15、ommission) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). 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 an

16、d in addition to other activities, the IEC publishes International Standards. 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 organizatio

17、ns liaising with the IEC also participate in this preparation. The IEC collaborates 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 the IEC on technical

18、 matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested National Committees. 3) The documents produced have the form of recommendations for international use and are published in the

19、 form of standards, technical specifications, technical reports or guides and they are accepted by the National Committees in that sense. 4) In order to promote international unification, IEC National Committees undertake to apply IEC International Standards transparently to the maximum extent possi

20、ble in their national and regional standards. Any divergence between the IEC Standard and the corresponding national or regional standard 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 d

21、eclared to be in conformity with one of its standards. 6) Attention is drawn to the possibility that some of the elements of this International 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 IE

22、C 60938-2-2 has been prepared by IEC technical committee 40: Capacitors and resistors for electronic equipment. This bilingual version (2013-05) 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

23、40/1113/FDIS 40/1139/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. The French version of this standard has not been voted upon. This publication has been drafted in accordance with the ISO/IEC Directives, Part

24、3. Annex A forms an integral part of this standard. EIA-60938-2-2 Page 2 The committee has decided that this publication remains valid until 2005. At this date, in accordance with the committees decision, the publication will be reconfirmed; withdrawn; replaced by a revised edition, or amended. EIA-

25、60938-2-2 Page 3 3 FIXED INDUCTORS FOR ELECTROMAGNETIC INTERFERENCE SUPPRESSION Part 2-2: Blank detail specification Inductors for which safety tests are required (only) INTRODUCTION Blank detail specification This blank detail specification forms the basis for a uniform procedure for a common mark.

26、 It implements the approval schedule for safety tests only in IEC 60938-2, requires a declaration of design for parameters relevant to safety tests and prescribes conformance tests to be conducted on every lot prior to its release and re-qualification tests depending on changes of the design. In com

27、parison with IEC 60938-2-1 which provides safety tests and performance tests, this specification is restricted to safety tests only. The use of IEC 60938-2-1 may be more appropriate for components manufactured in mass production, whereas this specification may be necessary in those cases where appro

28、val and re-qualification tests contribute considerably to the costs of the product. A blank detail specification is a supplementary document to the sectional specification and contains requirements for style and layout and minimum content of detail specifications. In the preparation of detail specif

29、ications 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 following information which shall be inserted in the position indicated. Identification of the detail specificat

30、ion and of the inductor The first page of the detail specification should have the layout recommended on the next page of this blank detail specification. 0 Manufacturers name. 0A Manufacturers style designation. 1 The “International Electrotechnical Commission“ or the National Standards Organisatio
