|ICS Code (Non-destructive testing):||19.100|
This standard deñnes a method of penetrant testing used to detect discontinuities, e.g. cracks, laps, folds, porosity and iack of fusion, which are open to the surface of the material to be tested It is mainly applied to metallic materiais, 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 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 nor requirements for test equipment, The term 'discontinuity' is used here in the sense that no evaluation concerning acceptability or non-acceptability is included.
Methods for determjning and monitoring the essentiai properties of penetrant testing products to be used are specified in EN 571-2 and EN 5713.
