The ISO 8504-2:2019 "Preparative cleaning of steel linings before use in coatings and related products - Part 2: Sand blasting cleaning" standard specifies the method of sand blasting cleaning of steel surfaces to ensure good adhesion and protective performance of coatings. The standard details sand blasting cleaning equipment and operating procedures, and provides information on the application and effectiveness of various sand blasting methods. Sand blasting cleaning is a mechanical surface preparation technique that efficiently removes rust, contaminants and old coatings from steel surfaces and is suitable for a variety of steel surface conditions. This method can produce different surface profiles and cleaning effects, and improve the durability and adhesion of the coating. This standard applies to hot-rolled steel and cold-rolled steel of sufficient thickness.
