适用范围：The document specifies a method of determining, by successive thermal shock tests, the behaviour of vitreous and porcelain enamelled cooking utensils and similar articles under sudden changes of temperature (resistance to thermal shock). Using this test method specified, a series of single thermal shock tests is conducted with a temperature increase of 20 ?between each thermal shock obtained by heating the test specimen from the outside and then chilling it inside with water at 20 ? For the first test, the thermal shock temperature amounts to 200 ? The test ends when the first visible damage occurs.
