AbolishedVitreous and porcelain enamels—Determination of resistance to chemical corrosion—Part 2: Determination of resistance to chemical corrosion by boiling acids, boiling neutral liquids and/or their vapours
搪瓷耐化学侵蚀的测定 第2部分：耐沸腾酸、沸腾中性液体及其蒸气化学侵蚀的测定
Application Summary AI generated
This standard specifies a test method for evaluating the resistance of vitreous and porcelain enamel coatings to corrosion from boiling acids, boiling neutral liquids, and their vapours. It is applied in the manufacturing and quality control of enameled products, such as chemical processing equipment, cookware, and sanitary ware, to ensure durability under harsh chemical exposure. The test is critical for industries where enameled surfaces must withstand aggressive chemical environments, including laboratories and industrial processing plants.
