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
NEW!IEC 60404-6:2018 is available as IEC 60404-6:2018 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60404-6:2018 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.

Ta del standarda IEC 60404 določa metode merjenja AC magnetnih lastnosti mehkomagnetnih kovinskih materialov, razen elektropločevine in mehkoferitnih materialov, in sicer v frekvenčnem območju od 20 Hz do 100 kHz. Materiali, ki so zajeti v tem delu standarda IEC 60404, vključujejo posebne zlitine, navedene v standardu IEC 60404-8-6, amorfne in nano-kristalne mehkomagnetne materiale, stiskane in sintrane dele ter dele, oblikovane z brizganim litjem kovin, kot so navedeni v standardu IEC 60404-8-9, lite dele in mehkomagnetne kompozitne materiale.
Namen tega dela je opredeliti splošna načela in tehnične podrobnosti za merjenje magnetnih lastnosti mehkomagnetnih materialov z uporabo obročastih metod. Pri materialih v obliki praška se obročasti preskusni vzorec oblikuje z ustrezno metodo stiskanja.
Merjenje DC magnetnih lastnosti mehkomagnetnih materialov se izvede v skladu z obročasto metodo iz standarda IEC 60404-4. Določevanje magnetnih lastnosti mehkomagnetnih komponent se izvede v skladu s standardom IEC 62044-3.
OPOMBA: Standard IEC 62044-3:2000 določa metode za merjenje AC magnetnih lastnosti mehkomagnetnih komponent v frekvenčnem območju do 10 MHz.
Običajno se meritve opravijo pri sobni temperaturi (23 ± 5) °C na preskusnih vzorcih, ki so bili pred tem namagneteni in nato razmagneteni. Meritve se lahko po dogovoru zadevnih strank izvedejo v drugih temperaturnih območjih.

FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparen
