Non-destructive testing - Magnetic particle testing - Part 1: General principles (ISO 9934-1:2015); German version EN ISO 9934-1:2015
This document 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.The standard 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 particularitems are defined in product standards (see the relevant EN Standard).
