DIN Standards Committee Technology of Materials

Overview

This document (EN ISO 9934-1:2016) has been prepared by Technical Committee CEN/TC 138 "Non-destructive testing", the secretariat of which is held by AFNOR (France), in collaboration with Technical Committee ISO/TC 135 "Non-destructive testing". The responsible German committee is Working Committee NA 062-08-23 AA "Elektrische und magnetische Prüfverfahren" ("Electrical and magnetic test methods") at DIN Standards Committee Materials Testing (NMP). This part of ISO 9934 specifies general principles for the magnetic particle testing of ferromagnetic materials. Magnetic particle testing is primarily applicable to the detection of surface-breaking discontinuities, particularly cracks. It can also detect discontinuities just below the surface but its sensitivity diminishes rapidly with depth. This part of ISO 9934 specifies the surface preparation of the part to be tested, magnetization techniques, requirements and application of the detection media, and the recording and interpretation of results. Acceptance criteria are not defined. Additional requirements for the magnetic particle testing of particular items are defined in product standards (see the relevant International Standards or European standards). This part of ISO 9934 does not apply to the residual magnetization method.
