June 2005 subcommittee reports of ASTM Committee G03.

G03.02, Natural Environmental Testing

J. Robbins III, Chair

The group on Black Panels, 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 specified for the white panel specified in this standard. The Outdoor Tests group heard that G 7, "Standard Practice for Atmospheric Environmental Exposure Testing of Nonmetallic Materials" and G 24, "Standard Practice for Conducting Exposures to Daylight Filtered through Glass" have both been published.

The Accelerated Outdoor Weathering group reviewed a subcommittee ballot of G 90, "Standard Practice for Performing Accelerated Outdoor Weathering of Nonmetallic Materials Using Concentrated Natural Sunlight." The G03.02 ballot received one negative vote which was withdrawn. This standard will be sent for a G-3 ballot prior to the next meeting. The group on Time of Wetness discussed determining time of wetness using available temperature and humidity data. Additional discussion will occur at the next meeting.

G03.04, Biological Deterioration 

J.G. LaZonby, Chair

W. Ketola, Chair of G03 informed the group that C. Wittman had stepped down as the G03.04 subcommittee chair. J. LaZonby has volunteered to step into the role. Since the only item under consideration in this subcommittee is the Biodeterioration method that will work off of the D01.28.05 method, G03.04 deferred its time back to D01.28.05 so discussion of the new chamber method could continue.
