The main topic of discussion by the group on Tinting Strength was the splitting of the dispersion techniques from the test methods. The dispersion sections will be written up as new methods by D01.24. It was suggested that we begin work on the color and masstone standards now. We will add the references to the dispersion standards when they are completed. During the meeting of the subcommittee, a presentation was made by R. Harold and P. Gossen on "Standard Test Method for Determining Fluorescence Instrumentally for the Application to Ballast Tank Inspection." There has been a lot of work within E12 on deriving a specification for the light source to be used for inspection. It was agreed to start a new task group on Fluorescence. P. Gossen is to write a standard for this application and present it at the June meeting.
K.P. Roberts, Chair
P. Hargrove, Chair, led the New Environmental Chamber Method group through the remaining portion of the draft for the new environmental chamber method. The discussion began at Section 14, where the group had left off. The discussion points focused on samples of non-standard sizes, such as banister spindles, representative negative controls and the grading scale. The group agreed that microscopic readings should only be done to confirm a clean surface rating of "10". The revised proposed new method will be submitted for balloting.
The group on Revision of D3274, "Evaluation of Fungal Disfigurement of Paint Films," discussed draft #5 of D3274 and results of the recent ballot on it. The negative vote submitted by K. Mearig argued that the rating scale is not an improvement over the current one and recommended a rating scale that is proven to be repeatable and reproducible. He also argued that there is no need for ratings between 0.03% and 1%. It was the opinion of the subcommittee members that the 10-0 scale was correct and that these building ratings can be differentiated by people who have experience with the lower level differentiation. The negative later was found non-persuasive by Subcommittee D01.28. Two other negative ballots from T. Schwerdt and L. Wienert are being reviewed by Chair, M. Crewdson, to determine if the issues in conflict can be resolved.
DIVISION 30 PAINT MATERIALS
D01.31, Pigment Specifications
G. Peake, Chair
G. Peake reported to the Titanium Dioxide group that D3925, "Test Methods for Percent Solids in Titanium Dioxide Slurries," is now published with the new method C included. Bob Hopkins of Millennium Inorganic Chemicals will be the new technical contact for this method. D3720, "Ratio of Anatase to Rutile in Titanium Dioxide Pigments by X-ray Diffraction," was reapproved and now has a 2005 date. D476, "Classification for Dry Pigmentary Titanium Dioxide Products," was reapproved and now has a 2005 date. No other standard activity was needed. R. Hopkins pointed out that in the future there may be a new grade of titanium dioxide with less than 80% TiO[.sub.2] content. In that case, we may want to revise D476 to include that new grade. No action is needed at this time. This may come about in the future and we just need to be aware, so that if we do consider changes to D476 we can notify interested parties to assure that they attend meetings.
The subcommittee reviewed progress on overdue standards. Action had been completed on most of the 1999 standards. D50 and D3720 were reapproved without change, D85, D210, D263, D3721, D3722, D3872, and D3926 were revised and approved; and D261 and D262 were withdrawn. D185, "Coarse Particles in Pigments, Pastes, and Paints," and D283, "Chemical Analysis of Cuprous Oxide and Copper Pigments," are still in urgent need of review. The two 2000 standards that needed review, D476 and D520, have been reapproved without change.
D01.34, Naval Stores
J. Russell, Chair
J. Russell, Chair, reported to the group on Determination of Neutral Content 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. Since the last meeting, a new sample of tall oil fatty acid had been distributed so that interested workers could compare results and comment on the method. Three out of four workers got reasonably good agreement for the level of neutrals of about 1.3% to 1.6% whereas one worker got results below 1%. It was pointed out that all these results were well below the level to be expected as the unsaponifiable content, measured by the standard wet method gave a value of 2.7%. Other comments suggested that the method as developed was too labor intensive for a QC situation as it required close attention for several hours. J. Harrison said that he had tried to simplify the method by converting it from a column method to a batch method. All participants agreed to participate in an evaluation of this method and report their results to Chairman Russell by the end of March.
