ActiveTest method of vitreous and porcelain enamels―Part 9: Determination of adhesion tensile strength
搪玻璃层试验方法 第9部分：抗拉强度的测定
Application Summary AI generated
This standard specifies a test method for determining the tensile adhesion strength of vitreous and porcelain enamel coatings applied to metal substrates. It is used in the manufacturing and quality control of chemical processing equipment, such as glass-lined steel reactors and storage tanks, where the enamel layer must withstand mechanical stress without delamination. The method is applied during product development, production inspection, and failure analysis to ensure coating integrity under tensile loading conditions.
