Optical fibre cables - Part 1-20: Generic specification - Basic optical cable test procedures - General and Definitions

EN-IEC 60794-1-20 applies to optical fibre cables for use with telecommunication equipment and devices employing similar techniques, and to cables having a combination of both optical fibres and electrical conductors. The object of this standard is to define test procedures to be used in establishing uniform requirements for the geometrical, transmission, material, mechanical, ageing (environmental exposure) and climatic properties of optical fibre cables, and electrical requirements where appropriate. Throughout this standard the wording “optical cable” may also include optical fibre units, microduct fibre units, etc.

Câbles à fibres optiques - Partie 1-20: Spécification générique - Procédures fondamentales d’essais des câbles optiques - Généralités et définitions

L'IEC 60794-1-20:2014 s'applique aux câbles à fibres optiques destinés à être utilisés dans les équipements de télécommunications et les dispositifs utilisant des techniques analogues, ainsi qu'aux câbles constitués de fibres optiques d'une part et de conducteurs électriques d'autre part. La présente norme a pour objet de définir les procédures d'essai à utiliser pour établir des exigences uniformes relatives aux caractéristiques géométriques, de transmission, de matériaux, mécaniques, de vieillissement (exposition à l'environnement) et climatiques des câbles à fibres optiques, ainsi que des exigences électriques, le cas échéant. Tout au long de la présente norme, l'expression 'câble optique' peut également inclure des ensembles de fibres optiques, des ensembles de fibres pour microconduits, etc.   Mots clés: câbles à fibres optiques procédures d'essai, exigences uniformes

Optični kabli - 1-20. del: Splošne specifikacije - Osnovni preskusni postopki za optične kable - Splošno in definicije (IEC 60794-1-20:2014)

Ta del standarda EN-IEC 60794-1-20 obravnava optične kable za uporabo s telekomunikacijsko opremo in napravami, ki uporabljajo podobne tehnike, ter kable s kombinacijo optičnih vlaken in električnih vodnikov. Cilj tega standarda je določiti preskusne postopke za geometrijske, prenosne, materialne, mehanske, starostne (okoljska izpostavljenost) in klimatske lastnosti optičnih kablov in električnih zahtev, kjer je to ustrezno. V tem standardu lahko besedna zveza »optični kabel« zajema tudi optične enote, mikrokanale itd.

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 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
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 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 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 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
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
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 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 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
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 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 responsible for identifying any or all such patent rights.
International Standard IEC 60794-1-20 has been prepared by subcommittee 86A: Fibres and
cables, of IEC technical committee 86: Fibre optics.
This first edition of IEC 60794-1-20 cancels and replaces the general and guidance part of the
second edition of IEC 60794-1-2 published in 2003. It constitutes a technical revision.
It has been decided to split the second edition of IEC 60794-1-2 into six new documents:
– IEC 60794-1-2:2003, Optical fibre cables – Part 1-2: Generic specification – Basic optical
cable test procedures (second edition)
– IEC 60794-1-2:2013, Optical fibre cables –Part 1-2: Generic specification – Cross
reference table for optical cable test procedures (third edition)
– IEC 60794-1-20, Optical fibre cables – Part 1-20: Generic specification – Basic optical
cable test procedures – General and definitions
