This standard specifies the test method for the performance of the Glass-lined layer to withstand the sudden change of temperature difference, which is suitable for the determination of the Glass-lined plate specimen. By heating the sample to a specific temperature, quickly spray cold water to observe whether the Glass-lined layer is damaged, such as bursting porcelain, cracking, etc. During the test, the temperature difference is gradually increased until the Glass-lined layer is damaged to determine the temperature difference and sudden change temperature. This standard provides a scientific basis for evaluating the tolerance performance of the Glass-lined layer under the condition of drastic temperature change.
