28、ORD 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 concerning standardization in the elec

29、trical 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 as “IEC Publication(s)”). Their preparation is entrusted to tec

30、hnical 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 preparation. IEC collaborates closely with the International Orga

31、nization 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 subjects since each technica

32、l 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 content of IEC Publicat

33、ions 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 possible in their nationa

34、l 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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be i

35、n conformity with an IEC Publication. 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 National Committees

36、 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) Attention is drawn to the

37、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 shall not be held r

38、esponsible for identifying any or all such patent rights. International Standard IEC 61386-1 has been prepared by subcommittee 23A: Cable management systems, of IEC technical committee 23: Electrical accessories. This second edition cancels and replaces the first edition published in 1996, and its A

39、mendment 1 (2000), and it constitutes a technical revision. The changes to the first edition are as follows: change to the length of the test specimen between fittings for the tensile test, editorial and normative reference updates. 61386-1 IEC:2008 5 The text of this standard is based on the follow

40、ing documents: FDIS Report on voting 23A/553/FDIS 23A/558/RVDFull 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 the part

41、s in the IEC 61386 series, under the general title Conduit systems for cable management, can be found on the IEC website. This Part 1 is to be used in conjunction with the appropriate Part 2, which contains clauses to supplement or modify the corresponding clauses in Part 1, to provide the relevant

42、particular requirements for each type of product. A conduit system which conforms to this standard is deemed safe for use. In this publication, the following print types are used: Requirements proper: in roman type. Test specifications: in italic type. Explanatory matter: in smaller roman type. The

43、following differences exist in some countries: 6.5.2: In Australia and Austria, conduits and conduit fittings may be classified with low acid gas emission. 13.1.4: In Australia conduits and conduit fittings classified as low acid gas emission shall be tested in accordance with IEC 60754-1, evolve no

44、t more than the equivalent of 5 mg of hydrochloride-acid per gram of sample. In Austria conduits and conduit fittings classified as low acid gas emission shall be tested in accordance with IEC 60754-2. The committee has decided that the contents of this publication will remain unchanged until the ma

45、intenance result date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 6 61386-1 IEC:2008 CONDUIT SYSTEMS FOR CABLE MANAGEMENT Part 1:

46、General requirements 1 Scope This part of IEC 61386 specifies requirements and tests for conduit systems, including conduits and conduit fittings, for the protection and management of insulated conductors and/or cables in electrical installations or in communication systems up to 1 000 V a.c. and/or

47、 1 500 V d.c. This standard applies to metallic, non-metallic and composite conduit systems, including threaded and non-threaded entries which terminate the system. This standard does not apply to enclosures and connecting boxes which come within the scope of IEC 60670. NOTE 1 Certain conduit system

48、s may also be suitable for use in hazardous atmospheres. Regard should then be taken of the extra requirements necessary for equipment to be installed in such conditions. NOTE 2 Earthing conductors may or may not be insulated. 2 Normative references The following referenced documents are indispensab

49、le for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
