21、RRITES Part 2: Reference of dimensions 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 ques

22、tions 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

23、(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 coll

24、aborates 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

25、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 ensur

26、e 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 transparently to

27、the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered re

28、sponsible for any equipment declared to be in conformity with an IEC Publication. 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 tech

29、nical 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

30、 Publications. 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 subje

31、ct of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60401-2 has been prepared by IEC technical committee 51: Magnetic components and ferrite materials. This second edition cancels and replaces the first edition published in

32、 2003. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: New ferrite core shapes “half pot core for inductive proximity switches and PM core” in accordance with IEC 62317 series have been added respe

33、ctively as Figure 13 and Figure 14 in Clause 5: core illustrations. 4 60401-2 IEC:2009 The text of this standard is based on the following documents: CDV Report on voting 51/943A/CDV 51/959/RVC Full information on the voting for the approval of this standard can be found in the report on voting indi

34、cated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts of IEC 60401 series, under the general title Terms and nomenclature for cores made of magnetically soft ferrites, can be found on the IEC website. The committee has deci

35、ded that the contents of this publication will remain unchanged until the maintenance result date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition,

36、or amended. 60401-2 IEC:2009 5 TERMS AND NOMENCLATURE FOR CORES MADE OF MAGNETICALLY SOFT FERRITES Part 2: Reference of dimensions 1 Scope This part of IEC 60401 presents a method for defining the designation nomenclature for the major physical attributes of soft ferrite core shapes. The purpose of

37、this standard is to facilitate uniform usage of dimensional characters by manufacturers, specifiers, and users when describing core dimensions on drawings, in tables, and on catalogue specification sheets. 2 Normative references The following referenced documents are indispensable for the applicatio

38、n of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 62317 (all parts), Ferrite cores Dimensions 3 General specifications Only upper case alphabetic character assignment

39、s shall be used. Only one character per dimension per ferrite piece shall be used. Characters 2B and 2D shall be used for core sets such as EP, PQ, Pot and RM. 4 Dimension descriptions Table 1 and Table 2 describe the alphabetic character assignments for the major dimensions of ferrite shapes. All o

40、ther minor core dimensions designations are left to the discretion of the specifier.