The group on Color of Rosin and its Derivatives heard a report on the status of this project, the goal of which is to have the FDA and the Food Chemical Codex (FCC) change the wording of their regulations covering the use of rosin to reflect that the industry now uses Gardner colors and not the USRG scale. It was originally decided to amend the specifications of the rosin derivatives listed in the Food Chemical Codex prior to approaching the FDA. J. Russell reported that little if any progress had been made. The recommended path of first going to the Food Chemical Codex had proved to be unsatisfactory as no review or action had been taken by that group. So the plan had recently been changed and now the approach is to go directly to the FDA. In the course of this work it was realized that ASTM D509, "Grading Rosin," also needed updating as it did not include a procedure for sample preparation when using the Gardner scale. J. Russell made a proposal and this was discussed in detail. Several changes were agreed to and the proposed procedures will be used in a round robin currently being organized by ISO TC35/SC10/WG5, Naval Stores.
D01.35, Solvents, Plasticizers & Chemical Intermediates
R.G. Montemayor, Chair
A number of standard test methods and specification under the responsibility of this subcommittee will be reviewed and revised to include reference to ASTM E29 "Standard Practice for Using Significant Digits in Determining Conformance to Specifications" and ASTM D5386 "Standard Test Method for Color of Liquids by Tristimulus Colorimetry." 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.
Table 1 (next page) summarizes the standards that are being reviewed and revised, and then will be balloted concurrently at D01 and D01.35 levels this coming semester.
D01.37, Ink Vehicles
D. Weisel, Chair
The group on New Membership discussed poor attendance and the difficulties in attracting new members for the subcommittee. Consolidation, reorganization, restricted travel, and tight budgets continue to limit attendance. Industry professionals are willing to assist in round-robin testing, but cannot attend meetings. NAPIM will continue to contact members, but better follow-up is needed. The Resin Solutions group discussed the revision of D5958, "Practices for Preparation of Oil-Based Ink Resin Solutions." Editorial changes will be made and the availability of standard oils confirmed and the list updated. The group on Rheology of Ink Vehicles discussed WK8333, "Proposed Method for Viscoelastic Properties of Paste Ink Vehicle using an Oscillatory Rheometer" and results of a recent ballot. Changes will be made and the method will be submitted for D01 ballot. Other standards being developed in this subcommittee include a guide for printing ink vehicles, revision of the method on resin/solvent compatibility by precipitation temperature, and a new method on thermal stability of energy cured vehicles.
D01.38, Hydrocarbon Resins
J. Bryson, Chair
J. Bryson, Chair, noted that the term "hydrocarbon resin" and its definition have been approved. A revised version of D6493, "Softening Point," has been published. The Instrumental Color Determination group heard that N. Barnes had made Gardner color solutions in the 0-1 range. The x,y values for these solutions fell on a nearly straight line. He then had glass standards made to match the x,y values of these solutions as measured in 20-mm cells when zeroed against deionized water. A set of glass standards is a lot more practical than a set of solutions. S. Mowry provided the Oil Cloud Point group with repeatability values for oil cloud point determinations. However, a steward for the draft method still is needed. The group on New Instrumental Methods discussed the revision of D6604, "Practice for Glass Transition Temperature by DSC," the revision of D6579, "Practice for MW Average and Distribution Determination by Size Exclusion Chromatography," and a new method (WK4709) on "TGA for Determination of Volatiles."
DIVISION 40 PAINT PRODUCTS APPLIED ON SITE
D01.42, Architectural Finishes
N. Rogers, Chair
The Water Repellency of Wood group heard a report from T. Sliva, Acting Chair, on the progress on the proposed revisions to ASTM D4446, "Standard Test Method for Anti-Swelling Effectiveness of Water-Repellent Formulations and Differential Swelling of Untreated Wood When Exposed to Liquid Water Environments," and the round robin that is currently underway. The group on "Wet Edge of Latex Paints" received a report from C. Hawkins, Chair, that the method will be revised prior to the June meeting to incorporate comments from the group. Volunteers are needed for a round robin that is being organized. Other standards being developed in this subcommittee include a practice for testing touch up properties, a guide to testing exterior deck coatings, and a method on low temperature application of latex paints.
D01.44, Traffic Coatings
P.R. Guevin, Chair
The Thermoplastics group heard a report from J. Britt on the status of his revision of D4960, "Test Method for Evaluation of Color for Thermoplastic Traffic Marking Materials." Nine laboratories participated in the round-robin study. The color of white and yellow plaques were measured. The test results were submitted to R. Morrison for statistical analysis. P. Guevin told the group on Traffic Marking Materials that he wanted the revision of D913, "Test Method to Evaluate Degree of Resistance to Wear of Traffic Paint," to include a method to measure wear using optical instruments. He will contact D. Kuniega for his input since this practice is very likely being done by PennDOT. D969, "Test Method for Laboratory Determination of Degree of Bleeding of Traffic Paint," will be reviewed by T. Schwerdt.
