25、2010 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ CABLE GLANDS 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

26、is to promote international co-operation 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) a

27、nd 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 may participate in this preparatory work. International, governmental and non- governmental organizations liaising with t

28、he IEC also participate in this preparation. 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 nearl

29、y 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 Publications have the form of recommendations for international use and are accepted by IEC National Committees in that

30、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 for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees

31、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 corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any

32、 attestation of conformity. Independent 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 edi

33、tion 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 for any personal injury, property damage or other damage of any nature whatsoever, whether di

34、rect 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 Normative references cited in this publication. Use of the referenced publications is indispen

35、sable 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 responsible for identifying any or all such patent rights. International Standard IEC 62444 has

36、 been prepared by subcommittee 23A: Cable management systems, of IEC technical committee 23: Electrical accessories. The text of this standard is based on the following documents: FDIS Report on voting 23A/606/FDIS 23A/618/RVD Full information on the voting for the approval of this standard can be f

37、ound in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. NOTE The following print types are used: requirements: in roman type; test specifications: in italic type; notes: in small roman type. 62444 IEC:2010 5 The

38、committee has decided that the contents of this publication will remain unchanged until the stability 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

39、edition, or amended. 6 62444 IEC:2010 CABLE GLANDS FOR ELECTRICAL INSTALLATIONS 1 Scope This Standard provides requirements and tests for the construction and performance of cable glands. This standard covers complete cable glands as supplied by the manufacturer or the supplier responsible for placi

40、ng the product on the market. This standard does not cover cable glands for mineral insulated cables. This standard covers cable glands with IEC 60423 metric entry threads. This standard can be used as a guide for cable glands with other type of entry threads. NOTE Certain cable glands may also be u

41、sed “in Hazardous Areas.” Regard should then be taken of other or additional requirements necessary for the enclosure to be installed in such conditions, for example as specified in the IEC 60079 series. 2 Normative references The following referenced documents are indispensable for the application

42、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.
