DIN EN ISO 3452-1:2013-09

This document (EN ISO 3452-1:2013) has been prepared by Technical Committee ISO/TC 135 "Non-destructive testing" the secretariat of which is held by AFNOR (France) in collaboration with Technical Committee CEN/TC 138 "Non-destructive testing". The responsible German committee is Working Committee NA 062-08-25 AA "Oberflächenverfahren" ("Surface methods") at the Materials Testing Standards Committee (NMP) at DIN. This part of ISO 3452 specifies a method of penetrant testing used to detect discontinuities, for example cracks, laps, folds, porosity and lack of fusion, which are open to the surface of the material to be tested. It is mainly applied to metallic materials, but can also be performed on other materials, provided that they are inert to the test media and not excessively porous (castings, forgings, welds, ceramics, etcetera). The standard also includes requirements for process and control testing, but is not intended to be used for acceptance criteria and gives neither information relating to the suitability of individual test systems for specific applications nor requirements for test equipment.
