24、 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ TERMS AND NOMENCLATURE FOR CORES MADE OF MAGNETICALLY SOFT FERRITES Part 3: Guidelines on the format of data appearing in manufacturers catalogues of transformer and inductor cores FOREWORD 1) The International Electrotechnical Commission (IEC) is a world
25、wide 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 ac
26、tivities, 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 subje
27、ct 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 dete
28、rmined 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 Commi
29、ttees. 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
30、 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 transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publicati
31、on and the corresponding national or regional publication shall 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
32、responsible for any services carried out by independent certification 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 technica
33、l committees and IEC National Committees for any personal injury, 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 Pub
34、lications. 8) Attention is drawn to the Normative references cited 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 o
35、f patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60401-3 has been prepared IEC technical committee 51: Magnetic components and ferrite materials. This second edition cancels and replaces the first edition published in 2003.
36、This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) addition of reliability in Clause 6. BS EN 60401-3:2016 4 IEC 60401-3:2015 IEC 2015 The text of this standard is based on the following documents:
37、 FDIS Report on voting 51/1106/FDIS 51/1121/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts in the IEC 6040
38、1 series, published under the general title Terms and nomenclature for cores made of magnetically soft ferrites, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC website under “http:/w
39、ebstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended.BS EN 60401-3:2016IEC 60401-3:2015 IEC 2015 5 INTRODUCTION For various reasons, a manufacturer may wish to publish in its catalogue
40、 typical data for material parameters as measured on test pieces. It is the object of this part of IEC 60401 to promote the comparability of such information in the area of soft ferrite materials. Except for several specific property limits that should be given separately for each particular core, t
41、he properties described in this standard are material characteristics, intended to facilitate meaningful evaluation of ferrite materials. It should be recognized, however, that there is no direct relation between material characteristics as measured on test pieces and the corresponding parameters me
42、asured on other cores, made of the same material, because of differences in geometry and variation in production processes. Also, the extrapolation of material characteristics to other flux densities and other frequencies will not permit valid comparison of cores of different materials under these n
43、ew conditions of operation. It is therefore emphasized that it is impossible to design and specify a core on the basis of material properties published by a manufacturer in its catalogue, without due contact with that manufacturer. Also, the publication of material characteristics should not be cons
44、idered as a guarantee for core properties; for this purpose, only the specification of that core should be used. It is strongly recommended that, together with the material characteristics, manufacturers publish a note covering the two statements above on the limitations of this kind of information.
45、 This standard further addresses the comparability of various grades of ferrite from different manufacturers by defining the baseline reliability and temperature performance that is inherent for all MnZn ferrite materials, and the limitations that exist when specifying related performance characteri
46、stics in ferrite cores. BS EN 60401-3:2016 6 IEC 60401-3:2015 IEC 2015 TERMS AND NOMENCLATURE FOR CORES MADE OF MAGNETICALLY SOFT FERRITES Part 3: Guidelines on the format of data appearing in manufacturers catalogues of transformer and inductor cores 1 Scope This part of IEC 60401 gives guidelines
47、for a uniform method of presentation for the properties of magnetically soft ferrite materials and measuring conditions under which they should be determined. It is intended for use in manufacturers catalogues of transformer and inductor cores, in order to aid the comparability of such data. Additio
48、nal guidance is given for users and manufacturers concerning testing and specification of reliability for ferrite cores and for devices using ferrite cores. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its
