30、 tests for switch mode power supply units and transformers for switch mode power supply units FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of I

31、EC 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, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS

32、) and Guides (hereafter referred to as “IEC Publication(s)”). 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

33、 the IEC also Participate in this preparation. 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 IEC on technical matters express, as nea

34、rly as possible, an international consensus of opinion on the relevant subjects since 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 tha

35、t 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 they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committee

36、s undertake to apply IEC Publications transparently to the maximum extent possible 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 proce

37、dure 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 they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agen

38、ts 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 whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of,

39、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 publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some o

40、f 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. International Standard IEC 61558-2-16 has been prepared by IEC technical committee 96: Transformers, reactors, power supply units and similar p

41、roducts for low voltage up to 1 100 V. This first edition of IEC 61558-2-16 cancels and replaces IEC 61558-2-17, published in 1997. It constitutes a technical revision. This part has the status of a group safety publication in accordance with IEC Guide 104 (1997): The preparation of safety publicati

42、ons and the use of basic safety publications and group safety publications. 61558-2-16 IEC:2009 5 The text of this standard is based on the following documents: FDIS Report on voting 96/330/CDV 96/333/RVC Full information on the voting for the approval of this standard can be found in the report on

43、voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. This Part 2-16 is intended to be used in conjunction with the latest edition of IEC 61558-1 and its amendments. It is based on the second edition (2005) of that standard. This pa

44、rt supplements or modifies the corresponding clauses in IEC 61558-1, so as to convert that publication into the IEC standard: Particular requirements and tests for switch mode power supply units and transformers for switch mode power supply units. A list of all parts of the IEC 61558 series can be f

45、ound on the IEC website under the title: Safety of transformers, reactors, power supply units and similar products for supply voltages up to 1 100 V. Future standards in this series will carry the new general title as cited above. Titles of existing standards in this series will be updated at the ti

46、me of the next edition. Where a particular subclause of Part 1 is not mentioned in this part, that subclause applies as far as is reasonable. Where this part states “addition“, “modification“ or “replacement“, the relevant text of Part 1 is to be adapted accordingly. In this part, the following prin

47、t types are used: requirements proper: in roman type; test specifications: in italic type; explanatory matter: in smaller roman type. In the text of this part, the words in bold are defined in Clause 3. Subclauses, notes, figures and tables additional to those in Part 1 are numbered starting from 10

48、1; supplementary annexes are entitled AA, BB, etc. 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 publication. At this date, the pu

49、blication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. NOTE The attention of National Committees is drawn to the fact that equipment manufacturers and testing organizations may need a transitional period following publication of a new, amended or revised IEC publication in which to make products in accordance with the new requirements
