Overview

This document establishes a system for the cataloguing of defects in enamellings for chemical service and vessels. In addition, it describes some types of areas in which defects have been treated and which can easily be confounded with enamelling defects. It serves for a consistent language use concerning the designation and characterization of enamelling defects. This standard is limited to detectable defects and does not purport to fully take into consideration all occurring types of defects. It does not evaluate enamelling defects; the classification carried out is based on experience and corresponds, as far as possible, to ISO 28721-1. Regarding the acceptance of glass lined equipment for use in process engineering, ISO 28721-1 applies. This standard has been prepared by Technical Committee CEN/TC 262 "Metallic and other inorganic coatings", the secretariat of which is held by BSI, in collaboration with Technical Committee ISO/TC 107 "Metallic and other inorganic coatings". The responsible German standardization committee is Working Committee NA 062-01-63 AA "Prüfungen von Emails und Emaillierungen" ("Testing of vitreous and porcelain enamels") at DIN Standards Committee Materials Testing (NMP).
