What is BS EN 1371-2 - Liquid penetrant testing about?
BS EN 1371-2 is the second part of a series of European standards on liquid penetrant testing that discusses the best procedures and specifications required to detect any surface-connected discontinuities on castings.
BS EN 1371-2 specifies a liquid penetrant testing method for castings produced by investment casting for general purposes.
BS EN 1371-2 applies to all cast metals, except copper-tin and/or copper-tin-lead alloy castings, where copper is the major constituent.
NOTE: Investment casting is sometimes referred to as lost-wax casting.
Who is BS EN 1371-2 - Liquid penetrant testing for?
BS EN 1371-2 on liquid penetrant testing method for castings produced is relevant to:
- Casting foundry
- Mechanical engineer
Why should you use BS EN 1371-2 - Liquid penetrant testing?
Liquid penetrant inspection is used to detect any surface-connected discontinuities such as cracks from fatigue, quenching, and grinding, as well as fractures, porosity, incomplete fusion, and flaws in joints.
BS EN 1371-2 provides guidance on conditions for liquid penetrant testing, method of testing, operating mode, qualification of the operators, surface preparation, acceptance criteria.
As a user of BS EN 1371-2, you can ensure the quality of investment castings and can detect any surface-connected discontinuities such as cracks from fatigue, quenching, and grinding, as well as fractures, porosity, incomplete fusion, and flaws in joints by using the liquid penetrant testing. BS EN 1371-2 could give you the best guidance in performing liquid penetrant testing without any difficulties, this helps to improve the quality of products thus, you would gain customer trust and confidence in the product.
