19、TECHNICAL COMMISSION _ FIXED INDUCTORS FOR ELECTROMAGNETIC INTERFERENCE SUPPRESSION Part 2-2: Blank detail specification Inductors for which safety tests are required (only) FOREWORD 1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising all
20、 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 and in addition to other activities, the IEC publishes International Standa
21、rds. 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 organizations liaising with the IEC also participate in this preparation. The IEC co
22、llaborates 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 matters express, as nearly as possible, an international consensus of op
23、inion 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 form of standards, technical specifications, technical reports or guides
24、 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 possible in their national and regional standards. Any divergence between the
25、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 declared to be in conformity with one of its standards. 6) Attention is dr
26、awn 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 IEC 60938-2-2 has been prepared by IEC technical committee 40: Capacitors a
27、nd 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 40/1113/FDIS 40/1139/RVD Full information on the voting for the approval
28、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 3. Annex A forms an integral part of this standard. 60938-2-2 IEC:1999 3
29、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. 4 60938-2-2 IEC:1999 FIXED INDUCTORS FOR ELECTROMAGNETIC INTERFERENCE SUPPRES
30、SION 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. It implements the approval schedule for safety tests only in IEC 60938-2,
31、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 comparison with IEC 60938-2-1 which provides safety tests and performance test
32、s, 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 approval and re- qualification tests contribute considerably to the costs of the
33、 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 specifications the content of 1.4 of the sectional specification shall be taken
34、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 specification and of the inductor The first page of the detail specification should
35、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 Organisation under whose authority the detail specification is drafted. 2 The IEC or
36、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 inductor 5 A short d

Alternativel
38、y, this drawing may be given in an annex to the detail specification, but should always contain an illustration of the general outer appearance of the inductor. 8 Reference data on the most important properties, to allow comparison between the various inductor types intended for the same, or for sim
