The GB/T 11419-2008 standard specifies the method for determining the temperature resistance of enamel cookware. It specifies the equipment required for the test, such as heating and chilling down devices, and details the operation process, including placing enamel cookware in a specific temperature difference environment for cycle testing. Temperature resistance is related to the ability of enamel cookware to cope with sudden changes in temperature during daily use, which affects its service life. This standard provides a basis for manufacturers to test the mass of products and consumers to judge the durability of products. It ensures that enamel cookware can withstand frequent temperature changes, reduce the risk of damage such as cracking, and ensure the safety of use.