P. Guevin reported to the Night Visibility group that T. Wade had supplied internal (Potters Industries) round-robin data on the roundness of glass beads in accordance with D1155, "Test Method for Roundness of Glass Spheres," and sieve size in accordance with D1214, "Test Method for Sieve Analysis of Glass Spheres." These data will be analyzed using E691. T. Brooke agreed to work with him in this matter. T. Schwerdt expressed interest in a test method for roundness and sieve size using a single particle optical analyzer. It turns out that T. Wade has received a grant from the National Cooperative Highway Research Program to develop such a standard. Mr. Guevin will provide T. Schwerdt with contact information. G. Shea mentioned a need for an ASTM standard based on Dow's water wash off test method. He and T. Schwerdt will develop it into an ASTM standard. J. Britt offered to write a new standard on a procedure for field sampling of liquid traffic paint.
D01.45, Marine Coatings
E. Haslbeck, Chair
The January ASTM D01.45 meeting was held in West Bethesda, MD rather than with the rest of D01. Dr. A. Finnie was presented with an Award of Appreciation by Committee D01. His tremendous contributions to both ISO TC35/SC9/WG27 and to ASTM D01.45 were outlined. The award was made in the form of a plaque.
The group on Measuring Release Rates of Organic Biocide from Antifouling Coatings (Z9489Z) discussed the subcommittee ballot results. Technical edits were made and the method will be modified and then balloted concurrently at subcommittee and main committee levels.
The group on Rating Antifouling/Physical Coating Performance discussed D3623, "Testing Panels in Shallow Submergence" in considerable detail. The method was balloted at the main committee level. Two negatives and a number of comments were received. Technical issues were raised, too numerous to discuss here. After much discussion, it was decided that D3623 needs to be re-formatted entirely, and needs to become an "exposure practice" for just about anything that could be called "fouling-control" surface (whether that be a coating, a "surface treatment," a texture, pattern, etc.). G. Swain has agreed to generate a new draft of the method by late March, 2006. He will focus on sections 6.4 and 4.4, but an overall revamping is in order. An early April 2006 internet editing session would then be conducted. A subcommittee ballot of D3623 would follow. At that point, but not before, discussion of the two other panel-exposure methods (D5479 and D4939) would be postponed pending re-wording of D3623.
The group on ISO TC35/SC9/WG27 and D01.45 Interactions heard a report from A. Finnie on ISO coordination with ASTM summarizing the Nov. 2005 ISO meeting. The ISO group has several draft international standards out for ballot and these have been sent to D01.45 members for comment. Subcommittee members are urged to provide comments, with a particular focus on ensuring that the current ISO copper release rate has been fully harmonized with the ASTM copper release rate.
International Paint is drafting a position paper on behalf of industry partners of CEPE and NPCA on the use of rotating cylinder biocide release rate data for environmental risk assessments. Lab methods are believed to overestimate actual release rates in the natural environment. This has the potential to create problems if the data are used in risk assessment models, and then to set regulations without accounting for the large differences between rotating cylinder lab studies and in-situ measurements (which, it is believed, reflect more closely actual environmental inputs from in-service vessels). This difference between actual and lab methods has been documented in one study with the SPAWAR dome which was conducted on a ship in harbor. In order to better estimate actual use release rates, IP's position paper is proposing the use of a correction factor for lab data that is based on an analysis of both lab and in-situ data. It is proposed that the correction factor would be based on the difference ratio between the lower bound 95% confidence interval of the lab data and the higher bound 95% confidence interval of the dome data.
Other topics that were discussed included:
Coating Aging and Drag Measurements: G. Swain summarized his prototype dynamic tank method that exposes test panels (wide array of sizes) to flow conditions more like what might be seen on an in-service hull. The method allows one to evaluate coating aging, as well as measure hydrodynamic drag (the panel mounts are fitted with force transducers).
Biofouling Assessment: G. Swain also talked about a digital evaluation method for biofouling assessment. Essentially a digital photo of a fouled panel is taken. Then, a software program called Photo Grid lays 100 random points over that digital photo. Fouling occurring immediately under those 100 points is recorded by type (such as barnacle, tube worm, algae, nothing, slime, etc.). There were some questions and concerns expressed by the group--especially about epibiosis (bug on bug errors). Geoff will consider incorporating such a method as an appendix/annex (non-mandatory) to Method D6990--panel inspection method. Alternatively, he might choose to publish it as a stand-alone method. No deadline was suggested for this task.
