15、e 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 activ
16、ities, 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
17、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 determ
18、ined 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 Committ
19、ees. 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 t
20、hey 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 Publication
21、 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 responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that t
22、hey 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 injury, property damage or other damage of any nature
23、 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 cited in this publication. Use of the referenced p
24、ublications 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 identifying any or all such patent rights. The main task
25、 of IEC technical committees is to prepare International Standards. In exceptional circumstances, a technical committee may propose the publication of a technical specification when the required support cannot be obtained for the publication of an International Standard, despite repeated efforts, or
26、 The subject is still under technical development or where, for any other reason, there is the future but no immediate possibility of an agreement on an International Standard. Technical specifications are subject to review within three years of publication to decide whether they can be transformed
27、into International Standards. IEC 62398, which is a technical specification, has been prepared jointly by IEC technical committee 51: Magnetic components and ferrite materials, and the IEC Quality Assessment System for Electronic Components (IECQ-CECC). TS 62398 IEC:2004(E) 5 The text of this Techni
28、cal specification is based on the following documents: Enquiry draft Report on voting 51/765/DTS 51/785/RVC Full information on the voting for the approval of this technical specification can be found in the report on voting indicated in the above table. The QC number, which is the specification num
29、ber in the IECQ-CECC, is QC 210018. This publication has been partially drafted in accordance with the ISO/IEC Directives, Part 2 (2001). It also follows the requirements given in IEC QC 210000:1995, Technology Approval Schedules Requirements under the IEC Quality Assessment System for Electronic Co
30、mponents (IECQ-CECC), available on the IECQ-CECC web site www.iecq-cecc.org. The committee has decided 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 publica
31、tion. At this date, the publication will be transformed into an International standard, reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this Technical specification may be issued at a later date. 6 TS 62398 IEC:2004(E) International Electrotechnical Commissi

33、8 2004-10 TS 62398 IEC:2004(E) 7 INTRODUCTION The IEC Quality Assessment System for Electronic Components (IECQ-CECC) is composed of those member countries of the International Electrotechnical Commission (IEC) that wish to take part in a harmonized system for electronic components of assessed quali
34、ty. The object of the System is to facilitate international trade by the harmonization of specifications and quality assessment procedures for electronic components and by the granting of an internationally recognized mark or certificate of conformity. The components produced under the System are ac
35、ceptable in all member countries without further testing. This TAS has been prepared for use by those countries taking part in the System who wish to issue national harmonized specifications for Technology Approval of Manufacturers of ferrite cores. It should be read in conjunction with the current
36、regulations of the IECQ-CECC System. At the date of printing of this specification the member countries of IECQ-CECC are Austria, China, Denmark, Finland, France, Germany, India, Japan, Republic of Korea, Norway, Russian Federation, Thailand, United Kingdom, USA and Yugoslavia. Copies of this specif
37、ication can be obtained from their National Authorized institutions, National standard Organizations or, in case of difficulty, from the Central Office of IEC in Geneva, Switzerland (email infoiec.ch or fax 41 22 9190300) as described in the Specifications List QC 001004 (see www.iecq-cecc.org). The
38、 requirements for Technology Approval of manufacturers of electronic and electromechanical components are given in QC 001002-3, Clause 6. The procedures for approval defined in that Clause requires the manufacturer to have available an appropriate Technology Approval Schedule (TAS). This schedule de
39、fines how the principles and requirements of QC 001002-3, Clause 6 are applied to ferrite cores. In particular it defines minimum technical requirements which must be met by a manufacturer writing a Technology Approval Declaration Document (TADD) in accordance with Annex C of QC 001002-3, Clause 6.
