14、nt level EZ 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 questions concerning standardiz

15、ation 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(s)”). Their preparation is

16、 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 collaborates closely with the

17、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 on the relevant subjects s

18、ince 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 ensure that the technical conte

19、nt 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 the maximum extent possibl

20、e 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 responsible for any equipmen

21、t 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 technical committees and IEC N

22、ational 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 Publications. 8) Attentio

23、n 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 of patent rights. IEC s

24、hall not be held responsible for identifying any or all such patent rights. International Standard IEC 60384-21-1 has been prepared by IEC technical committee 40: Capacitors and resistors for electronic equipment. This standard and its related publications (CEI 60384-21, IEC 60384-22 and IEC 60384-2

The text of this standard is based on the following documents: FDIS Report on voting 40/1421/FDIS 40/1452/RVD Full information on the voting for the appro

26、val of this standard can be found in the report on voting indicated in the above table. 4 60384-21-1 IEC:2004(E) This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. The committee has decided that the contents of this publication will remain unchanged until the mainte

27、nance 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, or amended. A bilingual version of this standard may be issued at a later date.

28、60384-21-1 IEC:2004(E) 5 INTRODUCTION Blank detail specification A blank detail specification is a supplementary document to the sectional specification and contains requirements for style, layout and minimum content of detail specifications. Detail specifications not complying with these requiremen

29、ts may not be considered as being in accordance with IEC specifications nor shall they so be described. In the preparation of detail specifications the content of 1.4 of the sectional specification shall be taken into account. The numbers between square brackets on the first page of the detail speci

30、fication correspond to the following information, which shall be inserted in the position indicated. Identification of the detail specification (1) The “International Electrotechnical Commission” or the National Standards Organization under whose authority the detail specification is drafted. (2) Th

31、e IEC or National Standards number of the detail specification, date of issue and any further information required by the national system. (3) The number and issue number of the IEC or national generic specification. (4) The IEC number of the blank detail specification. Identification of the capacit

32、or (5) A short description of the type of capacitor. (6) Information on typical construction (when applicable). (7) Outline drawing with main dimensions which are of importance for interchangeability and/or reference to the national or international documents for outlines. Alternatively, this drawin

33、g may be given in an annex to the detail specification. (8) Application or group of applications covered and/or assessment level. (9) Reference data on the most important properties, to allow comparison between the various capacitor types. 6 60384-21-1 IEC:2004(E) (1)IEC 60384-21-1-ZZZ QC 30XXXX-ZZZ
