Magnetic materials - Part 7: Method of measurement of the coercivity (up to 160 kA/m) of magnetic materials in an open magnetic circuit

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).

Matériaux magnétiques - Partie 7: Méthode de mesure de la coercitivité (jusqu'à 160 kA/m) des matériaux magnétiques en circuit magnétique ouvert

La présente partie de l'IEC 60404 spécifie une méthode de mesure de la coercitivité des matériaux magnétiques en circuit magnétique ouvert. Le présent document est applicable à l'ensemble des matériaux magnétiques dont les valeurs de coercitivité sont comprises entre 0,2 A/m et 160 kA/m. NOTE Les alliages amorphes, les alliages nanocristallins, tous les matériaux magnétiques doux cristallins (par exemple, les alliages Fe, FeSi, CoFe et FeNi), les ferrites doux, les métaux durs, les alliages magnétiques mi-durs (par exemple, les alliages FeCoTiAl, FeCoV, FeCrCo et AlNiCo) sont des exemples de matériaux magnétiques couverts par le présent document [1]1. Des précautions particulières sont à prendre lors du mesurage des valeurs de coercitivité audessous de 40 A/m dans des matériaux qui présentent une conductivité élevée et dans des éprouvettes qui ont une forme différente des ellipsoïdes (voir Annexe A).
