30、AL COMMISSION _ CABLE CLEATS FOR ELECTRICAL INSTALLATIONS 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-op

31、eration 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, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to

32、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-governmental organizations liaising with the IEC also participate in this pr

33、eparation. 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 on technical matters express, as nearly as possible, an international co

34、nsensus 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 by IEC National Committees in that sense. While all reasonable effort

35、s 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 uniformity, IEC National Committees undertake to apply IEC Publication

36、s 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 itself does not provide any attestation of conformity. Indepe

37、ndent 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 have the latest edition of this publication. 7) No li

38、ability 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, whether direct or indirect, or for costs (in

39、cluding 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

40、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 61914 has been prepared by subcommittee 23A

41、: Cable management systems, of IEC technical committee 23: Electrical accessories. This second edition cancels and replaces the first edition published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previo

42、us edition: a) Additional declaration and test for lateral load retention depending on cleat mounting orientation with associated new figures; b) Additional declaration of the distance between the cable centres in any short-circuit test and associated new figures; c) Specification of the cable to be

43、 used in short-circuit testing and relaxation of the ambient temperature limits for the test; d) Additional requirement to photograph the short-circuit test arrangement before and after the test and to record more complete details of the cable used; BS EN 61914:2016IEC 61914:2015 IEC 2015 5 e) Revis

44、ed parameters for the test of resistance to UV light. This edition also includes the following editorial changes with respect to the previous edition: f) Revised and updated normative references and bibliography; g) Editorial clarification of definitions; h) Editorial clarification of procedures for

45、 selection of test samples and the testing of cleats designed for more than one cable; i) Relaxation of some mandrel material requirements; j) Clarification of the inspection requirements following a short-circuit test and adding the option of either a.c. or d.c. voltage testing following a second s

46、hort-circuit; k) Clarification that the resistance to corrosion test applies to all types of fixing; l) New cleat example illustration; m) Limitations of use of the formulae in Annex B added. The text of this standard is based on the following documents: FDIS Report on voting 23A/786/FDIS 23A/795/RV

47、D 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. In this standard, the following print types are used: requirements proper: in rom

48、an type; test specifications: in italic type; notes: in smaller roman type. 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“ in the data related to the specific publication. At th

49、is date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended.
