23、n (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 ad
24、dition 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 inter
25、ested 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 wi
26、th 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
27、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 fo
28、r 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 the maximum extent possible in their national and regional publications. Any divergence between
29、 any IEC Publication 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 confo
30、rmity. IEC is not 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 membe
31、rs of its technical 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
32、 any other IEC 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 ma
33、y be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62317-2 has been prepared by technical committee 51: Magnetic components and ferrite materials. According to IEC 62317-1 clause 3-b) and Table A.1 in Annex A
34、, the publication number of IEC 60133 should be updated to IEC 62317-2 at the time of new revision of this standard. This first edition cancels and replaces the fourth edition of IEC 60133 published in 2000. This International Standard constitutes a technical revision of IEC 60133. The main changes
35、with respect to the previous edition of IEC 60133 are listed below: changed “e dimension” of P4,6/3,1 in Table 6 from 3,20 Max. to 3,40 Max.; removed “derived standards” from Annex B (informative) in the fourth edition of IEC 60133; 4 62317-2 IEC:2010 changed the name of core parts in Subclause 3.1.
36、2 from “Grooves” to “Wire-ways” in accordance with IEC 62317-1 Subclause 5.6. The text of this standard is based on the following documents: FDIS Report on voting 51/980/FDIS 51/982/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in
37、 the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts of the IEC 62317 series, under the general title Ferrite coresDimensions, can be found on the IEC website. The committee has decided that the contents of this publication will r
38、emain unchanged until the stability 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, or amended. 62317-2 IEC:2010 5 FERRITE CORES DIMENSIONS P
39、art 2: Pot-cores for use in telecommunications, power supply, and filter applications 1 Scope This part of IEC 62317 specifies the dimensions that are of importance for mechanical interchangeability for a preferred range of pot-cores made of ferrite, and the dimensional limits for coil formers to be
40、 used with them. The selection of core sizes for this standard is based on the philosophy of including those sizes which are industrial standards, either by inclusion in a national standard, or by broad-based use in industry. See IEC 62317-1 for more detail concerning the philosophy of selecting cor
41、e sizes to be included. The general considerations upon which the design of this range of cores is based are given in Annex A. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For u
42、ndated references, the latest edition of the referenced document (including any amendments) applies.
