CEN/TC 138/WG 5 - Magnetic particle testing

ISO 9934-1:2016 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.
ISO 9934-1:2016 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).
ISO 9934-1:2016 does not apply to the residual magnetization method.

ISO 12707:2016 defines general terms specifically associated with magnetic particle testing.

ISO 9934-2:2015 specifies the significant properties of magnetic particle testing products (including magnetic ink, powder, carrier liquid, contrast aid paints) and the methods for checking their properties.

ISO 9934-3:2015 describes three types of equipment for magnetic particle testing:
-      portable or transportable equipment;
-      fixed installations;
-      specialized testing systems for testing components on a continuous basis, comprising a series of processing stations placed in sequence to form a process line.
Equipment for magnetizing, demagnetizing, illumination, measurement, and monitoring are also described.
This part of ISO 9934 specifies the properties to be provided by the equipment supplier, minimum requirements for application and the method of measuring certain parameters. Where appropriate, measuring and calibration requirements and in-service checks are also specified.

This part of European Standard applies to three types of equipment for magnetic particle testing: - transportable equipment; - fixed installations; - fixed installations for testing components on a continuous basis, comprising a series of processing stations placed in sequence to form a process line. Equipment for magnetising, demagnetising, illumination, metering and monitoring are also described.
