VERIFICATIONCOPYRIGHT IEC.FOREWORD1)The International Electrotechnical Commission(IEC)is a worldwide organization for standardization comprisingall national electrotechnical committees(IEC National Committees).The object of IEC is to promoteNOTinternational co-operation on all questions concerning standardization in the electrical and electronic fields.Tothis 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 IECPublication(s).Their preparation is entrusted to technical committees;any IEC National Committee interestedFORin 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 closelywith the International Organization for Standardization(ISO)in accordance with conditions determined byagreement between the two organizations.2)The formal decisions or agreements of IEC on technical matters express,as nearly as possible,an internationalconsensus of opinion on the relevant subjects since each technical committee has representation from allinterested IEC National Committees.3)IEC Publications have the form of recommendations for international use and are accepted by IEC NationalCommittees in that sense.While all reasonable efforts are made to ensure that the technical content of IECCOMMERCIAPublications is accurate,IEC cannot be held responsible for the way in which they are used or for anymisinterpretation by any end user.In order to promote international uniformity.IEC National Committees undertake to apply IEC Publicationstransparently to the maximum extent possible in their national and regional publications.Any divergencebetween any IEC Publication and the corresponding national or regional publication shall be clearly indicated inthe latter.USE5)IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment declared to be in conformity with an IEC Publication.号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 andmembers of its technical committees and IEC National Committees for any personal injury.property damage orother damage of any nature whatsoever.whether direct or indirect,orfor costs(including legal fees)and可other IECprising out of the publication.use of,of reliance upon,this EC Publication or any8)Attention is drawn to the Normative references cited in this publication.Use of the referenced publications isindispensable 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 ofpatent rights.IEC shall not be held responsible for identifying any or all such patent rights.International Standard IEC 62124 has been prepared by IEC technical committee 82:SolarUCTIONphotovoltaic energy systems.The text of this standard is based on the following documents:LONFDISReport on voting82/355/FDIS82/364/RVD0316Full information on the voting for the approval of this standard can be found in the report onvoting indicated in the above table.This publication has been drafted in accordance with the ISO/IEC Directives,Part 2.62124IEC:2004-9-The committee has decided that the contents of this publication will remain unchanged untilthe maintenance result date indicated on the IEC web site under http:/webstore.iec.chinthe data related to the specific publication.At this date,the publication will
