Magnetic materials - Part 6: Methods of measurement of the magnetic properties of magnetically soft metallic and powder materials at frequencies in the range 20 Hz to 100 kHz by the use of ring specimens

Edition date: 2021-07-05
In Force
Available languages: English, French
Summary: IEC 60404-6:2018+A1:2021 specifies methods for the measurement of AC magnetic properties of soft magnetic materials, other than electrical steels and soft ferrites, in the frequency range 20 Hz to 100 kHz. The materials covered by this part of IEC 60404 include those speciality alloys listed in IEC 60404-8-6, amorphous and nano-crystalline soft magnetic materials, pressed and sintered and metal injection moulded parts such as are listed in IEC 60404-8-9, cast parts and magnetically soft composite materials. The object of this part is to define the general principles and the technical details of the measurement of the magnetic properties of magnetically soft materials by means of ring methods. For materials supplied in powder form, a ring test specimen is formed by the appropriate pressing method for that material. The measurement of the DC magnetic properties of soft magnetic materials is made in accordance with the ring method of IEC 60404-4. The determinations of the magnetic characteristics of magnetically soft components are made in accordance with IEC 62044-3. This edition includes the following significant technical changes with respect to the previous edition:
a) adaption to modern measurement and evaluation methods, in particular the introduction of the widely spread digital sampling method for the acquisition and evaluation of the measured data;
b) limitation of the frequency range up to 100 kHz;
c) deletion of Clause 7 of the second edition that specified the measurement of magnetic properties using a digital impedance bridge;
d) addition of a new Clause 7 on the measurement of the specific total loss by the wattmeter method, including an example of the application of the digital sampling method;
e) addition of an informative annex on the technical details of the digital sampling technique for the determination of magnetic properties.
The contents of the corrigendum of November 2018 have been included in this copy.

IEC 60404-6:2018+A1:2021 spécifie les méthodes à utiliser pour mesurer les propriétés magnétiques en courant alternatif des matériaux magnétiques doux autres que les aciers électriques et les ferrites doux, aux fréquences comprises entre 20 Hz et 100 kHz. Les matériaux couverts par la présente partie de l'IEC 60404 incluent les alliages de spécialité répertoriés dans l'IEC 60404-8-6, les matériaux magnétiques doux amorphes et nanocristallins, les pièces compressées frittées et les pièces moulées par injection de métal répertoriées dans l'IEC 60404-8-9, ainsi que les pièces moulées et les matériaux composites magnétiquement doux. L'objet de la présente partie est de définir les principes généraux et les détails techniques de la mesure des propriétés magnétiques des matériaux magnétiquement doux au moyen des méthodes du tore. Pour les matériaux livrés sous forme de poudre, une éprouvette d'essai en forme d'anneau est réalisée à l'aide de la méthode de compression appropriée pour le matériau considéré. La mesure des propriétés magnétiques en courant continu des matériaux magnétiquement doux est réalisée selon la méthode du tore de l'IEC 60404-4. Les déterminations des propriétés magnétiques des composants magnétiquement doux sont réalisées selon l'IEC 62044-3. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) adaptation aux méthodes modernes de mesure et d'évaluation, notamment l'introduction de la méthode d'échantillonnage numérique largement répandue pour l'acquisition et l'évaluation des données mesurées;
b) limitation de la gamme de fréquences à 100 kHz;
c) suppression de l'Article 7 de la deuxième édition qui spécifiait la mesure des propriétés magnétiques à l'aide d'un pont d'impédance numérique;
d) ajout d'un nouvel Article 7 sur la mesure des pertes totales massiques par la méthode du wattmètre, y compris un exemple d'application de la méthode d'échantillonnage numérique;
e) ajout d'une annexe informative concernant les détails de la technique d'échantillonnage numérique pour déterminer les propriétés magnétiques du matériau.
