measurement techniques Immunity to conducted disturbances, induced by radio-frequency fields FOREWORD 1)The International Electrotechnical Commission(IEC)is a worldwide organization for standardization comprising lI national electrotechnical committees(IEC National Committees ). The object of 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, lEc publishes International standards. Technical Specifications Technical Reports, Publicly Available Specifications (PAS)and Guides (hereafter referred to as"IEC Publication()). 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 lEC 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 nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from al interested iec national committees 3IEC Publications have the form of recommendations for international use and are accepted by lEc Nati Com mittees in that sense while all reasonable efforts are made to ensure that the technical content of 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 lEc 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 5)IEC itself does not provide 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 latest 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 com mittees 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, or reliance upon, this IEc Publication or any other IEC Publications B) Attention is drawn to the normative references cited in this publication Use of the referenced publications is dispensable for the correct application of this publication 9 Attention is drawn to the possibility that some of the elements of this lEc Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights International Standard lEc 61000-4-6 has been prepared by subcommittee 77B: High frequency phenomena, of IEC technical committee 77: Electromagnetic compatibility It forms Part 4-6 of IEC 61000. It has the status of a basic EMC publication in accordance with IEC Guide 107 This fourth edition cancels and replaces the third edition published in 2008 and constitutes a technical revision This edition includes the following significant technical changes with respect to the previous edition a)use of the CDNs b)calibration of the clamps; c)reorganization of Clause 7 on test setup and injection methods; 6100046|EC:2013 d)Annex a which is now dedicated to EM and decoupling clamps e)Annex G which now addresses the measurement uncertainty of the voltage test level f)informative Annexes H, I and J which are new The text of this standard is based on the following documents FDIS Report on voting 77B/691FD|S 77B/704RvD 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/EC Directives, Part 2. A list of all parts in the IEC 61000 series, published under the general title Electromagnetic compatibility(EMC), can be found on the IEC website The committee has decided that the contents of this publication will remain unchanged until thestabilitydateindicatedonthelecwebsiteunderhttp://webstore.iecchinthedata 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 that it contains colours which are considered to be usefu for the correct understanding of its contents.
