14、on)is a worldwide organization for standardization comprisingall national electrotechnical committees(IEC National Committees).The object of the IEC is to promoteinternational co-operation on all questions concerning standardization in the electrical and electronic fields.Tothis end and in addition
15、to other activities,the IEC publishes International Standards.Their preparation isentrusted to technical committees:any IEC National Committee interested in the subject dealt with mayparticipate in this preparatory work.International,governmental and non-governmental organizations liaisingwith the I
16、EC also participate in this preparation.The IEC collaborates closely with the International Organizationfor Standardization(ISO)in accordance with conditions determined by agreement between the twoorganizations.2)The formal decisions or agreements of the IEc on technical matters express,as nearly as
17、 possible,aninternational consensus of opinion on the relevant subjects since each technical committee has representationfrom all interested National Committees.3)The documents produced have the form of recommendations for international use and are published in the formof standards,technical specifi
18、cations,technical reports or guides and they are accepted by the NationalCommittees in that sense.4)In order to promote international unification,IEC National Committees undertake to apply IEC InternationalStandards transparently to the maximum extent possible in their national and regional standard
19、s.Anydivergence between the IEC Standard and the corresponding national or regional standard shall be clearlyindicated in the latter.5)The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment declared to be in conformity with one of its stand
20、ards.6)Attention is drawn to the possibility that some of the elements of this International Standard may be the subjectof patent rights.The IEC shall not be held responsible for identifying any or all such patent rights.International Standard IEC 61000-4-3 has been prepared by subcommittee 77B:High
21、frequency phenomenon,of IEC technical committee 77:Electromagnetic compatibility.This consolidated version of IEC 61000-4-3 is based on the second edition(2002)documents77B/339/FDIS and 77B/344/RVDand its amendment 1(2002)documents 77B/352/FDIS and77B/359/RVD1.It has the status of a basic EMC public
22、ation in accordance with IEC Guide 107.It bears the edition number 2.1.A vertical line in the margin shows where the base publication has been modified byamendment 1.Annex J forms an integral part of this standard.Annexes A to I as well as annex K are for information only.61000-4-3 IEC:2002+A1:2002-9-The committee has decided that the contents of this publication will remain unchanged until2005.At this date,the publication will bereconfirmed;withdrawn;.replaced by a revised edition,oramended.
