This specification covers woven burlap fabrics, saturated with either asphalt or refined coal-tar for use in the membrane system of roofing or waterproofing. Asphalt-saturated burlap fabric shall be used with asphalt base plying cement; typical ones are mopping asphalts or appropriate solvent-bearing bituminous materials. Coal-tar-saturated burlap fabric shall be used with coal-tar base plying cements; typical ones are coal-tar pitches or appropriate solvent-bearing bituminous materials. The fabric to be saturated shall be composed of 100 % jute fiber except for two cotton threads in each selvage. In the process of manufacture, the dry burlap fabric shall be saturated with bitumen. Different tests shall be conducted in order to determine the following properties of woven burlap fabrics: gross mass per roll, mass of wrapping material and mandrel, width of roll, width of selvage, average net mass per unit area, detached comminuted surfacing, moisture, average breaking strength, pliability, mass of desaturated fabric, mass of saturant, thread count, and ash content.

This abstract is a brief summary of the referenced standard.

1. 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, D449, 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, 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 non-conformance with the standard.
