GB/T 11418-1989
ActiveDetermination of resistance to heat of vitreous andporcelain enamels
搪瓷耐热性测试方法
Application Summary AI generated
This standard specifies a test method for determining the resistance of vitreous and porcelain enamel coatings to thermal shock and sustained high temperatures. It is applied in the manufacturing and quality control of enameled products, such as cookware, chemical reactors, and sanitary ware, to ensure the coating can withstand operational heat without cracking or peeling. The test is conducted by exposing enameled specimens to specified temperature cycles and evaluating visible damage.
