Standard Specification for Asphalt Glass Felt Used in Roofing and Waterproofing (Withdrawn 2013)
SCOPE
1.1 This specification covers glass felts impregnated with asphalt that may be used with asphalts conforming to the requirements of Specification D 312 in the construction of built-up roofs, and with asphalts conforming to the requirements of Specification D 449 in the membrane system of waterproofing.
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
WITHDRAWN RATIONALE
This specification covers glass felts impregnated to varying degrees with asphalt intended to be used with asphalts conforming to the requirements of Specification in the construction of built-up roofs, and with asphalts conforming to the requirements of Specification in the construction of waterproofing systems.
Formerly under the jurisdiction of Committee D08 on Roofing and Waterproofing, this specification was withdrawn in January 2013 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by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.
