JSA JIS Z 2320-1

Abstract

This 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, particularly 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 particular items are defined in product standards (see relevant standards). NOTE: The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows. ISO 9934-1: 2015 Non-destructive testing-Magnetic particle testingPart 1: General principles (MOD) In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/ lEe Guide 21-1.