Copper Release Rate--UNDS and European Regulations: Dr. Alexis Kaznoff and Mark Ingle of NAVSEA Code 05M visited for an afternoon discussion of lab and in-situ or inservice biocide release rate (especially copper). The Uniform National Discharge Standards (UNDS) process identified copper hull leachate as a "discharge of concern" from Department of Defense (DoD) vessels. NAVSEA (on behalf of the DoD) is currently in the process of negotiating a rule (limit) for this discharge.
The fact that ASTM D6442 and ISO 15181-1 & 2 typically result in release rates that are much higher than other release rate methods where measurements are taken from in-service vessels or harbor-exposed panels was discussed. The risks in using lab-derived data in risk assessment and to set regulations were also debated. The group decided that the D6442 wording should be modified to include more rigorous language in the "scope" and "significance and use" sections. The goal, in effect, is to warn against use of the ASTM method for environmental risk assessment and/or setting environmental regulations. A. Finnie volunteered to suggest wording changes. The changes would be balloted. Similar changes are envisioned for the relevant ISO methods.
D01.46, Industrial Protective Coatings
L. Smith, Chair
The Surface Preparation group heard a report from D. Weldon, Chair, that WK7945, "Measurement of Surface Roughness of Abrasive Blast Cleaned Metal Surfaces Using a Portable Stylus Instrument," had passed committee ballot and will be published as D7127. A round robin is needed to determine the precision and bias of the method. R. Stachnik presented plans for the round robin for Method C of D4417, "Field Measurement of Surface Profile of Blast Cleaned Steel." He reiterated the need for the testing as some of the data used to develop the precision and bias for coarse and X-course replica tape were outside their range of applicability. A written protocol for performing the round robin was handed out. L. Smith pointed out that the protocol required measuring the anchor profile in a marked location on each panel, while the other two methods in D4417 have precision and bias statements related to data collected randomly on the surface of the blasted steel. A decision needs to be made as to how the round robin will be performed. The precision and bias will relate to the difference between two operators measuring the same spot if the location is marked off, while the precision and bias statement will relate to the difference between two operators measuring the same surface if the spot was not marked off. The decision on whether or not to mark off the area was postponed until the next meeting.
It was pointed out that since blasted steel panels would be needed for the D4417 round robin, the round robin for D7127 should be performed at the same time on the same panels. A discussion ensued on the ability to pull everything together to run the round robin in February 2007. All that would be needed in terms of supplies are the blasted panels, replica tape kits, and stylus recorders. L. Smith and B. Corbett volunteered their companies to make the panels. Sources of stylus recorders would need to be identified. The preliminary assessment was that the round robin could be put together quickly. R. Stachnik, D. Weldon, and H. Roper volunteered to work on the plan for a combined round robin for D4417, Method C and D7127.
R. Stachnik asked if the data from the replica tape portion of the round robin could be shared with NACE International for inclusion in a revision of NACE RP0287, "Recommended Practice of Field Measurement of Surface Profile of Abrasive Blast-Cleaned Steel Surfaces Using Replica Tape." He pointed out that they present data in a different manner than ASTM. L. Smith checked with T. Brooke who stated that this would be acceptable as long as NACE cited the source of the data. L. Smith handed out a preliminary draft of a new "Practice for Indicating Oil in Abrasive." Comments made by the group included making sure that a clean container was used for each test, and requiring warm water. D. Weldon and H. Roper agreed to assist in developing the next draft of the document.
R. Glover gave a presentation on a method he has developed for measuring surface roughness of concrete. The procedure consisted of mixing a proprietary two-part putty and making a replica of the surface. The putty sets up in a few minutes. A specially modified spring micrometer is then used to measure the difference between high points and low points in the surface. The roughness range can then be quantitatively determined. There was a lot of interest in this method by the task group. The main concern expressed by the task group was the patent status and whether or not this subcommittee wanted to prepare a standard around a patented method. It was decided that R. Glover will provide L. Smith with information on the patent status of this method. Further discussion was postponed until the next meeting.
