04.04 Roofing and Waterproofing / Кровельные покрытия и Гидроизоляционные материалы

This specification covers the testing and physical requirements of two types of coal-tar pitch suitable for use in the construction of built-up roofing, dampproofing, and membrane waterproofing systems. The coal-tar pitch shall be prepared from selected crudes using suitable refining processes, and shall be homogeneous and free of water. Materials shall be sampled, tested, and conform to properties such as water content, specific gravity, ring-and-ball softening point, Cleveland open cup flash point, solubility in carbon disulfide, ash content, and distillation (total distillates and residue).

1.1 This specificationcovers two types of coal-tar pitch suitable for use in theconstruction of built-up roofing, dampproofing, and membranewaterproofing systems.

1.2 The values stated ineither SI units or inch-pound units are to be regarded separatelyas standard. The values stated in each system may not be exactequivalents; therefore, each system shall be used independently ofthe other. Combining values from the two systems may result innon-conformance with the standard.
