ASTM D6753-02(2008)

Standard Specification for Coal Tar Adhesive

ABSTRACT
This specification covers coal tar adhesive with or without polymer modification suitable for brush, spray, squeegee and trowel application to coal tar built up and coal tar modified bitumen membrane roofings and flashings. The adhesive shall be classified as: Type I and Type II. Coal tar adhesive shall consist of a processed coal tar base, volatile solvents, mineral stabilizers, with or without polymer modifiers excluding asbestos, mixed to a smooth consistency. The following test methods shall be performed to conform with the requirements of the material: nonvolatile matter; water; ash; lap shear strength; and peel strength.
SCOPE
1.1 This specification covers coal tar adhesive with or without polymer modification suitable for brush, spray, squeegee and trowel application to coal tar built up and coal tar modified bitumen membrane roofings and flashings.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information purposes only.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use.
