Optical Fibre Cables - Part 1-215: Generic specification - Basic optical cable test procedures - Environmental test methods - Cable external freezing test, Method F15 (IEC 60794-1-215:2020)

This part of IEC 60794-1 defines test procedures to be used in establishing uniform
requirements for the environmental performance of
• optical fibre cables for use with telecommunication equipment and devices employing similar
techniques, and
• cables having a combination of both optical fibres and electrical conductors.
Throughout this document, the wording "optical cable" can also include optical fibre units,
microduct fibre units, etc.
This document defines a test standard to determine the ability of a cable to withstand the effects
of freezing water that can immediately surround the optical fibre cable sheath by observing any
changes in the physical appearance of the sheath, or in the measured cable optical attenuation.
Method F15A is a test standard to simulate freezing of the medium surrounding a buried cable,
as in wet earth or water. Method F15A is moved from method F15 in IEC 60794-1-22:2017
without any technical changes.
Method F15B is a test standard to simulate freezing of the medium surrounding an outside cable
in a rigid conduit (duct) which is made of rigid material, for example steel. Method F15B includes
the solution to prevent the cable from being crushed when experiencing freezing conditions in
a rigid conduit (duct) which are pressure absorber pads and any other suggested means of
cable protection.
A reference guide to test methods of all types as well as general requirements can be found in
IEC 60794-1-2.

Câbles à fibres optiques - Partie 1-215: Spécification générique - Procédures fondamentales d'essais des câbles optiques - Méthodes d’essais d’environnement - Essai de résistance au gel en extérieur des câbles, méthode F15 (IEC 60794-1-215:2020)

IEC 60794-1-215:2020 définit les procédures d’essai à utiliser pour définir des exigences harmonisées pour les performances environnementales:
- des câbles à fibres optiques destinés à être utilisés avec les équipements et dispositifs de télécommunications employant des techniques similaires; et
- des câbles combinant fibres optiques et conducteurs électriques.
Dans le présent document, le terme « câble optique » peut également englober les unités de fibres optiques, les unités de fibres en microconduit, etc. Le présent document définit une norme d’essai pour déterminer la capacité d’un câble à résister aux effets de l’eau gelée pouvant se situer au voisinage immédiat de la gaine d’un câble à fibres optiques, en observant les quelconques variations d’aspect physique de la gaine, ou les quelconques variations de l’affaiblissement mesuré sur le câble. La méthode F15A est une norme d’essai pour simuler le gel du milieu entourant un câble enfoui, par exemple de la terre humide ou de l’eau. La méthode F15A est déplacée de la méthode F15 de l’IEC 60794-1-22:2017 sans aucune modification technique. La méthode F15B est une norme d’essai pour simuler le gel du milieu entourant un câble extérieur dans un conduit (gaine) rigide fabriqué dans un matériau rigide, par exemple l’acier. La méthode F15B inclut la solution qui évite l’écrasement du câble lorsqu’il est soumis à des conditions de gel dans un conduit (gaine) rigide, qui consiste en des tampons d’absorption de la pression et les quelconques autres moyens de protection du câble suggérés. Un guide de référence répertoriant les méthodes d’essai de tous types, ainsi que les exigences générales, peut être consulté dans l’IEC 60794-1-2.

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 60794-1-215 has been prepared by subcommittee 86A: Fibres and

INTRODUCTION
This part of IEC 60794 defines a test method to determine the ability of a cable to withstand the
effects of freezing water that can immediately surround the optical fibre cable sheath by
observing any changes in the physical appearance of the sheath, or in the measured cable
optical attenuation. The cable external freezing test in a rigid conduit (duct) is an item of F15
under consideration in IEC 60794-1-22:2017.
This document includes method F15 of IEC 60794-1-22:2017 as F15A: Cable external freezing
test for a buried cable, as in wet earth or water. There is no technical change in F15A. F15B is
a new introduced method. The numbering of these tests continues the F-series numbering
sequence of IEC 60794-1-22:2017.
The number of IEC 60794-1-215 is in line with the new numbering system of test methods as
1
planned in IEC 60794-1-2 .
