25、2016 IEC 2016 3 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ OPTICAL FIBRE CABLES Part 3-20: Outdoor cables Family specification for self-supporting aerial telecommunication cables FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprisi
26、ng 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. To this end and in addition to other activities, IEC publishes International Standard
27、s, 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 National Committee interested in the subject dealt with may participate in this preparat
28、ory 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 (ISO) in accordance with conditions determined by agreement between the two organizati
29、ons. 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 representation from all interested IEC National Committees. 3) IEC Publications have the form of re
30、commendations 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 be held responsible for the way in which they are used or for any misinterpretation by
31、 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. Any divergence between any IEC Publication and the corresponding national or regional
32、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, access to IEC marks of conformity. IEC is not responsible for any services carried out by in
33、dependent 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 individual experts and members of its technical committees and IEC National Committees for a
34、ny 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 Normat
35、ive 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 respons
36、ible for identifying any or all such patent rights. International Standard IEC 60794-3-20 has been prepared by Subcommittee 86A: Fibres and cables, of IEC Technical Committee 86: Fibre optics. This third edition cancels and replaces the second edition published in 2009. It constitutes a technical re
37、vision. This edition includes the following significant technical changes with respect to the previous edition: a) the specification has been streamlined by cross-referencing IEC 60794-1-1, IEC 60794-1-2 and the IEC 60794-3 series; b) an annex containing the MICE table has been deleted; c) an annex
38、on examples has been added. BS EN 60794-3-20:2016 4 IEC 60794-3-20:2016 IEC 2016 The text of this standard is based on the following documents: FDIS Report on voting 86A/1733/FDIS 86A/1760/RVD Full information on the voting for the approval of this standard can be found in the report on voting indic
39、ated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts in the IEC 60794-3 series, published under the general title Optical fibre cables Part 3: Outdoor cables, can be found on the IEC website. The committee has decided that
40、the contents of this publication will remain unchanged until the stability date indicated on the IEC website 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. IMPORTA
41、NT The colour inside logo 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. BS EN 60794-3-20:2016IEC 60794-3-20:2016 IEC 2016 5 O
42、PTICAL FIBRE CABLES Part 3-20: Outdoor cables Family specification for self-supporting aerial telecommunication cables 1 Scope This part of IEC 60794, which is a family specification, covers optical self-supporting aerial telecommunication cables. Requirements of the sectional specification IEC 6079
43、4-3 for duct, buried and aerial cables are applicable to cables covered by this standard. Self-supporting aerial telecommunication cable in this context means a cable construction with sufficient strength members designed to be suspended on poles and similar devices without the aid of another suppor
44、ting wire or conductor. ADSS cables installed on power lines which require special sheath material for tracking and erosion resistance and other constructions intended for high-voltage applications are not covered by this standard. Detail specifications may be prepared based on this family specifica
45、tion. NOTE IEC TR 62839-1 gives rules to build an environmental declaration if needed. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
