Industrial uses are defined by linking an emulsion grade to an application class, performance targets, and test compliance. Specs typically state intended use such as tack coat, prime coat, surface dressing, slurry seal, cold mix, soil stabilization, or waterproofing, then set limits for binder content, viscosity/flow, particle charge, breaking behavior, storage stability, residue properties, and application temperature. They also specify sampling frequency, acceptance criteria, and the governing test methods. In procurement, the “use” is often defined as a combination of grade plus method statement and QC plan.
