IEC 61300-2-18:2023

Fibre optic interconnecting devices and passive components - Basic test and measurement procedures - Part 2-18: Tests - Dry heat

IEC 61300-2-18:2023 is available as IEC 61300-2-18:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 61300-2-18:2023 details a procedure to determine the suitability of a fibre optic interconnecting device, passive component, splices or closure to withstand the environmental condition of extended high temperature that occur during operation, storage and/or transport. The test is intended to indicate the performance of such devices when exposed to heat of constant temperature over a given period. In general terms, this test provides a high temperature to induce potential failures due to softening and expansions. This procedure does not assess the ability of a device to operate during temperature variations; in this case, IEC 61300-2-22 is used. This third edition cancels and replaces the second edition published in 2005. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- terms and definitions updated according to IEC 61753-1:2018;
- test severities updated according to IEC 61753-1:2018;
- simplification of the combination of temperature and exposure time.

Dispositifs d'interconnexion et composants passifs fibroniques - Procédures fondamentales d'essais et de mesures - Partie 2-18: Essais - Chaleur sèche

IEC 61300-2-18:2023 est disponible sous forme de IEC 61300-2-18:2023 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.IEC 61300-2-18:2023 décrit une procédure destinée à déterminer l'aptitude d’un dispositif d’interconnexion fibronique, d’un composant passif fibronique, des épissures ou d'un boîtier fibronique à supporter des conditions d’environnement à haute température prolongée présentes 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 une chaleur avec une température constante sur une période donnée. En termes généraux, cet essai fournit une température haute qui induit des défaillances potentielles du fait du ramollissement et de la dilatation. Cette procédure ne vise pas à évaluer l’aptitude d’un dispositif à fonctionner pendant les variations de température; dans ce cas, c’est l’IEC 61300-2-22 qui s’applique. Cette troisième édition annule et remplace la deuxième édition parue en 2005. Cette édition constitue une révision technique. La présente édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente:
- les termes et définitions ont été mis à jour conformément à l’IEC 61753-1:2018;
- les sévérités d’essais ont été mises à jour conformément à l'IEC 61753-1:2018;
- une simplification de la combinaison de la température et de la durée de l’exposition a été effectuée.

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 61300-2-18 has been prepared by subcommittee 86B: Fibre optic interconnecting devices

BASIC TEST AND MEASUREMENT PROCEDURES –

Part 2-18: Tests – Dry heat



1 Scope
This part of IEC 61300 details a procedure to determine the suitability of a fibre optic
interconnecting device, passive component, splices or closure to withstand the environmental
condition of extended high temperature that occur during operation, storage and/or transport.
The test is intended to indicate the performance of such devices when exposed to heat of
constant temperature over a given period.
In general terms, this test provides a high temperature to induce potential failures due to
softening and expansions.

4 General description
This procedure is connected in accordance with IEC 60068-2-2, test Bb. The device under test
(DUT) is placed in an environmental chamber and subjected to a dry heat environment, which
is maintained at a given temperature for a specified duration, as defined in the relevant
specification. If required by the relevant specification, the attenuation of the DUT is monitored
throughout the duration of the test.
5 Apparatus
5.1 Environmental test chamber
The apparatus shall consist of an environmental chamber in accordance with IEC 60068-2-2,
test Bb. The chamber shall be capable of housing the DUT and of allowing to route the optical
fibre(s) of the DUT outside the chamber for connection to the optical measurement equipment.
It shall also be capable of maintaining the specified temperature within the specified tolerances.
Forced air circulation can be used to maintain homogeneous conditions. Care shall be taken to
ensure that the DUT is not directly exposed to the heating or cooling elements.
5.2 Optical measurement equipment
The optical source and detector for monitoring the attenuation and return loss shall comply with
those specified in IEC 61300-3-3.
