Scope

This Part of GB/T 15822 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 Part 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 Part does not apply to the residual magnetization method.

Summary	This standard specifies: General ferromagnetic magnetic particle testing. Magnetic particle testing is mainly used to detect surface openings not continuous, also detected near the surface not continuous, but its sensitivity decreases rapidly with depth. This standard specifies: was seized artifacts surface preparation, magnetic technology, testing media Requirements and applied, and the results recording and interpretation. Not specified acceptance criteria. For special items Day Magnetic particle testing, additional requirements specified by the product standard.
