Standard Specification for Bitumen-Saturated Woven Burlap Fabrics Used in Roofing and Waterproofing

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 D 312 or D 449.  
1.1.2 Coal-tar-saturated burlap fabric shall be used with coal-tar base plying cements; a typical one is coal-tar pitch conforming to Specification D 450.
1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