D. Allerton, Chair, reported to the Repainting group that D5402, "Practice for Assessing the Solvent Resistance of Organic Coatings Using Solvent Rubs," had received several negatives and comments on the Committee ballot. Three negatives were due to the use of the term "100% cotton cloth" with no explicit mention of cheese cloth. The intent was to allow both cotton cloth (as commonly used when testing industrial coatings) and cheese cloth (as commonly used by coil coaters). Therefore cheese cloth will be added to the description of materials. The document will be reballoted. F. Gelfant reported to the Adhesion group that the new Test Method for Pull-Off Strength of Coatings on Concrete Using Portable Adhesion Testers passed Committee ballot and has been given the designation D7234. A discussion was held on how to perform the round robin for this test. The main concern was whether one concrete or multiple concrete were used. F. Gelfant expressed concern about uniformity of the substrate if multiple concretes were used to form block to be coated, and suggested that one slab be poured with multiple coatings applied to it. Concern was expressed about having to ship the slab to multiple facilities for coating and testing. Task Group members stated that one company can apply all the coatings, and it would be worth considering having the slab at one location with testers coming to the slab. L. Smith stated that performing one round robin a year is about all the Subcommittee can handle, and the replica tape/portable stylus round robin will most likely get priority for 2006/2007. The Task Group should shoot for 2008 as a reasonable date. A task group was established to develop a test protocol for discussion at the next meeting.
L. Smith reported that everything was set for performing the round robin for D4541 the next week in Tampa, FL. He thanked the representatives from Ameron, Bayer Corp., CCC & L, KTA-Tator, Sherwin Williams Co., and Tnemec for preparing the panels. He informed the group that C. Mussler had emailed objections to the round robin based on the fact that it was going to be performed in a hotel room and that D. Beamish, an instrument supplier, was in charge. L. Smith pointed out that D4541 is a field method so location of where the testing can be performed should not be an issue. Nonetheless, he would check with ASTM staff and D01 officers, as this will affect the plans for the concrete pull-off test round robin. L. Smith informed the task group that no instrument suppliers will be allowed in the room when testers are performing their pulls. He reminded the task group that the data will be analyzed by ASTM, who will also prepare the precision and bias statement and generate the research report under the ILS program. He offered to take over by collecting the data sheets and submitting them to ASTM for analysis. The Task Group gave a vote of confidence to D. Beamish for his efforts to date in this round robin and in having him continue as the coordinator.
L. Smith, Chair, informed the group on Inspection that D3276, Guide for Painting Inspectors (Metal Substrates), passed Committee ballot, but received a number of comments. Many of the comments were editorial, but others were technical. The group decided to make the purely editorial changes immediately and issue the Guide.
The Testing Guide group heard that D6577, "Guide for Testing Industrial Protective Coatings," had received one negative vote and several comments on a recent ballot. The negative recommended that the guide should state that solar radiation is a main environmental condition that affects coating performance, which was found to be persuasive. Other negative comments made included combining sections on accelerated outdoor exposure, clarifying the use of filters for carbon arc accelerated weathering apparatus, and changes in wording to the description of xenon arc accelerated weathering apparatus. Changes will be made and the document will be resent for Committee/Subcommittee ballot.
The Graffiti Resistance group, D. Allerton, Chair, discussed the revisions made to D6578, "Practice for Determination of Graffiti Resistance." The most significant change was performing the tests for different cleaning agents of each marking material on one panel rather than on separate panels. This drastically reduced the number of panels needed. The washability tester was also removed and only manual rubs would be required. The rating scale was also altered to report gloss loss or shadowing. Both a qualitative and quantitative rating scale was presented. A discussion ensued on the solvents and quality of the solvents that should be used in the Practice. It was pointed out that there are proprietary solvent blends on the market used by professional graffiti removers that should be included in the Practice. In addition, the Practice currently references high-purity solvents that are really not needed. Commercial grade solvents are sufficient for this test protocol. A revised copy of the Practice will be sent for subcommittee ballot.
The group on Testing of Applied Coatings, heard from L. Smith, Interim Chair, that D01.46 had been approached by Committee D33 about taking over stewardship of three of their standards. These were D4138 on use of a Tooke Gage for measuring paint thickness, D4787 on continuity verification on concrete substrates and D5162 on holiday testing on metallic substrates. Prior to this meeting L. Smith had contacted the chairman of D01.23 about taking over D4138 as this appeared to be a more appropriate subcommittee. D01.23 agreed to accept this standard prior to the D01.46 meetings. Task group members voted to take over stewardship of D5162. However, no one present was aware of the underlayment material used in D4787 or of anyone who used the method. It was suggested that D33 be asked to ballot the item for withdrawal to see if anyone would step forward with a negative. If not, then either a new document will be developed using the wet sand bag method recommended by the holiday tester equipment manufacturers, or D5162 will be expanded to include this information in a general holiday testing Practice. Any decision on revisions to D5162 was postponed until the next meeting after D33 has informed D01.46 of the results of the ballot to withdraw D4787.
