What is ISO 3452‑1 - Penetrant testing principles about?
ISO 3452‑1 specifies 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 using white light or UV-A (365 nm) radiation.
ISO 3452‑1 also includes requirements for process and control testing but is not intended to be used for acceptance criteria. It gives neither information relating to the suitability of individual test systems for specific applications nor requirements for test equipment.
Note 1: ISO 3452‑1 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.)
Note 2: Methods for determining and monitoring the essential properties of penetrant testing products to be used are specified in ISO 3452-2 and ISO 3452-3.
Note 3: The term "discontinuity" is used in this document in the sense that no evaluation concerning acceptability or non-acceptability is included.
Note 4: CEN/TR 16638 addresses penetrant testing using actinic blue light
Who is ISO 3452‑1 - Penetrant testing principles for?
BS EN ISO 3452‑1 on penetrant testing is useful for:
- Welders
- Welding inspectors
- Regulatory bodies
- Preparation and precleaning personals
- Metals, plastics or ceramics manufacturers
Why should you use ISO 3452‑1 - Penetrant testing principles?
Penetrant testing reveals the defects that are open to the surface.
ISO 3452‑1 supplies a state-of-the-art approach to penetrant testing. ISO 3452‑1 can improve the efficiency of penetrant testing. ISO 3452‑1 can help manage the risks of penetrant testing better. ISO 3452‑1 can produce robust test results.
BS EN ISO 3452-1 contributes to UN Sustainable Development Goal 9 on the industry, innovation, and infrastructure because it helps underpin resilient infrastructure.
What’s changed since the last update?
ISO 3452‑1:2021 supersedes BS EN ISO 3452‑1:2013, which is withdrawn.
The main changes compared to the previous edition are as follows:
- clarification of understanding of product family
- addition of the new procedure “no developer”
- technical revision according to the state of the art
