Overview

This International Standard specifies techniques for detection of surface imperfections in welds in ferromagnetic materials, including the heat affected zones, by means of magnetic particle testing. The techniques are suitable for most welding processes and joint configurations. Variations in the basic techniques that will provide a higher or lower test sensitivity are described in Annex A. This International Standard does not specify acceptance levels of the indications. Further information on acceptance levels for indications may be found in EN 23278 or in product or application standards. This document (EN ISO 17638:2015) has been prepared by Technical Committee ISO/TC 44 "Welding and allied processes" in collaboration with Technical Committee CEN/TC 121 "Welding", the secretariat of which is held by AFNOR. The responsible German standardization committee is Working Committee NA 062-08-24 AA "Elektrische und magnetische Prüfverfahren" ("Electrical and magnetic test methods") at DIN Standards Committee Materials Testing (NMP).