D01.47, Masonry Treatments
V. Huey, Chair
A new standard, D7089, "Practice to Determine the Effectiveness of Anti-Graffiti Coatings for Use on Concrete, Masonry and Natural Stone Surfaces by Pressure Washing" has just been published. The group on Water Vapor Transmission discussed the need to begin interlaboratory testing to develop a precision statement for D6490, "Moisture Vapor Transmission of Non Film Forming Treatments Used on Cementitious Panels." Publicity releases have been sent out to various coating journals, but there has not been much response. Anyone interested in participating should contact T. Sliva at 718-383-5080 or DLlabs@aol.com. Other standards that the subcommittee is working on include a practice for determining alkaline resistance on concrete and masonry and a method for measuring the effectiveness of field applied water repellent treatments.
D01.52, Factory Coated Wood Products
M. Foster, Chair
The subcommittee voted to disband it self. M. Foster will work with T. Brooke to place the standards that need to be maintained in other subcommittees and let the rest drop off as they expire.
D01.53, Coil Coated Metal
C.A. Gosselin, Chair
At the next D01.53 meeting, all the task group meetings and the subcommittee meeting will be scheduled concurrently during one time slot.
The group on Pretreatment of Substrates heard a report from J. Pierce who had been working on a Porta-spec method for the elements other than Cr and Ti (Zr, Mo, V) now common in pretreatments that are not currently covered by ASTM methods. C. Gosselin asked if there are other methods (e.g., in D01 or in G01) that may apply to the other elements and would save us from having to develop new standards. Mr. Pierce will review ASTM D01 and G01 documents for existing methods and report at the next meeting of D01.53. G. Peake reported on the recent history of D5723, "Standard Practice for Determination of Chromium Treatment Weight on Metal Substrates by X-ray Fluorescence." Several years ago a round-robin study was carried out to generate the statistics necessary to report precision and bias. The data indicated disappointing precision. No precision and bias statement was added and the standard has since been reap-proved (2002). However, a precision and bias statement will likely be required for the next balloting of D5723. In order to determine the next step, the results/report from that round-robin study must be reviewed by the committee.
J. Smith of Akzo Nobel will replace D. Cocuzzi as the Chair of the Accelerated Weathering group. At the June 2005 D01.53.03 meeting, the results of the 10-year weathering study were presented. The next step is to review the data and apply statistical analysis. J. Smith will review the data with D. Cocuzzi and, together with the task group, determine how to apply this additional analysis. C. Higginbotham is developing a wet-stack test method and suggested that it belonged in the Accelerated Weathering group. The group agreed. C. Higginbotham introduced M. Garrow of Valspar, who has been working with him on the method. She presented the committee with draft copies of the method for review. Members should forward comments to C. Higginbotham prior to June for discussion during the next meeting.
The Dry Film Thickness group heard a report from Chair J. Henderson on activity related to D 5796, "Standard Test Method for Measurement of Dry Film Thickness of Thin Film Coil-Coated Systems by Destructive Means Using a Boring Device." Data correlating the bore gauge results with an SEM referee method will be reviewed. J. Henderson and J. Smith will then organize a new round-robin study. The Solvent Rub Tester group discussed the need for a precision and bias statement and additional round robin testing for a new method for solvent rub testing (Z9405Z, "Test Method for Determining the Relative Resistance of a Coated Surface to Solvents using a Mechanical Rubbing Machine"). The standard will be reballoted with a precision and bias statement stating that the standard is new and precision and bias have not yet been determined. Task group Chair J. Henderson will put together a plan for the round-robin study and present it at the June meeting in Toronto.
G. Peake reported that The Shepherd Color Company has done experimentation aimed at determining the effects of coated panel parameters (substrate, primer thickness, topcoat thickness, topcoat chemistry, color) on the total solar reflectance (TSR) and emissivity of the panels. G. Peake will send a written version of the results to members of D01.53 prior to the June meeting in Toronto so that the results can be discussed for applicability.
