Optical fibre cables - Part 1-23: Generic specification - Basic optical cable test procedures - Cable element test methods (IEC 60794-1-23:2019)

This Standard describes test procedures to be used in establishing uniform requirements for the geometrical, material, mechanical, environmental properties of optical fibre cable elements. This document 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. Throughout the document, the wording "optical cable" can also include optical fibre units, microduct fibre units, etc.

Câbles à fibres optiques - Partie 1-23: Spécification générique - Procédures fondamentales d’essai des câbles optiques - Méthodes d’essais d’éléments de câbles (IEC 60794-1-23:2019)

IEC 60794-1-23:2019 est disponible sous forme de IEC 60794-1-23:2019 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente. L'IEC 60794-1-23:2019 décrit les procédures d’essai à utiliser pour l’établissement d’exigences uniformes pour les propriétés géométriques, matérielles, mécaniques et environnementales des éléments de câble à fibres optiques. Le présent document 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. Dans le présent document, le terme "câble optique" peut également englober les unités de fibres optiques, les unités de fibres en microconduit, etc. Voir la IEC 60794-1-2 est le guide de référence des méthodes d’essai de tous types. Il doit être pris en considération pour les exigences générales et les définitions. Cette deuxième édition annule et remplace la première édition parue en 2012. Elle constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - ajout d’une nouvelle méthode d’essai G9: dégorgement et évaporation (précédemment connue en tant que méthode E15 dans l’IEC 60794-1-21:2015); - ajout d’une nouvelle méthode d’essai G10A: stabilité de la force de dénudage des fibres optiques câblées (précédemment connue en tant que méthode E5A dans l’IEC 60794-1-21:2015); - ajout d’une nouvelle méthode d’essai G10B: dénudabilité des rubans de fibres optiques (précédemment connue en tant que méthode E5B dans l’IEC 60794-1-21:2015); - ajout d’une nouvelle méthode d’essai G10C: dénudabilité des fibres optiques à revêtement protecteur (précédemment connue en tant que méthode E5C dans l’IEC 60794-1-21:2015); - ajout d’une nouvelle méthode d’essai G11A: résistance à la traction et allongement des tubes de protection (inclus à l’IEC 60811-501); - ajout d’une nouvelle méthode d’essai G11B: allongement des tubes de protection à basse température (inclus à l’IEC 60811-505); - clarification de la procédure de préparation des échantillons dans la méthode G5: déchirement des rubans (séparabilité).

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 60794-1-23 has been prepared by subcommittee 86A: Fibres and

cables, of IEC technical committee 86: Fibre optics.

This second edition cancels and replaces the first edition published in 2012. It constitutes a

technical revision.

This edition includes the following significant technical changes with respect to the previous

edition:
a) addition of a new test method G9: Bleeding and evaporation (formerly known as
method E15 in IEC 60794-1-21:2015);

b) addition of a new test method G10A: Stripping force stability of cabled optical fibres

(formerly known as method E5A in IEC 60794-1-21:2015);

c) addition of a new test method G10B: Strippability of optical fibre ribbons (formerly known

as method E5B in IEC 60794-1-21:2015);

d) addition of a new test method G10C: Strippability of buffered optical fibres (formerly known

as method E5C in IEC 60794-1-21:2015);
