IEC 61753-111-07:2021

Fibre optic interconnecting devices and passive components - Performance standard - Part 111-07: Sealed closures - Category A - Aerial

IEC 61753-111-07:2021 contains the minimum tests, test severities and measurement requirements which a sealed fibre optic closure need to meet in order to be categorised as meeting the IEC standard for category A – Aerial, as defined in Table A.13 of IEC 61753‑1:2018. Free breathing closures are not covered in this document. This first edition cancels and replaces IEC 61753-111-7 published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 61753‑111‑7:  
terms and definitions updated according to IEC 61753-1:2018 and IEC 61756-1:2019;
detailed test severities added for UV light and fungus resistance tests of materials;
test severities updated according to IEC 61753-1:2018;
test overpressure for sealing tests changed to 20 kPa;

addition of B-657 fibre types with minimum bending radius of stored fibres according to IEC 61756-1:2019;
vibration sealing test changed to 10 Hz, 3 mm amplitude and 1 000 000 cycles;
reduced loads added in cable retention test for small diameter cables and tubes;
reduced loads for cable axial compression test for small diameter cables and tubes;

IEC 61753-111-07:2021 contient les essais minimaux, ainsi que les sévérités d’essai et les exigences de mesure minimales auxquels il est nécessaire qu’un boîtier à fibres optiques étanche satisfasse afin de pouvoir être classé comme satisfaisant à la norme IEC pour la catégorie A – Aériens, telle qu’elle est définie dans le Tableau A.13 de l’IEC 61753‑1:2018. Les boîtiers à ventilation libre ne sont pas couverts par le présent document. Cette première édition annule et remplace l’IEC 61753-111-7 parue en 2009. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'IEC 61753‑111‑7:
a. mise à jour des termes et définitions conformément à l’IEC 61753-1:2018 et à l’IEC 61756‑1:2019;
b. ajout des sévérités détaillées pour les essais de résistance des matériaux à la lumière UV et aux moisissures;
c. mise à jour des sévérités d’essai selon la nouvelle édition de l’IEC 61753-1:2018;

e. ajout du critère d’acceptation/de rejet de la perte de pression en cours d’essai aux essais d’étanchéité mécanique;
f. harmonisation des conditions d’essai en laboratoire avec l’IEC 61300-1 à une température de +23 °C ± 5 °C, sauf spécification contraire;
g. ajout des fibres de type B-657. rayon de courbure minimal des fibres stockées conformément à l’IEC 61756-1:2019;
h. modification de l’essai d’étanchéité aux vibrations (fréquence de 10 Hz, amplitude de 3 mm et 1 000 000 cycles);
i. ajout de charges réduites dans l’essai de rétention du câble pour les câbles et les tubes de petit diamètre;
j. ajout de charges réduites pour l’essai de compression axiale du câble pour les câbles et les tubes de petit diamètre;
k. ajout de la durée des cycles dans l’essai de torsion et de courbure;
l. suppression de l’essai de chute libre (couvert désormais par l'essai de choc optique);
m. réduction à 5 cycles de la durée d’essai de montage et de démontage;
n. réduction à 12 cycles de la durée de 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 Normati
