DIN EN ISO 2746:2016-02

This document describes two test methods of high voltage testing: - Test A is used to detect and locate defects in vitreous and porcelain enamels; - Test B is used to detect and locate defects and weak spots in vitreous and porcelain enamels. The tests are performed using DC or pulsed DC high voltage. The tests are applicable to dry surfaces of enamel coatings. In the case of moist surfaces, care should be taken to ensure that the locating of any defects is correctly performed. This document (EN ISO 2746:2015) has been prepared by Technical Committee CEN/TC 262 "Metallic and other inorganic coatings", the secretariat of which is held by BSI (United Kingdom), 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).
