Optical fibre cables - Part 1-211: Generic specification - Basic optical cable test procedures - Environmental test methods - Sheath shrinkage, method F11 (IEC 60794-1-211:2021)

This part of IEC 60794 defines test procedures to measure the shrinkage of the sheath due to
thermal exposure of cables.
A first test method, F11A, is included for cables where the fibre or buffered fibre and the sheath
of the cable are intended to be fully terminated into a connector at one or both cable ends.
A second test method, F11B, is included in this document for sheath shrinkage testing for
general purpose.
See IEC 60794-1-2 for a reference guide to test methods of all types and for general
requirements.

IEC 60794-1-211:2021 définit des procédures d’essai pour mesurer la rétraction de la gaine due à l’exposition thermique des câbles. Une première méthode d’essai, F11A, est incluse pour les câbles où la fibre ou la fibre sous revêtement protecteur et la gaine du câble sont destinées à être entièrement équipées d’un connecteur à l’une ou aux deux extrémités du câble. Une deuxième méthode d’essai, F11B, est incluse dans le présent document pour les essais de rétraction de la gaine des câbles destinés à un usage général. Voir l’IEC 60794-1-2 pour un guide de référence des méthodes d’essai de tous types et pour les exigences générales.

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.

IEC 60794-1-211 has been prepared by subcommittee 86A: Fibres and cables, of IEC technical

committee 86: Fibre optics. It is an International Standard.

This document partially replaces IEC 60794-1-22:2017. This edition constitutes a technical

revision.
This edition includes the following significant technical changes with respect
to IEC 60794-1-22:2017:

a) method F11 (cables intended for patch cords) of IEC 60794-1-22:2017 was renumbered

F11A and renamed as "sheath shrinkage (cables to be terminated with connectors)";

b) a second method F11B is newly included that was adapted from ANSI/TIA-455-86-A;

c) in method F11A, the thermal exposure from ambient to the specified temperature was

replaced by temperature cycling between a low and high temperature according to
IEC 60794-1-22, method F1;

d) in method F11A, the continuing of the test cycles until the shrinkage exhibits a variation less

than ±1 mm was replaced with a fixed number of cycles specified by the detail specification;

e) in method F11A, the average was changed to maximum sheath shrinkage that shall not

exceed the value specified in the relevant detail specification;

f) in both methods, the alternative that the sample may be cut to length and the length between

the cut sheath ends measured is added.
The text of this International Standard is based on the following documents:
