23、ctrotechnical 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 concerning standardization in the electrical and electronic fields
24、 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 as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC N
25、ational 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 preparation. IEC collaborates closely with the International Organization for Standardization
26、 (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 subjects since each technical committee has representati
27、on 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 content of IEC Publications is accurate, IEC cannot
28、 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 possible in their national and regional publications.
29、 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 certification bodies provide conformity assessment services and, in some areas, acces
30、s 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 liability shall attach to IEC or its directors, employees, servants or agents including indiv
31、idual 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 of the publication, use of, or reliance upon,
32、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
33、this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. The main task of IEC technical committees is to prepare International Standards. However, a technical committee may propose the publication of a technical report
34、 when it has collected data of a different kind from that which is normally published as an International Standard, for example “state of the art“. IEC 61200-52, which is a technical report, has been prepared by IEC technical committee 64: Electrical installations and protection against electric sho
35、ck. This second edition cancels and replaces the first edition, published in 1993, and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: 4 TR 61200-52 IEC:2013 a) the scope has been modified; whilst the Guide doe
36、s not form part of the IEC 60364 series, it serves as a supplement to IEC 60364-5-52:2009 and explains the rules so as to facilitate the design, selection, erection and maintenance of wiring systems; b) guidance associated with conduit systems, cable ducting systems, cable trunking systems, cable tr
37、ay systems and cable ladder systems has been added giving, for example, recommended maximum straight lengths of conduit to ease the installation circuit wiring; c) guidance associated with selection and erection of wiring systems in relation to external influences has been extended to cover impact,
38、and other mechanical stresses. d) guidance for grouping of cables has been added. e) guidance on maximum temperatures of terminals in normal service conditions has been extended; f) guidance on the connection of multi wire, fine wire and very fine wire conductors has been added; g) guidance on proxi
39、mity of communication cables has been added; h) guidance on cables in contact with thermal insulation has been added. This technical report serves as a supplement to IEC 60364-5-52:2009 and follows the numbering of that standard. The text of this technical report is based on the following documents:

43、n and maintenance of wiring systems. It is written for everyone concerned with the design, the selection and supply of equipment, as well as the persons who install, maintain and use electrical installations. 520.2 Normative references The following documents, in whole or in part, are normatively re
44、ferenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 60227-4, Polyvinyl chloride insulated cables of rated voltages up t
