Which ASTM standards govern testing and classification of bitumen emulsions?

[Timothy]

ASTM frameworks typically separate emulsion classification from test methods used to verify viscosity, residue content, sieve residue, storage stability, and residue properties. In procurement, suppliers cite a grade specification standard and then list the referenced test methods for each parameter on the certificate of analysis. The key practical point is to ensure the grade standard and the test methods match the intended application, because road agencies may require specific subsets or additional performance tests. Always request the latest COA with test method references, not only a statement of compliance.
