(Specification)Standard Specification for Coal Tar Roof Cement, Asbestos Free
Standard Specification for Coal Tar Roof Cement, Asbestos Free
ABSTRACT
This specification covers coal tar roof cement suitable for trowel application in coal tar roofing and flashing systems. The chemical composition of coal tar roof cement shall conform to the requirements prescribed. The water, non-volatile matter, insoluble matter, behaviour at 60 deg. C, adhesion to wet surfaces, and flash point shall be tested to meet the requirements prescribed.
SCOPE
1.1 This specification covers coal tar roof cement suitable for trowel application in coal tar roofing and flashing systems.
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.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
