This British Standard specifies techniques and procedures for magnetic particle flaw detection of ferromagnetic materials. Magnetic particle flaw detection is primarily used for the detection of surface-breaking flaws, particularly cracks. It can also detect flaws just below the surface, but its sensitivity diminishes rapidly with depth.
