ASTM D173 / D173M - 03(2011)e1 Standard Specification for Bitumen-Saturated Cotton Fabrics Used in Roofing and Waterproofing


资源简介
1. Scope ^SCOPE: 1.1 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. 1.1.1 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. 1.1.2 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. 1.2 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. ^REFERENCE: ASTM Standards: D146 Test Methods for Sampling and Testing Bitumen-Saturated Felts and Woven Fabrics for Roofing and Waterproofing D312 Specification for Asphalt Used in Roofing D449 Specification for Asphalt Used in Dampproofing and Waterproofing D450 Specification for Coal-Tar Pitch Used in Roofing, Dampproofing, and Waterproofing D1079 Terminology Relating to Roofing and Waterproofing D3775 Test Method for Warp (End) and Filling (Pick) Count of Woven Fabrics
