scope:

1.1 This specification covers woven burlap fabrics, saturated with either asphalt or refined coal-tar, as specified by the purchaser, for use in the membrane system of roofing or waterproofing or as specified by the manufacturer.

1.1.1 Asphalt-saturated burlap fabric shall be used with asphalt base plying cement; typical ones are mopping asphalts conforming to Specifications D312/D312M, D449/D449M, or appropriate solvent-bearing bituminous materials.

1.1.2 Coal-tar-saturated burlap fabric shall be used with coal-tar base plying cements; typical ones are coal-tar pitches conforming to Specification D450/D450M, or appropriate solvent-bearing bituminous materials.

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 nonconformance 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.
