This practice describes test conditions and procedures for enclosed carbon-arc exposures conducted according to Practices and for bituminous roofing and waterproofing materials that have a minimum softening point of approximately 95°C (200°F) as determined by Test Method . (See also Terminology .)
Formerly under the jurisdiction of Committee D08 on Roofing and Waterproofing, this practice was withdrawn in January 2013 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
1.1 This practice describes test conditions and procedures for enclosed carbon-arc exposures conducted according to Practices G 151 and G 153 for bituminous roofing and waterproofing materials that have a minimum softening point of approximately 95°C (200°F) as determined by Test Method D 36. (See also Terminology G 113.)
