31、EMC) Part 4-4: Testing and measurement techniques Electrical fast transient/burst immunity test FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object o
32、f 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, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (
33、PAS) 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
34、with 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
35、 nearly 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
36、 that 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 Commi
37、ttees 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 itself does not provi
38、de any attestation of conformity. Independent certification bodies provide conformity assessment 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 late
39、st edition of this publication. 7) No liability shall attach to IEC or its directors, employees, 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, whet
40、her direct or indirect, or for costs (including legal fees) and expenses arising out of the 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 in
41、dispensable for the correct application of this publication. 9) Attention is drawn to the possibility 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 610
42、00-4-4 has been prepared by subcommittee 77B: High frequency phenomena, of IEC technical committee 77: Electromagnetic compatibility. It forms Part 4-4 of IEC 61000. It has the status of a basic EMC publication in accordance with IEC Guide 107, Electromagnetic compatibility Guide to the drafting of
43、electromagnetic compatibility publications. This third edition cancels and replaces the second edition published in 2004 and its amendment 1 (2010) and constitutes a technical revision. This third edition improves and clarifies simulator specifications, test criteria and test setups. 61000-4-4 IEC:2
44、012 5 The text of this standard is based on the following documents: FDIS Report on voting 77B/670/FDIS 77B/673/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
45、 the ISO/IEC Directives, Part 2. The list of all currently available parts of the IEC 61000 series, under the general title Electromagnetic compatibility (EMC), can be found on the IEC web site. The committee has decided that the contents of this publication will remain unchanged until the stability
46、 date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. IMPORTANT The colour inside logo on the cover page of this publication indicates
47、 that it contains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer. 6 61000-4-4 IEC:2012 INTRODUCTION IEC 61000 is published in separate parts, according to the following structure: Part 1: Gene
48、ral General considerations (introduction, fundamental principles) Definitions, terminology Part 2: Environment Description of the environment Classification of the environment Compatibility levels Part 3: Limits Emission limits Immunity limits (in so far as they do not fall under the responsibility
49、of the product committees) Part 4: Testing and measurement techniques Measurement techniques Testing techniques Part 5: Installation and mitigation guidelines Installation guidelines Mitigation methods and devices Part 6: Generic standards Part 9: Miscellaneous Each part is further subdivided into several parts, published either as international standards or as technical specificatio
