Non-destructive testing – Magnetic particle testing - Part 1: General principles
General principles for magnetic particle testing of ferromagnetic materials.
This International Standard specifies general principles for the magnetic particle testing of ferromagnetic materials.
Magnetic particle testing is primarily applicable to the detection of surface-breaking discontinuities, in particular cracks. It can also detect discontinuities just below the surface but its sensitivity diminishes rapidly with depth.
This 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 particular items are defined in product standards.
This standard does not apply to residual magnetization method.
