26、es (IEC National Committees). The object of IEC 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 Re

27、ports, Publicly Available Specifications (PAS) and 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

28、 non-governmental organizations liaising with the 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 agreement

29、s of IEC on technical matters express, as nearly 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 a

30、re 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 be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote int

31、ernational uniformity, IEC National Committees 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

32、 the latter. 5) IEC itself does not provide any 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 us

33、ers 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 for any personal injury, property damage or ot

34、her 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 Normative references cited in this publication.

35、 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 responsible for identifying any or all such pate

36、nt 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 when it has collected data of a different kind from that which is normally published as an International Standard, for example

37、“state of the art“. IEC/TR 62222, which is a technical report, has been prepared by subcommittee 46C: Wires and symmetric cables, of IEC technical committee 46: Cables, wires, waveguides, r.f. connectors, r.f. and microwave passive components and accessories. This second edition cancels and replaces

38、 the first edition published in 2005. It constitutes a technical revision. The 2005 technical report was the first attempt in understanding the potential fire hazards concerning new installations where large quantities of data cable are involved. Although it is important to remember that data cables

39、 will probably not spontaneously combust and offices are still filled with other highly flammable products, the increase of “flood wiring” should be a building design concern. This second edition attempts to align all the installation guides found and further improve safety with fire and its possibl

40、e transmission. Projects that formed the TR 62222 IEC:2012 5 overall direction of the 2005 edition have been taken into account, enabling an overall general improvement of the document The text of this technical report is based on the following documents: Enquiry draft Report on voting 46C/959/DTR 4

41、6C/962/RVC Full information on the voting for the approval of this technical report 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. The committee has decided that the contents of this publication

42、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 edition, or amended. 6 TR 62222 IEC:2012 FIRE PERFORMANCE OF

43、 COMMUNICATION CABLES INSTALLED IN BUILDINGS 1 Scope This Technical Report provides recommendations for the requirements and test methods to be specified for the fire performance of communication cables when installed in buildings. The recommendations relate to typical applications and installation

44、practices for copper and optical cables in buildings. This Technical Report includes an assessment of the fire hazards presented by such installations, and describes fire scenarios that have been established and the appropriate cable fire performances to mitigate these hazards. ISO/IEC 14763-2 recom

45、mends installation methods which, together with this Technical Report, provide guidelines for improving safety during fire. The recommendations also take into account legislation and regulation applicable to the fire performance of cables, an assessment of known test methods and their ability to mea

46、sure the recommended fire performance. Power cables are usually segregated from communication cables for electrical safety and installed differently so they have not been addressed in this Technical Report. 2 Normative references The following documents, in whole or in part, are normatively referenc
