Non destructive testing - Penetrant testing - Part 1: General principles

Publication date:   Jan 1, 2000

Scope

This standard 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 maily applied to metallic materials, but can also be performed on other materials, provided that 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 equipement. The term "discontinuity" is used here in the sense that no evaluation concerning acceptability or non-acceptability is included. Metods for determining and monitoring the essential properties of penetrant testing products to be used are specified in EN 571-2 and EN 571-3.
