What is BS EN 60404-5 – Methods of measurement of magnetic properties about?
BS EN 60404-5 is a European standard on magnetic materials is the fifth part of multi-series that defines the method of measurement of the magnetic flux density, magnetic polarization, and the magnetic field strength and also to determine the demagnetization curve and recoil line of permanent magnet materials.
The performance of a magnetic system is not only dependent on the properties of the permanent magnet material but also on the dimensions of the system, the air gap, and other elements of the magnetic circuit.
Who is BS EN 60404-5 - Methods of measurement of magnetic properties for?
BS EN 60404-5 on Methods of measurement of magnetic properties is relevant to:
- Magnetic material manufacturers
- Transition metal manufacturers
- Manufacturers of industrial applications such as transformers, inductors, etc
- Metallurgists
- Product engineers
- Electrical engineers
- Quality testing team
Why should you use BS EN 60404-5 - Methods of measurement of magnetic properties?
A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field.
BS EN 60404-5 provides you specifications on electromagnet and conditions, determination of the magnetic flux density, measurement of the magnetic field strength, determination of the principal characteristics with test reports that helps you in classification of unprotected electric cables.
As a result, BS EN 60404-5- enables you to assess the quality of the materials, identify the right magnetic materials for your specific manufacturing methods and engineering needs.
What’s changed since the last update?
BS EN 60404-5:2015 replaces the second edition published in 1993 and amendment
1:2007. This edition includes the following significant technical changes with respect to the previous edition:
- Adaption of the measurement methods and test conditions to newly introduced magnetically hard materials with coercivity values HcJ higher than 2 MA/m
- Update of the temperature conditions to allow the measurement of new materials with high-temperature coefficients
