DIN Standards Committee Materials Testing

Overview

This document specifies a test method for the determination of the resistance of enamelled articles to attack in closed systems by acid, neutral and alkaline liquids, as well as by actual process mixes. This document applies primarily to the testing of vitreous and porcelain enamels designed for use in chemical processes. Enamelled test specimens are exposed to attack by a liquid corrosive at temperatures above the normal boiling point, under defined autoclave conditions. The loss in mass is determined and used to calculate the rate of loss in mass per unit area.
The International Standard ISO 28706-5:2010 has been prepared by Technical Committee ISO/TC 107 "Metallic and other inorganic coatings" and has been adopted without any modifications as EN ISO 28706-5:2011 by Technical Committee of the European Standardization organization, CEN/TC 262 "Metallic and other inorganic coatings", the secretariat of which is held by BSI (United Kingdom). The responsible German committee is Working Committee NA 062-01-63 AA "Prüfung von Emails und Emaillierungen" ("Testing of vitreous and porcelain enamels") at the Materials Testing Standards Committee (NMP) at DIN.
