Non-destructive testing. Penetrant testing - General principles Ingestion-build-54484 provided that they are inertThis part of BS EN 571 defines a method of penetrant testing used to detect discontinuities, e. g. cracks, laps, folds, porosity and lack of fusion, which are open to the surface of the material to be tested. It is mainly applicable to metallic materials, but can also be performed on other materials, provided that they are inert to the test media and they are not excessively porous, examples of which are castings, forgings, welds, ceramics, etc. This
