Overview

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. Special precautions are to be taken in measuring coercivities below 40 A/m, in materials withhigh conductivity and in test specimens which have a shape different from ellipsoids. Examples of magnetic materials covered by this document are amorphous alloys, nanocrystalline alloys, all soft magnetic crystalline materials (for example, Fe, FeSi-, CoFe- and FeNi-alloys), soft ferrites, hard metals, semi-hard magnetic alloys (for example, FeCoTiAl-, FeCoV-, FeCrCo- and AlNiCo-alloys).
