Optical fibres - Part 1-50: Measurement methods - Damp heat (steady state) tests (IEC 60793-1-50:2014)

This part of IEC 60793 provides a practical method for evaluating fibre performance in a
defined environment.
The purpose of this standard is to determine the suitability of optical fibre sub-category A1a to
A1d multimode fibres and class B and C single-mode fibres to withstand the environmental
condition of high humidity and high temperature which may occur in actual use, storage
and/or transport. The test is primarily intended to permit the observation of effects of high
humidity at constant temperature over a given period. This procedure is conducted in
accordance with IEC 60068-2-78, Test Cab.
NOTE The applicability of this test to other fibre categories is under study.

Fibres optiques - Partie 1-50: Méthodes de mesure - Essais de chaleur humide (état continu) (IEC 60793-1-50:2014)

L'IEC 60793-1-50:2014 présente une méthode pratique pour l'évaluation des performances des fibres dans un environnement défini. L'objet de la présente norme est de déterminer 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 une forte humidité et une température élevée, susceptibles de survenir en utilisation réelle, pendant le stockage et/ou le transport. L'essai est essentiellement destiné à permettre l'observation des effets d'une forte humidité à température constante pendant une période donnée. Cette procédure est appliquée conformément à l'IEC 60068-2-78, Essai Cab. Cette deuxième édition annule et remplace la première édition, publiée en 2001, dont elle 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: évaluation des performances des fibres, multimodales de sous-catégories catégories A1a à A1d,  des fibres optiques unimodales de classes B et C, humidité et une température élevée

Optična vlakna - 1-50. del: Metode merjenja - Preskusi vlažne toplote (ustaljeno stanje) (IEC 60793-1-50:2014)

Ta del standarda IEC 60793 zagotavlja praktično metodo za ocenjevanje delovanja vlaken v nadzorovanem okolju.
Cilj tega standarda je določiti ustreznost podkategorij večrodovnih optičnih vlaken A1a do A1d in enorodnih optičnih vlaken razredov B in C pri prenašanju okoljskih pogojev, kot sta visoka vlažnost in visoka temperatura, ki se lahko pojavita pri dejanski uporabi, shranjevanju in/ali prevozu. Preskus je prvenstveno namenjen omogočanju opazovanja učinkov visoke vlage pri stalni temperaturi v določenem časovnem območju. Ta postopek se izvaja v skladu s preskusom Cab iz standarda IEC 60068-2-78.
OPOMBA: Uporabnost tega preskusa za druge kategorije vlaken se še vedno preučuje.

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 accep
...
