EN 61646:2008 - 2 - Foreword The text of document 82/512/FDIS, future edition 2 of IEC 61646, prepared by IEC TC 82, Solar photovoltaic energy systems, was submitted
12、to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 61646 on 2008-06-01. This European Standard supersedes EN 61646:1997. EN 61646:2008 includes the following significant technical changes with respect to EN 61646:1997: The major change is in the pass/fail criteria. It no longer relie
13、s on meeting a plus/minus criterion before and after each test, but rather on meeting the rated power after all of the tests have been completed and the modules have been light-soaked. This was done to eliminate the technology-specific preconditioning necessary to accurately measure the changes caus
14、ed by the test. (Some modules lose power in light while others lose power during dark heat.) Since all modules must work after exposure to light, this seemed like a good approach and will streamline the test procedure, hopefully reducing the testing cost. updated normative references; added a defini
15、tion of “minimum value of maximum output power”; modified the wording in major visual defects to allow some bending and misalignment without failure; added requirements to the report from EN ISO/IEC 17025; removed the “Twist Test” as was done from EN 61215, since no one has ever failed this test; ma

18、ards; added bypass diode thermal test.

41、tion for standardization comprising all 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, IEC
42、 publishes International Standards, Technical Specifications, Technical 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
43、 may participate in this preparatory work. International, governmental and non-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 agr
44、eement 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 all interested IEC National Committees. 3) IEC
45、 Publications have the form of recommendations for international use and are accepted by 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 use
46、d or for any misinterpretation by any end user. 4) In order to promote international uniformity, 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 co
47、rresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have th
48、e 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 whatsoever
49、, 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 indispensable 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
