Fibre optic interconnecting devices and passive components - Basic test and measurement procedures - Part 2-7: Tests - Bending moment

IEC 61300-2-7:2013 details a procedure for determining the suitability of a fibre optic device to withstand the environmental condition of a bending moment which may occur in actual use, storage and/or transport. The test is primarily intended to permit the observation of effects of a bending moment. The bending moment may result in effects that would destroy functional utility, cause loss of physical strength, and cause changes in other important mechanical properties. Degradation of optical properties may also occur. The specimen may be a component, a connector set, a splice or other device combination intended for fibre optic usage. This second edition cancels and replaces the first edition published in 1995. It constitutes a technical revision.This edition includes the following significant technical changes with respect to the previous edition:
- a complete reconsideration of the entire document, including additional normative references;
- clarification of the device under test (DUT);
- clarification of the relationship between severities, performance categories and the DUT. Keywords: suitability of a fibre optic device to withstand the environmental condition of a bending moment

Dispositifs d'interconnexion et composants passifs à fibres optiques - Procédures fondamentales d'essais et de mesures - Partie 2-7: Essais - Moment de flexion

La CEI 61300-2-7:2013 décrit une méthode destinée à déterminer l'aptitude d'un dispositif à fibres optiques à supporter des conditions environnementales dans lesquelles peut intervenir un moment de flexion en cours d'utilisation, de stockage et/ou de transport. Cet essai a pour principal objectif de permettre l'observation des effets d'un moment de flexion. Le moment de flexion peut provoquer des effets de nature à affecter de manière importante le bon fonctionnement, à provoquer une perte de résistance physique et à causer des modifications d'autres propriétés mécaniques importantes. Une dégradation des propriétés optiques peut également se produire. Le spécimen peut être un composant, un jeu de connecteurs, une épissure ou une autre combinaison de dispositifs destinée à être utilisée avec des fibres optiques. Cette deuxième édition annule et remplace la première édition parue en 1995. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- un ré-examen complet de l'ensemble du document, y compris l'addition de nouvelles références normatives;
- la clarification du dispositif en essai (DUT);
- la clarification de la relation entre sévérités, les catégories de performance et le DUT. Mots clés: aptitude d'un dispositif à fibres optiques à supporter des conditions environnementales dans lesquelles peut intervenir un moment de flexion

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 61300-2-7 has been prepared by subcommittee 86B: Fibre optic
interconnecting devices and passive components, of IEC technical committee 86: Fibre optics.
This second edition cancels and replaces the first edition published in 1995. It constitutes a
technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) a complete reconsideration of the entire document, including additional normative
references;
b) clarification of the device under test (DUT);
c) clarification of the relationship between severities, performance categories and the DUT.

device to withstand the environmental condition of a bending moment which may occur in
actual use, storage and/or transport. The test is primarily intended to permit the observation
of effects of a bending moment. The bending moment may result in effects that would destroy
functional utility, cause loss of physical strength, and cause changes in other important
mechanical properties. Degradation of optical properties may also occur. The specimen may
be a component, a connector set, a splice or other device combination intended for fibre optic
usage.
