ActiveVitreous and porcelain enamels—Determination of resistance to chemical corrosion—Part 4: Determination of resistance to chemical corrosion by alkaline liquids using a cylindrical vessel
搪瓷耐化学侵蚀的测定 第4部分：用圆柱形容器进行耐碱溶液侵蚀的测定
Application Summary AI generated
This standard specifies a test method for evaluating the resistance of vitreous and porcelain enamel coatings to corrosion by alkaline liquids, using a cylindrical vessel as the test apparatus. It is applied in the manufacturing and quality control of enameled products, such as chemical reactors, storage tanks, and kitchenware, to ensure their durability in alkaline environments. The test is particularly relevant for industries producing enameled equipment used in chemical processing, food handling, or sanitary ware where exposure to alkaline cleaning agents or process liquids occurs.
