ASTM D6577-2019 is a guide to testing standards for industrial protective coatings designed to assist in the selection of appropriate test methods to evaluate the expected performance of coatings in a given environment. The guide highlights the importance of surface preparation and notes that test results cannot predict the service life of coatings alone, but instead need to be compared to control coatings with known performance. The guide applies to a variety of Coating application methods, including brushing, rolling, and lame plating, and recommends the selection of test criteria based on specific requirements and protocols.
