Abstract
This specification covers two types of asbestos-containing asphalt roof coatings consisting of an asphalt base, volatile petroleum solvents, and mineral stabilizers including asbestos fiber, mixed to a smooth, uniform consistency suitable for application by squeegee, three-knot brush, paint brush, roller, or by spraying. Type I is made from asphalts characterized as self-healing, adhesive, and ductile, while Type II is made from asphalts characterized by high softening point and relatively low ductility. The coatings shall comply with specified composition limits of water, nonvolatile matter, asbestos and other mineral stabilizers, asphalt, and mineral matter based on original mass of insoluble residue. They shall also adhere to physical requirements as to uniformity, consistency, and pliability and behavior at given temperatures.
Scope
1.1 This specification covers asbestos-containing asphalt roof coatings of brushing or spraying consistency.
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 and health practices and determine the applicability of regulatory limitations prior to use.
