IEC 60794-1-23:2012

Optical fibre cables - Part 1-23: Generic specification - Basic optical cable test procedures - Cable element test methods

IEC 60794-23:2012 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 and is to define test procedures to be used in establishing uniform requirements for the geometrical, material, mechanical, environmental properties of optical fibre cable elements. This edition of IEC 60794-1-23 cancels and replaces the cable elements tests methods part of the second edition of IEC 60794-1-2 published in 2003. It constitutes a technical revision. Key words: Optical cable test procedures, optical fibre units

Câbles à fibres optiques - Partie 1-23: Spécification générique ‑ Procédures fondamentales d’essai des câbles optiques ‑ Méthodes d’essai des éléments de câble

IEC 60794-1-23: 2012 s’applique aux câbles à fibres optiques destinés à être utilisés avec des équipements de télécommunication et des dispositifs utilisant des techniques analogues, ainsi qu’aux câbles constitués de fibres optiques d’une part et de conducteurs électriques d’autre part.L’objet de la présente partie de l’IEC 60794 est la définition des procédures d’essai à utiliser pour établir des exigences uniformes relatives aux propriétés géométriques, mécaniques, de matériaux et d’environnement des éléments de câbles à fibres optiques. L’expression « câble optique » est utilisée dans tout le document et peut inclure des unités de fibres optiques, des unités de fibres en microconduits, etc. Les exigences générales et les définitions sont données dans l’IEC 60794-1-20 et un guide de référence complet pour tous les types de méthode d’essai est contenu dans l’IEC 60794-1-2.
Mots clés : Procédures d’essai des câbles optiques, unités de fibres optiques

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
