This standard BS EN ISO 28721-2:2025 - TC Tracked Changes. Vitreous and porcelain enamels. Glass-lined apparatus for process plants is classified in these ICS categories:
25.220.50 Enamels
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.