D01.55, Factory Applied Coatings on Preformed Products
R. Polovich, Chair
The group discussed the revision of D333, "Guide for Clear and Pigmented Lacquers," and the negatives and comments on a recent D01 ballot. The suggested changes will be made in the document. Work Item WK5391, "Practice for Environmental and Performance Verification of Liquid Coatings," had been reviewed by several individuals and will be submitted for subcommittee ballot.
D01.56, Printing Inks
P. Ford, Chair
The Fineness of Grind group discussed results of the recent ballot on the revision of D1316, "Fineness of Grind by the NPIRI Grindometer," which received several comments and a negative. The negative was in response to the inclusion of an automatic drawdown machine in the revision. The voter was concerned that the referenced instrument would change and no longer fit the standard. The negative was voted non-persuasive since the method was written for a commonly used piece of equipment and any future developments in it can be accommodated in future revisions.
J. Fetsko revised D2066, "Relative Tinting Strength of Paste-Type Printing Ink Dispersions," to include preparation of the bleaches on a Flacktek mixer. She also provided for an alternative weighing procedure where the exact weights are used rather than adjusting the weight of the bleaching white to compensate for a slightly different actual weight of the ink. In addition, she included a reference to using a fan to cool the mixer in order to achieve more rapid, more complete mixing by maintaining the viscosity of the bleach.
Proposed method WK 1735, "Relative Cure of Energy Cured Inks and Coatings," received a negative on a recent main committee ballot. The negative was based on the fact that the method did not provide any definitive information on the amount of unreacted material remaining. The subcommittee found this negative to be non-persuasive since the method is designed for relative cure and this is defined as being related to end-use performance rather than chemical composition. Recently published new and revised standards from this subcommittee include D7188, "Terminology for Printing Inks, Materials and Processes," D7189, "Relative Mileage of News Ink on Newsprint," D4040, "Falling Rod Viscometer," D6531, "Tinting Strength of Liquid Inks," and D6419, "VOC of Sheetfed and Coldset Inks."
D01.57, Artists' Paints and Related Materials
M.D. Gottsegen, Chair
The next meeting of this subcommittee will be held on April 19, 2006 in Boston in conjunction with the NAMTA Convention. Chair M. Gottsegen said he would make the necessary arrangements for this meeting but would be unable to attend. He had asked V. Elliott to preside in his absence. Chair Gottsegen reported that he had submitted a paper to promote ASTM to the Tate Museum in London for a seminar on conservation to be held May 15-22, 2006.
The group on Lightfastness of Pigments discussed the revision of D4303, "Lightfastness of Colorants Used in Artists' Materials," that had recently been balloted at the subcommittee level and had received five negatives. There was discussion on the issues involved in the negatives, including the lack of test studies, the effect of relative humidity in tests, and the result that manufacturers may be disinclined to test and conform to standards. Four negatives were ruled persuasive and the fifth was withdrawn. N. Searle and K. Scott agreed to draft revisions involving the issues of illuminant D65 reference conversion, 10-degree observer, and relative humidity. M. Gottsegen reported that he had obtained a grant to evaluate the correlation between the blue wools and D 4303 results.
Specifications group Chair W. Berthel gave a Power Point presentation on the progress of his testing of acrylic gessoes, including the positive effect of size, the unsuitability of hide glue size, and the variation in gesso consistency. He also reported that M. Mecklenburg would test for elongation properties.
Toxicity group Chair W. Stopford reported that Canada's CCCR regulations were being integrated into ACMI's certification program and that he was in the process of harmonizing his risk assessments and labeling for LHAMA requirements in the U.S. with those in Canada. He said that some of Canada's language was superior but some was too restrictive. He reported that he had suggested to Health Canada that they use ASTM PS 124 (auto-combustibility) that this Subcommittee had developed, since they require such labeling but use no test to determine auto-combustibility. He said that he had been testing various oils and that food oils proved to be worse than linseed oil. He also said that consideration should be given to changing the title to encourage wider use. Mr. Stopford also reported that FHSA requires that most products with 10% or more hydrocarbon content must have childproof caps and that writing instruments are not covered. He further reported that, if such aerosols present an aspiration hazard, they are not exempted from labeling as such. He also said that there is no test method to determine the aspiration hazard of aerosols and suggested that this Subcommittee develop such a test method. The group then voted to work on such a test.
