27、OR DISTRIBUTION WITHOUT PERMISSION FROM UL NATIONAL DIFFERENCES National Differences from the text of International Electrotechnical Commission (IEC) Publication IEC 61730-2 are indicated by notations (differences) and are presented in bold text. There are ve types of National Differences as noted b

28、elow. The difference type is noted on the rst line of the National Difference in the standard. The standard may not include all types of these National Differences. DR These are National Differences based on the national regulatory requirements. D1 These are National Differences which are based on b

29、asic safety principles and requirements, elimination of which would compromise safety for consumers and users of products. D2 These are National Differences from IEC requirements based on existing safety practices. These requirements reect national safety practices, where empirical substantiation (f

30、or the IEC or national requirement) is not available or the text has not been included in the IEC standard. DC These are National Differences based on the component standards and will not be deleted until a particular component standard is harmonized with the IEC component standard. DE These are Nat

31、ional Differences based on editorial comments or corrections. Each national difference contains a description of what the national difference entails. Typically one of the following words is used to explain how the text of the national difference is to be applied to the base IEC text: Addition / Add

32、 - An addition entails adding a complete new numbered clause, subclause, table, gure, or annex. Addition is not meant to include adding select words to the base IEC text. Modication / Modify - A modication is an altering of the existing base IEC text such as the addition, replacement or deletion of

33、certain words or the replacement of an entire clause, subclause, table, gure, or annex of the base IEC text. Deletion / Delete - A deletion entails complete deletion of an entire numbered clause, subclause, table, gure, or annex without any replacement text. DECEMBER 4, 2017 UL 61730-2 7UL COPYRIGHT

34、ED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL INTERNATIONAL ELECTROTECHNICAL COMMISSION PHOTOVOLTAIC (PV) MODULE SAFETY QUALIFICATION Part 2: Requirements for testing FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organ

35、ization 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 elds. To this end and in addition to other activities, IE

36、C publishes International Standards, Technical Specications, Technical Reports, Publicly Available Specications (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 ma

37、y participate in this preparatory work. International, governmental and nongovernmental 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 agreeme

38、nt 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 Pub

39、lications 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 used or

40、 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 corres

41、ponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certication bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

42、 services carried out by independent certication bodies. 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 and members of its technical committees and IEC

43、National Committees for any personal injury, property damage or other damage of any nature whatsoever, 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) Attenti

44、on 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 the subject of patent rights. IEC

45、shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61730-2 has been prepared by IEC technical committee 82: Solar photovoltaic energy systems. This second edition cancels and replaces the rst edition of IEC 61730-2, issued in 2004 and its amendmen

46、t 1 (2011), and constitutes a technical revision. This edition includes the following signicant technical changes with respect to the previous edition: DECEMBER 4, 2017 UL 61730-2 8UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL a) Rearrange

47、 test sequences. b) MST 01: Visual inspection: added nameplate requirement and modied pass criteria. c) Added sharp edge test MST 06. d) Added insulation thickness test MST 04. e) MST 11: Accessibility test: dened force for test nger. f) MST 12: Cut susceptibility test: dened blade radius for cut te

48、st. g) MST 14: removed preconditioning requirement TC200 from Figure 1. h) MST 15: Partial discharge test removed. i) Renamed dielectric breakdown test MST 16 to insulation test. j) MST 21: Temperature test: rewritten test procedure; removed short circuit mode; allow alternative indoor test method.

49、k) MST 23: Fire test: subclause rewritten; re test requirements related to national building codes; moved optional test description to informative annex. l) Added ignitability test MST 24. m) MST 26: Reverse current overload test: changed specication of wooden board. n) MST 32: Module breakage test: dened new dimensions of impactor to allow other lling compounds; consider variety of mounting techniques for glass breakage test; reduced impact height to only 300 mm; corrected diamet
