Note Although the intended primary application of this Standard is stated in its Scope, it is important to note that it remains the responsibility of the users of the Standard to judge its suitability for their particula

23、r purpose. DECEMBER 4, 2017 UL 61730-1 6UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL NATIONAL DIFFERENCES National Differences from the text of International Electrotechnical Commission (IEC) Publication IEC 61730-1 are indicated by notat

24、ions (differences) and are presented in bold text. There are ve types of National Differences as noted below. 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 Differenc

25、es based on the national regulatory requirements. D1 These are National Differences which are based on basic 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

26、 safety practices. These requirements reect national safety practices, where empirical substantiation (for 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 delet

27、ed until a particular component standard is harmonized with the IEC component standard. DE These are National 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

28、to explain how the text of the national difference is to be applied to the base IEC text: Addition / Add - 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 m

29、odication is an altering of the existing base IEC text such as the addition, replacement or deletion of 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,

30、subclause, table, gure, or annex without any replacement text.

31、rements for construction FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerni

32、ng standardization in the electrical and electronic elds. To this end and in addition to other activities, IEC publishes International Standards, Technical Specications, Technical Reports, Publicly Available Specications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their prepara

33、tion is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and nongovernmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with

34、 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 on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subje

35、cts 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 by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical

36、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 uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent po

37、ssible 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 itself does not provide any attestation of conformity. Independent certication bodies provide conform

38、ity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any 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

39、, 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, whether direct or indirect, or for costs (including legal fees) and expenses arising out

40、 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 t

41、o 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 61730-1 has been prepared by IEC technical committee 82: Solar photovoltaic energy syst

42、ems. This second edition cancels and replaces the rst edition of IEC 61730-1, issued in 2004, and its amendments 1 (2011) and 2 (2013); it constitutes a technical revision. DECEMBER 4, 2017 UL 61730-1 8UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION

43、 FROM UL This edition includes the following signicant technical changes with respect to the previous edition: a) Adaption of horizontal standards and inclusion of IEC 60664 and IEC 61140. b) Implementation of insulation coordination, overvoltage category, classes, pollution degree (PD), and materia

44、l groups (MG). c) Implementation of component qualication. d) IEC Guide 108 Guidelines for ensuring the coherency of IEC publications Application of horizontal standards. e) Denition of creepage (cr), clearance (cl) and distance through insulation. The text of this standard is based on the following

45、 documents: FDIS Report on voting 82/1128/FDIS 82/1146/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts in t

46、he IEC 61730 series, published under the general title Photovoltaic (PV) module safety qualication, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC website under http:/webstore.iec.ch

47、 in the data related to the specic publication. At this date, the publication will be reconrmed, withdrawn, replaced by a revised edition; or amended.
