24、lectrotechnical 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 Spec

25、ifications, 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. Interna

26、tional, 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 form

27、al 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 fo

28、r 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

29、) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shal

30、l be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certif

31、ication bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal inju

32、ry, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references c

33、ited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identif

34、ying any or all such patent rights. International Standard IEC 60404-1 has been prepared by IEC technical committee 68: Magnetic alloys and steels. This third edition cancels and replaces the second edition published in 2000 and constitutes a technical revision. This edition includes the following s

35、ignificant technical changes with respect to the previous edition: a) Removal of all tables and values describing typical properties of the material to be consistent with the aim of the document to be a classification and not a specification. b) Enlargement of the Ni content for the classes E1 and E

36、3. c) Enlargement of the Co content for the classes F3. d) Addition of a new class: U5 bonded rare earth-iron-nitrogen magnets. IEC 60404-1:2016 IEC 2016 5 The text of this standard is based on the following documents: CDV Report on voting 68/533/CDV 68/555/RVC Full information on the voting for the

37、 approval of this International Standard can be found in the report on voting indicated in the above table. This document has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts in the IEC 60404 series, published under the general title Magnetic materials, can be foun

38、d on the IEC website. The committee has decided that the contents of this document will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific document. At this date, the document will be reconfirmed, withdrawn, replac

39、ed by a revised edition, or amended. A bilingual version of this publication may be issued at a later date. 6 IEC 60404-1:2016 IEC 2016 MAGNETIC MATERIALS Part 1: Classification 1 Scope This part of IEC 60404 is intended to classify commercially available magnetic materials. The term “magnetic mater

40、ials“ denotes substances where the application requires the existence of ferromagnetic or ferrimagnetic properties. In this document, the classification of magnetic materials is based upon the generally recognized existence of two main groups of products: soft magnetic materials (coercivity 1 000 A/

41、m); hard magnetic materials (coercivity 1 000 A/m). Within these main groups, the classification when appropriate recognizes the following characteristics: the main alloying element and the metallurgical state and physical properties of the material; when possible and convenient, the relationship be

42、tween these characteristics is identified. A classification by specific areas of application cannot be applied to all materials because different materials can very often be used for the same application depending on the characteristics required. 2 Normative references The following documents are re
