(Specification)Standard Specification for Bitumen-Saturated Cotton Fabrics Used in Roofing and Waterproofing
Standard Specification for Bitumen-Saturated Cotton Fabrics Used in Roofing and Waterproofing
ABSTRACT
This specification covers woven cotton fabrics saturated with either asphalt or coal-tar intended for use with asphalt based plying cement (such as mopping asphalts or appropriate solvent bearing asphaltic compounds), coal-tar based plying cement (such as coal-tar pitch or other appropriate solvent bearing coal-tar compounds), or appropriate solvent bearing bituminous materials in the construction of roofing and waterproofing systems. The dry cotton fabric shall be thoroughly and uniformly saturated with bitumen by passing the fabric through the saturant or by spraying with saturant, calendering in the presence of heat, and then cooling before winding on a core. Products shall be sampled, tested, and adhere accordingly to specified physical (breaking load in both the warp and fill directions, and pliability), and dimensional (mass, width, thread count, moisture, and ash content) property requirements. The finished product shall not crack nor be so sticky as to cause tearing or other damage upon being unrolled at a given temperature.
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/D312M or D449/D449M, coal-tar pitches conforming to Specification D450/D450M, 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/D312M or D449/D449M 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/D450M 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.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
