标准摘要
[中文适用范围]： 本文件规定了化学搪瓷抗化学攻击和热冲击的要求，以及订购目的的设计标志。适用于涂敷在低碳合金钢板上的玻璃衬里设备、管道和其他部件所用的搪瓷。 [外文原描述]： This document specifies requirements for the resistance of chemical enamels to chemical attack and thermal shock, as well as their designation, for ordering purposes. It is applicable to enamels used in glass-lined apparatus, piping and other components, primarily used in process equipment in chemical plants, which are applied on to low-alloy carbon steels substrates. NOTE The main criteria for assessing enamel quality are its resistance to chemical attack and thermal shock, and the structure of the cover coat enamel.
