Standard Specification for Coal Tar Primer Used in Roofing, Dampproofing, and Waterproofing

ABSTRACT
This specification covers coal tar primer suitable for use with coal tar pitch in roofing, dampproofing, and waterproofing below or above ground level, for application to concrete, masonry, and coal tar surfaces. Different tests shall be conducted in order to determine the following physical properties of coal tar primer: water content, consistency, specific gravity, matter insoluble in benzene, distillation, and coke residue content.
SCOPE
1.1 This specification covers coal tar primer suitable for use with coal tar pitch in roofing, dampproofing, and waterproofing below or above ground level, for application to concrete, masonry, and coal tar surfaces.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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 limitations prior to use.
