What is BS EN 1369 – Magnetic particle testing about?
BS EN 1369 is a European standard that discusses the founding of magnetic particle testing. Magnetic particle testing uses small magnetic particles and magnetic fields to find flaws in various products such as forgings, castings and weldments.
BS EN 1369 specifies a magnetic particle testing method for ferromagnetic iron and steel castings.
Who is BS EN 1369 – Magnetic particle testing for?
BS EN 1369 on magnetic particle testing applies to:
- Inspection of magnetic particle
- Laboratory testing
- Manufacturing of Magnetic particle imaging machines
Why should you use BS EN 1369 – Magnetic particle testing?
Magnetic particle testing as well as any other non-destructive examination method is a part of a general or specific assessment of the quality of casting to be agreed upon between the manufacturer and the purchaser at the time of acceptance of the order. BS EN 1369 provides acceptance criteria through severity levels defined by the nature, the area and the dimensions of the discontinuities present.
BS EN 1369 provides you with a guide in operating mode for the method of testing, in which the testing is carried out by magnetizing sequentially in two directions perpendicular to each other. BS EN 1369 ensures that each discontinuity runs against the flux in at least one direction. When the direction of stress is known, the testing is been performed in one direction only, to take into account, the most detrimental discontinuity.
BS EN 1369 gives you the conditions for magnetic particle testing in which the methods detailed in BS EN 1369 apply to the agreed surfaces of the castings and the percentage number of castings is checked. The areas of the castings and the percentage of the castings are inspected is indicated in the enquiry. This helps you to specify at least:
- The method to be used (type of detection media)
- Whether the casting is to be demagnetized after testing has been performed (viz. maximum residual field strength values).
