DIN Standards Committee Materials Testing

Overview

This standard describes a test method for the determination of the resistance of flat surfaces of vitreous and porcelain enamels to boiling acids, boiling neutral liquids and/or their vapours. This specified method allows the determination of the resistance of vitreous and porcelain enamels to the liquid and vapour phases of the corrosive medium simultaneously. A set of similarly enamelled test specimens is placed in the liquid zone and/or in the vapour zone of the test apparatus, as required, and exposed to attack by a boiling acid or boiling neutral liquid, or its vapour, under specified conditions. The same design of test apparatus and the same test principle is employed for the different liquids. The loss in mass is determined and used to calculate the rate of loss in mass per unit area and, if necessary, the corrosion rate. The International Standard ISO 28706-2:2008 has been prepared by Technical Committee ISO/TC 107 "Metallic and other inorganic coatings" and has been adopted without any modifications as EN ISO 28706-2:2011 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 NMP.
