IEC(International Electrotechnical Commission)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 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 IEC also participate in this preparation.The IEC collaborates closely with the InternationalOrganization for Standardization(ISO)in accordance with conditions determined by agreement between thetwo organizations.2)The formal decisions or agreements of the IEC on technical matters express,as nearly as 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 specifications,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 standards.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 standards.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 61000-4-5 has been prepared by subcommittee 65A:Systemaspects,of IEC technical committee 65:Industrial-process measurement and control.It forms section 5 of part 4 of IEC 61000.It has the status of a basic EMC publication inaccordance with IEC Guide 107.This consolidated version of IEC 61000-4-5 is based on the first edition(1995),documents65A(CO)41+77B(CO)25 and 65A/168/RVD and its amendment1(2000)documents77B/291+293/FDIS and 77B/298+300/RVD.It bears the edition number 1.1.A vertical line in the margin shows where the base publication has been modified bythe corrigendum and amendment 1.Annex A forms an integral part of this standard.Annexes B and C are for information only.61000-4-51EC:1995+A1:2000-9-The committee has decided that the contents of the base publication and its amendment 1 willremain unchanged until 2003.At this date,the publication will bereconfirmed:withdrawn;replaced by a revised edition,or。amended.
