This standard specifies product requirements, test methods, inspection rules, marking, Encasement and storage conditions for chlorinated rubber anti-corrosion coatings. Applicable to undercoating, intermediate coating and finish coating with chlorinated rubber as the main film formation material. Coatings usually also contain plasticizers, pigments and solvents. The standard describes the performance test of chlorinated rubber anti-corrosion coatings in detail, including non-volatile-matter content, hiding power, drying time, aging rating, salt spray (fog) resistance, climate resistance, etc., to ensure its anti-corrosion effect and durability under various environment conditions. In addition, the standard also covers the Encasement and marking requirements of coatings to ensure product mass and safety in use.
