This specification covers three types of aluminum-pigmented asphalt roof coatings suitable for application to roofing or masonry surfaces by brush or spray. Type I is nonfibered, Type II is fibered with asbestos, and Type III is fibered other than asbestos. The coatings shall adhere to chemical requirements such as composition limits for water, nonvolatile matter, metallic aluminum, and insolubility in CS2. They shall also meet physical requirements as to uniformity, consistency, and luminous reflectance.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This specification covers asphalt-based, aluminum-pigmented roof coatings suitable for application to roofing or masonry surfaces by brush or spray.
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 The following precautionary caveat pertains only to the test method portion, Section 8, of this specification: 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.
