Optical fibres - Part 1-52: Measurement methods and test procedures - Change of temperature tests
IEC 60793-1-52:2014 provides a practical method for evaluating fibre performance in a defined environment. The purpose of this standard is to define a test that determines the suitability of sub-category A1a to A1d multimode fibres and class B and C single-mode fibres to withstand the environmental condition of change in temperature which may occur in actual use, storage and/or transport. The test is primarily intended to permit the observation of effects of change of temperature over a given period. This procedure is conducted in accordance with IEC 60068-2-14, Test Nb. This second edition cancels and replaces the first edition, published in 2001, and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- harmonizing the content with sectional specifications of relevant fibre types;
- extending the applicability of the document to class C single-mode fibres. Keywords: sub-category A1a to A1d multimode fibres, class B and C single-mode fibres, change in temperature
Fibres optiques - Partie 1-52: Méthodes de mesure et procédures d'essai - Essais de variations de température
IEC 60793-1-52:2014 présente une méthode pratique pour l'évaluation des performances des fibres dans un environnement défini. L'objet de la présente norme est de définir un essai pour la détermination de l'aptitude des fibres optiques multimodales de sous-catégories A1a à A1d et des fibres optiques unimodales de classes B et C à résister aux conditions d'environnement présentant des variations de température, susceptibles de survenir en utilisation réelle, pendant le stockage et/ou le transport. L'essai est essentiellement destiné à permettre l'observation des effets des variations de température pendant une période donnée. Cette procédure est appliquée conformément à l'IEC 60068-2-14, Essai Nb. Cette deuxième édition annule et remplace la première édition, parue en 2001, et constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- l'harmonisation du contenu avec les spécifications intermédiaires concernant les types de fibres correspondants;
- l'extension de l'applicabilité du document aux fibres unimodales de classe C. Mots clés: fibres optiques multimodales de sous-catégories A1a à A1d, fibres optiques unimodales de classes B et C, variations de température

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 60793-1-52 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 2001, and constitutes
a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
– harmonizing the content with sectional specifications of relevant fibre types;
– extending the applicability of the document to class C single-mode fibres.

voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all parts in the IEC 60793 series, published under the general title Optical fibres, can
be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,

This part of IEC 60793 provides a practical method for evaluating fibre performance in a
defined environment.
The purpose of this standard is to define a test that determines the suitability of sub-category
A1a to A1d multimode fibres and class B and C single-mode fibres to withstand the
environmental condition of change in temperature which may occur in actual use, storage
and/or transport. The test is primarily intended to permit the observation of effects of change
of temperature over a given period. This procedure is conducted in accordance with
IEC 60068
