The ASTM D7072-04 (2019) standard provides a method for evaluating the vulnerability of emulsion coatings to efflorescences on highly water-soluble salt substrates. This standard helps analyze the durability of emulsion coatings by testing the degree of efflorescences and alkali burnout of coatings when exposed to moisture. Applicable to paintings of concrete blocks, masonry, and similar materials, it provides an objective assessment of emulsion coating performance, especially in environments with severe efflorescences.
