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.

Standard Specification for Lap Cement Used with Asphalt Roll Roofing, Non-Fibered, and Fibered

ABSTRACT
This specification covers the physical requirements and testing of three types of lap cement for use with asphalt roll roofing. Type I is a brushing consistency lap cement intended for use in the exposed-nailing method of roll roofing application, and contains no mineral or other stabilizers. This type is further divided into two grades, as follows: Grade 1, which is made with an air-blown asphalt; and Grade 2, which is made with a vacuum-reduced or steam-refined asphalt. Both Types II and III, on the other hand, are heavy brushing or light troweling consistency lap cement intended for use in the concealed-nailing method of roll roofing application, only that Type II cement contains a quantity of short-fibered asbestos, while Type III cement contains a quantity of mineral or other stabilizers, or both, but contains no asbestos. The lap cements shall be sampled for testing, and shall adhere to specified values of the following properties: water content; distillation (total distillate at given temperatures); softening point of residue; solubility in trichloroethylene; and strength at indicated age.
SCOPE
1.1 This specification covers lap cement consisting of asphalt dissolved in a volatile petroleum solvent with or without mineral or other stabilizers, or both, for use with roll roofing. The fibered version of these cements excludes the use of asbestos fibers.  
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 nonconformance with the standard.  
1.3 The following precautionary caveat applies only to the test method portion, Section 6, 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, 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.