Subcommittee Chair M. Gottsegen told the groups on Consumer Evaluation and Colored Pencils that certain footnotes must be removed from ASTM D4941 and D5724 since ASTM standards are not allowed to contain brand names. Mr. D. Pyle reported to the Pastels group that WK739, "Standard Specification for Artists' Pastels," should include replicable tests and that manufacturers should be able to conduct tests on a continuing basis. He also stated that lightfast pigments when incorporated into a pastel are not as lightfast, as there are differences in light fastness between powdered and paste products and multiple-pigment products. He also stated that he believed the standard should be divided into two sections based on the testing mechanisms. After discussion, the group voted to put Draft 6 of the Pastels standard to Subcommittee ballot as written with typographical errors corrected.
D01.61, Paint Application Tools
J.D. Feathers, Chair
D. Kaminsky, Chair of the Paint Brush group, proposed the initiation of work on three new methods for brush testing. The first would develop a method to measure the tendency of a brush to lose filaments, commonly called "shedding." A second method would be developed for judging the accuracy of a brush to "cut-in." This is important especially for brushes used to paint trim. A third method would be to establish a way to rate a brush for its ability to "level" a paint, or its tendency to leave brush marks. The group agreed to work on the first two methods, followed by the third at a later time.
The Paint Rollers group, D. Punches, Chair, reviewed the results of the round-robin conducted on Work Item WK6749, "Proposed Test Method for Fiber Shedding of Paint Roller Covers." The agreement among the cooperators appeared to be good. A Precision and Bias statement will be developed from this data. It was agreed to alter the method to include 5X magnified pictures of typical defects resulting from the roller paint-out to distinguish between fibers and other debris. The group on Knitted Paint Applicator Fabrics, E. Lowder, Chair, reviewed the latest draft of the "Proposed Practice of Physical Characterization of Sliver Knitted Paint Applicator Fabrics." A tensile test will be developed jointly by Rock Valley Textile and Monterey Mills for inclusion in the next draft, which will be registered as a Work Item and distributed for group comment. A round-robin testing half-inch pile fabric will be initiated prior to the June meeting. Test results will be compiled by Monterey Mills.
The group on Fracture Resistance, J. Feathers, Chair, reviewed results of balloting on draft #13 of WK6755, "Proposed Standard Test Method for Testing Fracture of Level Paintbrush Filaments." This method received two comments and one negative during subcommittee balloting. The group voted to find all three persuasive and is making changes that will be reflected in draft #14, which will be reviewed at the June 2006 meeting. Included will be a revised picture to show filaments that passed the testing, a modified filament conditioning statement and a statement on repeatability of the test.
The Brush Stiffness group, M. Lambertson, Chair, reviewed the latest draft of the "Proposed Methods for Evaluating Paint Brush Stiffness." This draft will be revised with changes that include adding two more ASTM methods to the section on reference documents. Round-robin testing will be done on this method after the June 2006 meeting.
G03.02, Natural Environmental Testing
J. Robbins III, Chair
This subcommittee has three active standards: (1) atmospheric and accelerated outdoor weathering, (2) exposure to daylight filtered through glass, and (3) specifications for temperature devices for natural weathering tests. The Black Panels group led by J. Martin, Chair, has completed work on a new document entitled, "Specification for Manufacturing and Use of Black and White Panel Temperature Devices for Natural Weathering Tests." Additional work is continuing concerning the coating for the white panel specified in this standard. The group on Accelerated Outdoor Weathering heard from J. Robbins, Chair, that G90, "Standard Practice for Performing Accelerated Outdoor Weathering of Nonmetallic Materials Using Concentrated Natural Sunlight" (WK1282), had passed G-3 ballot and has been published. The Time of Wetness group discussed determining time of wetness using available temperature and humidity data. Additional discussion will occur at the next meeting.
G03.03, Simulated Controlled Tests
This subcommittee has five active standard practices for operating various accelerated test devices: laboratory light sources, open flame carbon arc, enclosed carbon arc, fluorescent light apparatus for UV exposure, and xenon arc apparatus.
G03.04, Biological Deterioration
J. LaZonby, Chair
This subcommittee has three active methods on resistance to fungi, algal resistance, and microbial susceptibility. The only item currently under consideration is biodeterioration method WK4201, "Mold Growth on Building Products in an Environmental Chamber" that will work off of the D01.28.05 method, which must be completed first. To expedite that process, G03.04 deferred its time back to D01.28.05 so discussion of the new chamber method could be completed.
