ActiveViterous and porcelain enamels―Determination of resistance to chemical corrosion by boiling acids and their vapours
搪玻璃釉 耐沸腾酸及其蒸气腐蚀性能的测定
Application Summary AI generated
This standard specifies a test method for evaluating the resistance of vitreous and porcelain enamel coatings to corrosion by boiling acids and their vapours. It is applied in the chemical processing, pharmaceutical, and food industries to qualify enamel-lined equipment such as reactors, storage tanks, and piping that must withstand aggressive acidic environments. The test is used for quality control and material selection to ensure long-term durability under harsh chemical exposure.
