What does BS EN ISO 3452-1:2021 cover?
It specifies a method of penetrant testing used to detect discontinuities, e.g. cracks, laps, folds, porosity and lack of fusion, that are open to the surface of the material to be tested, using white light or UV-A (365 nm) radiation.
It’s mainly applied to metallic materials, but can also be performed on other materials, provided that they are inert to the test media and not excessively porous (castings, forgings, welds, ceramics, etc.)
BS EN ISO 3452-1:2021 also includes requirements for process and control testing.
NOTE 1: Methods for determining and monitoring the essential properties of penetrant testing products to be used are specified in BS EN ISO 3452-2 and BS EN ISO 3452-3.
NOTE 2: The term "discontinuity" is used in this document in the sense that no evaluation concerning acceptability or non-acceptability is included.
Why should you use BS EN ISO 3452-1:2021?
- It supplies a state of the art approach to penetrant testing
- It can improve the efficiency of penetrant testing
- It can help manage the risks of penetrant testing better
- It can produce robust test results
BS EN ISO 3452-1:2021 contributes to UN Sustainable Development Goal 9 on industry, innovation and infrastructure because it helps underpin resilient infrastructure.
