(Specification)Standard Specification for Emulsified Asphalt Used as a Protective Coating for Roofing
Standard Specification for Emulsified Asphalt Used as a Protective Coating for Roofing
ABSTRACT
This specification covers emulsified asphalt suitable for use as a protective coating for built-up roofs and other exposed surfaces with specified inclines. The emulsified asphalts are grouped into three types, as follows: Type I, which contains fillers or fibers including asbestos; Type II, which contains fillers or fibers other than asbestos; and Type III, which do not contain any form of fibrous reinforcement. These types are further subdivided into two classes, as follows: Class 1, which is prepared with mineral colloid emulsifying agents; and Class 2, which is prepared with chemical emulsifying agents. Other than consistency and homogeneity of the final products, they shall also conform to specified physical property requirements such as weight, residue by evaporation, ash content of residue, water content flammability, firm set, flexibility, resistance to water, and behavior during heat and direct flame tests.
SCOPE
1.1 This specification covers emulsified asphalt suitable for use as a protective coating for built-up roofs and other exposed surfaces with inclines of not less than 4 % or 42 mm/m [1/2 in./ft].
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 are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.
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.
