23、PPRESSION Part 2-1: Blank detail specification Inductors for which safety tests are required Assessment level D FOREWORD 1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees
24、). The object of the 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 activities, the IEC publishes International Standards. Their preparation is entrusted to technical committees; a
25、ny 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. The IEC collaborates closely with the International Organization for Sta
26、ndardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee
27、has representation from all interested National Committees. 3) The documents produced have the form of recommendations for international use and are published in the form of standards, technical specifications, technical reports or guides and they are accepted by the National Committees in that sens
28、e. 4) In order to promote international unification, IEC National Committees undertake to apply IEC International Standards transparently to the maximum extent possible in their national and regional standards. Any divergence between the IEC Standard and the corresponding national or regional standa
29、rd shall be clearly indicated in the latter. 5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with one of its standards. 6) Attention is drawn to the possibility that some of the elements of this Inter
30、national Standard may be the subject of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60938-2-1 has been prepared by IEC technical committee 40: Capacitors and resistors for electronic equipment. This bilingual version
31、(2014-01) corresponds to the monolingual English version, published in 1999-10. The text of this standard is based on the following documents: FDIS Report on voting 40/1112/FDIS 40/1138/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicate
32、d in the above table. The French version of this standard has not been voted upon. 60938-2-1 IEC:1999 3 This publication has been drafted in accordance with the ISO/IEC Directives, Part 3. The committee has decided that this publication remains valid until 2005. At this date, in accordance with the
33、committees decision, the publication will be reconfirmed; withdrawn; replaced by a revised edition, or amended. 4 60938-2-1 IEC:1999 FIXED INDUCTORS FOR ELECTROMAGNETIC INTERFERENCE SUPPRESSION Part 2-1: Blank detail specification Inductors for which safety tests are required Assessment level D INTR
34、ODUCTION 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 requirements may not be considered as b
35、eing 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 specification correspond to the fo
36、llowing 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 The IEC or National Standards number
37、 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 inductor 5 A short description of the type of
38、 inductor. 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 drawing may be given in an annex to the detail speci
39、fication. 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 inductor types. 60938-2-1 IEC:1999 5 1 IEC 60938-2-1XX 2 QC XXXXXXXXXXXX ELECTRONIC COMPONENTS OF ASSESSED IEC 60938-2-1 4 QUAL
