24、MENTS 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 standardization
25、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 entru
26、sted 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 Interna
27、tional 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 since ea
28、ch 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 content of I
29、EC 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 possible in th
30、eir 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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity assess
31、ment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employ
32、ees, servants or agents 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
33、publication, use of, 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 po
34、ssibility that some of 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 62041 has been prepared by Technical Committee 96: Transformers, reactors, power supply units a
35、nd combinations thereof. This second edition cancels and replaces the first edition published in 2003. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: the frequency range for tests according to IEC 61000-4-3
36、 has been extended above 1 GHz according to technologies used in this frequency area; the testing requirements according to IEC 61000-4-11 have been amended significantly; the inclusion of a clause on tests in series production; the inclusion of a new clause on measurement uncertainly, and the inclu
37、sion of requirements on DC power ports and telecommunication ports. 4 62041 IEC:2010 It has the status of a product family EMC standard in accordance with IEC Guide 107:2009, Electromagnetic compatibility Guide to the drafting of electromagnetic compatibility publications. The text of this standard
38、is based on the following documents: FDIS Report on voting 96/358/FDIS 96/367/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. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. T
39、his standard is to be used in conjunction with IEC 61558 series. In this standard, the following print types are used: requirements proper: in roman type; test specifications: in italic type; explanatory matter: in smaller roman type. In the text of this publication, the words in bold are defined in
40、 Clause 3 of this standard and in the IEC 61558 series. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the public
41、ation 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
42、which to make products in accordance with the new requirements and to equip themselves for conducting new or revised tests. It is the recommendation of the committee that the content of this publication be adopted for implementation nationally not earlier than 12 months from the date of publication.
43、 62041 IEC:2010 5 SAFETY OF TRANSFORMERS, REACTORS, POWER SUPPLY UNITS AND COMBINATIONS THEREOF EMC REQUIREMENTS 1 Scope This international product family standard applies to transformers, reactors, power supply units and combinations thereof covered by the IEC 61558 series of standards. This standa
44、rd deals with the electromagnetic compatibility requirements for emission and immunity within the frequency range 0 Hz - 400 GHz. No measurement needs to be performed at frequencies where no requirement is specified. Transformers, reactors, power supply units and combinations thereof delivered with
45、or incorporated in an appliance or equipment should follow the relevant EMC standard applicable to that appliance or equipment. However, this standard may be used as a guide to test the transformers, reactors, power supply units and combinations thereof separately before incorporating them in the ap
46、pliance or equipment. This EMC standard covers performance only. Other operations of the transformers, reactors and power supply units (e.g. simulated faults in the electric circuitry for testing purposes or functional safety due to the effects of the electromagnetic phenomena, or evaluation of huma
47、n being for exposure to electromagnetic fields (EMF) have not been taken into consideration in this standard. NOTE When EUT (Equipment under Test) is used, it covers transformers, reactors, power supply units and combinations thereof where applicable. This standard does not apply to: uninterruptible
48、 power supplies (UPS) covered by IEC 62040 series; power supply units covered by IEC 61204-3, (i.e. DC-DC converters, DC power and distribution equipment and power supply units for use in applications covered by IEC 60950-1, IEC 61010-1, IEC 60601-1, IEC 60065 and IEC 62368-1); power supplies and co
49、nverters for use with or in products covered by IEC 61347-1. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 61000-3
