ASTM D1227/D1227M-13 (R2019)e1 PDF Download

The ASTM D1227/D1227M-13 (R2019)e1 standard defines the characteristics and requirements for emulsified asphalt coatings used on built-up roofs and other exposed surfaces with specified inclines.

The standard categorizes the emulsified asphalts into three types: Type I, which contains fillers or fibers including asbestos; Type II, which contains fillers or fibers other than asbestos; and Type III, which does not contain any form of fibrous reinforcement. Each type is further divided into two classes: Class 1, which is prepared with mineral colloid emulsifying agents; and Class 2, which is prepared with chemical emulsifying agents.

In addition to consistency and homogeneity, the emulsified asphalts must meet specific 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.
