Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

ICS Number Code The inspection medium shall consist of finely divided ferromagnetic particles, whose size, shape and magnetic properties, both individually and collectively, shall be taken into account. Alternating current is not permitted because its capability to detect subsurface discontinuities is very limited and therefore unsuitable.

While the material is properly magnetized, the magnetic particles may be applied by either the dry method, wet method, or fluorescent method. This standard does not contain acceptance standards or recommended quality levels.
