27、or use in cords for controlled environment 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-operation on all

28、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 as “IEC Publica

29、tion(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 preparation. IEC

30、 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 consensus of opi

31、nion 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 efforts are made to

32、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 Publications transparentl

33、y 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. Independent certific

34、ation 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 liability shall

35、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 (including legal

36、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 of this public

37、ation. 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 60794-2-51 has been prepared by subcommittee 86A, Fibres

38、and cables,of IEC technical committee 86: Fibre optics. The text of this standard is based on the following documents: FDIS Report on voting 86A/1599/FDIS 86A/1607/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table.

39、This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts of IEC 60794 series, published under the general title Optical fibre cables, can be found on the IEC website. 4 IEC 60794-2-51:2014 IEC 2014 The committee has decided that the contents of this pu

40、blication 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. IMPORTANT The colour inside l

41、ogo on the cover page of this publication indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer. IEC 60794-2-51:2014 IEC 2014 5 OPTICAL FIBRE CABLES Part 2-51: Indoor cable

42、s Detail specification for simplex and duplex cables for use in cords for controlled environment 1 Scope This part of IEC 60794 is a detail specification. It gives detailed requirements for cables to be used in cords which are intended for use in a category C environment, according to IEC 61753-1. T

43、hey are characterized with temperature range between 10 C and +60 C. The fibre requirements for this specification are defined in IEC 60793-2-10 for multimode fibres and IEC 60793-2-50 for single-mode fibres. Some deviation to family specification IEC 60794-2-50 requirements is allowed in certain cl

44、auses of this specification. 2 Normative references The following documents, in whole or in part, are normatively referenced 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
