IEC 61300-2-48:2009

Fibre optic interconnecting devices and passive components - Basic test and measurement procedures - Part 2-48: Tests - Temperature-humidity cycling

IEC 61300-2-48:2009 details a procedure for determining the suitability of a fibre optic device or closure to withstand variations in humidity and temperature that may occur during operation, storage and/or transport. The test is intended to indicate the performance of such devices when exposed to heat and humidity followed by short-term freezing. The main changes to this second edition are the addition of the Category O cycle procedure and the severity reconsideration.

Dispositifs d'interconnexion et composants passifs à fibres optiques - Méthodes fondamentales d'essais et de mesures - Partie 2-48: Essais - Cycles d'humidité et de température

IEC 61300-2-48:2009 précise une méthode pour déterminer l’aptitude d’un dispositif ou d’une terminaison à fibres optiques à résister aux variations d’humidité et de température susceptibles de se produire pendant le fonctionnement, le stockage et/ou le transport. L’essai est destiné à indiquer la performance de tels dispositifs lorsqu’ils sont exposés à la chaleur et à l’humidité suivies par une congélation de courte durée. En termes généraux, cet essai fournit une température élevée qui induit des défaillances potentielles du fait du ramollissement et de la dilatation, une humidité élevée pour favoriser l’absorption d’humidité et le gonflement, et une basse température pour faciliter la formation de glace, la fragilisation et la contraction. Cet essai diffère des autres essais d’environnement cycliques, en particulier l’essai de chaleur humide cyclique de l’IEC 61300-2-46 et l’essai cyclique composite de température et d’humidité de l’IEC 61300-2-21, par l’incorporation des niveaux alternatifs de sévérité. A cet effet:
a) le nombre de cycles est augmenté;
b) la plage de températures cycliques est élargie;
c) la période cyclique est réduite.
Cette seconde édition de l’IEC 61300-2-48 annule et remplace la première édition publiée en 2003, dont elle constitue une révision technique. L’ajout de la procédure de cycle de catégorie O et le réexamen de la sévérité constituent les principaux changements.
La présente version bilingue (2020-08) correspond à la version anglaise monolingue publiée en 2009-03.

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 61300-2-48 has been prepared by subcommittee 86B: Fibre optic
interconnecting devices and passive components, of IEC technical committee 86: Fibre optics.
This second edition of IEC 61300-2-48 cancels and replaces the first edition published in
