6、ge.8 IEC 60904-2:2015 IEC 2015 3 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ PHOTOVOLTAIC DEVICES Part 2:Requirements for photovoltaic reference devices FOREWORD 1)The International Electrotechnical Commission(IEC)is a worldwide organization for standardization comprising all national electrotechnic
7、al 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,IEC publishes International Standards,Technical Specifications,Technic
8、al Reports,Publicly Available Specifications(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
9、-governmental organizations liaising 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
10、on technical matters express,as 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 b
11、y IEC National Committees in 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 unifor
12、mity,IEC National Committees 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 i
13、tself 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
14、 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 committees and IEC National Committees for any personal injury,property damage or other damage of any nature whatsoe
15、ver,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.8)Attention is drawn to the Normative references cited in this publication.Use of the referenced publications is ind
16、ispensable 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 60904-2 has been prepared by IEC Technical Committee 82:Solar photovoltaic energy systems.This third edition cancels and replaces the second edition,published in 2007.It constitutes a technical revision.The m
