DESCRIPTION

BS EN IEC 60404-7:2020


This standard BS EN IEC 60404-7:2020 Magnetic materials is classified in these ICS categories:
  • 29.030 Magnetic materials
  • 17.220.20 Measurement of electrical and magnetic quantities

This part of IEC 60404 specifies a method of measurement of the coercivity of magnetic materials in an open magnetic circuit.

This document is applicable to all magnetic materials with coercivities from 0,2 A/m to 160 kA/m.

NOTE Examples of magnetic materials covered by this document are amorphous alloys, nanocrystalline alloys, all softmagnetic crystalline materials (e.g. Fe, FeSi-, CoFe-and FeNi-alloys), soft ferrites, hard metals, semi-hard magnetic alloys (e.g. FeCoTiAl-, FeCoV-, FeCrCo-and AlNiCo-alloys) [1]. 1

Special precautions are to be taken in measuring coercivities below 40 A/m, in materials with high conductivity and in test specimens which have a shape different from ellipsoids (see Annex A).
