ASTM D173/D173M: Standard Specification for Bitumen-Saturated Cotton Fabrics Used in Roofing and Waterproofing
DOD Adopted ANSI Approved Approved
This specification covers woven cotton fabrics saturated with either asphalt or coal-tar pitch intended to be used with asphalts conforming to Specifications D312 or D449, coal-tar pitches conforming to Specification D450, or appropriate solvent bearing bituminous materials in the construction of roofing and waterproofing systems.
Asphalt-saturated cotton fabric shall be used with asphalt base plying cement; typical ones are mopping asphalts conforming to Specifications D312 or D449 or appropriate solvent bearing asphaltic compounds.
Coal-tar-saturated cotton fabric shall be used with coal-tar based plying cements; a typical one is coal-tar pitch conforming to Specification D450 or appropriate solvent bearing coal-tar compounds.
The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
