ASTM D1187-97(2002)e1
(Specification)Standard Specification for Asphalt-Base Emulsions for Use as Protective Coatings for Metal
Standard Specification for Asphalt-Base Emulsions for Use as Protective Coatings for Metal
ABSTRACT
This specification establishes the manufacture, testing, and performance requirements of two types of asphalt-based emulsions for use in a relatively thick film as a protective coating for metal surfaces. Type I are quick-setting emulsified asphalt suitable for continuous exposure to water within a few days after application and drying. Type II, on the other hand, are emulsified asphalt suitable for continuous exposure to the weather, only after application and drying. Upon being sampled appropriately, the materials shall conform to composition requirements as to density, residue by evaporation, nonvolatile matter soluble in trichloroethylene, and ash and water content. They shall also adhere to performance requirements as to uniformity, consistency, stability, wet flow, firm set, heat test, flexibility, resistance to water, and loss of adhesion.
SCOPE
1.1 This specification covers emulsified asphalt suitable for application in a relatively thick film as a protective coating for metal surfaces.
1.2 The values stated in inch-pound units are to be regarded as the standard.
