Scope

This document specifies the product classification, requirements, test methods, inspection rules, and packaging, marking, and storage for emulsions used in architectural coatings.
This document is applicable to emulsions that play a film-forming and bonding role in interior and exterior wall coatings, which are formed by emulsion polymerization of monomers such as styrene, acrylic acid and its esters, methacrylic acid and its esters, vinyl acetate, and other olefins, and are dispersed in water as a dispersion medium.
