What is BS EN 60404-15 - Magnetic permeability of feebly magnetic materials about?
BS EN IEC 60404 is a multi-part series of international standard that discusses 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 60404-15 is the 15th part of the series that specifies a solenoid method, a magnetic moment method, a magnetic balance method, and a permeability meter method for the determination of the relative magnetic permeability of feebly magnetic materials.
The magnetic balance and permeability meter methods are both comparison methods calibrated using reference materials to determine the value of the relative magnetic permeability of the test specimen.
NOTE:1 The relative magnetic permeability range given for the magnetic balance method covers the inserts provided with a typical instrument. These can only be assessed at values for which calibrated reference materials exist.
NOTE:2 For a relative magnetic permeability larger than 2, reference material cannot be calibrated using this written standard. A note of this is given in the test report explaining that the values measured using the magnetic balance are for indication only.
Who is BS EN 60404-15 - Magnetic permeability of feebly magnetic materials for?
BS EN 60404-15 on magnetic materials is relevant to:
- Magnetic material manufacturers
- Metal manufacturers
- Manufacturers of industrial applications such as transformers, inductors etc
- Metallurgists
- Product engineers
- Electrical engineers
- Quality testing personnel
Why should you use BS EN 60404-15 - Magnetic permeability of feebly magnetic materials?
The determination of the relative magnetic permeability of feebly magnetic materials is often required to assess their effect on the ambient magnetic field. Typical feebly magnetic materials are austenitic stainless steels and "non-magnetic" brass. That said, for the application of soft magnetic materials, a large magnetic permeability is critical.
BS EN 60404-15 walks you through the procedure and calculations for the recommended methods and provides their respective relative magnetic permeability ranges.
Compliance with BS EN 60404-15 recommended tests can help assess the magnetic susceptibility of the materials, based on which you can select the right materials as per the specific application need. The right materials with improved permeability can enhance the performance, energy efficiency, and reliability of the product end-use.
