What is BS EN 10251- Geometrical characteristics of electrical steel sheet and strip about?
BS EN 10251 is a European Standard on magnetic materials. The main aim of the series is to provide manufacturers with best industry guidance and practices to assess the performance of magnetic materials.
BS EN 10251 is intended to define the test methods used for the determination of the following geometrical characteristics of electrical steel sheet and strip:
- Flatness
- Residual curvature
- Edge camber
- Deviation from the shearing line due to internal stresses
- Burr height of cut edges
BS EN 10251 applies to electrical steel sheets and strips intended for the construction of magnetic circuits and corresponds to Clauses B2, C21, and C22 of IEC 60404-1:2000.
Who is BS EN 10251- Geometrical characteristics of electrical steel sheet and strip for?
BS EN 10251 on magnetic materials is relevant to:
- Magnetic material manufacturers
- Flat-steel products and semi-product manufacturers
- Manufacturers of industrial applications such as transformers, inductors etc
- Metallurgists
- Product design engineers
- Electrical engineers
- Quality testing personnel
Why should you use BS EN 10251- Geometrical characteristics of electrical steel sheet and strip?
BS EN 10251 provides best industry guidance on test methods to determine the flatness, residual curvature, edge camber, and burr height. Assessing these characteristics is critical to the performance of electrical steel sheet and strip, and determine the operational efficiency of the end-application.
Thus, BS EN 10251 can determine the performance of electrical steel sheet and strip, such that it plays a positive role in the functioning of the end application. As a result, if you are a manufacturer, you can determine whether or not your products are fit for purpose, and ultimately minimize risk of product failures.
