This standard defines a method of penetrant testingused to detect discontinuities, e.g. cracks, laps, folds,porosity and lack of fusion, which are open toThesurface of the material to be tested. It is main>,y applito metallic materials, but can also be performed onother materials, provided thatThey are inert toThe tomedia andThey are not excessively porous, examplesof which are s}}nQS. formn}s, welds, ceramics, etc.This standard defines a method of penetrant testingused to detect discontinuities, e.g. cracks, laps, folds,porosity and lack of fusion, which are open toThesurface of the material to be tested.
