Application Summary AI generated

This standard specifies a test method for evaluating the resistance of vitreous and porcelain enamel coatings to chemical corrosion when exposed to liquids in a sealed, closed system. It is applied in the manufacturing and quality control of enameled products, such as chemical reactors, storage tanks, and piping used in the chemical processing industry. The test simulates conditions where the enamel surface is in continuous contact with corrosive media under pressure or at elevated temperatures, ensuring durability in demanding industrial environments.
