This 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 European Standard is not intended to be used for acceptance criteria and gives no information relating to the suitability of individual test systems for specific applications or requirements for test equipment. Methods for determining and monitoring the essential properties of penetrant testing products to be used are specified in BS EN 571-2 and BS EN 571-3.
