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] .
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).dition 2.0 2019-01
