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 61753-111-08 has been prepared by subcommittee 86B: Fibre optic interconnecting
devices and passive components, of IEC technical committee 86: Fibre optics. It is an
International Standard.
This first edition cancels and replaces IEC 61753-111-8 published in 2009. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to
IEC 61753-111-8:
a) terms and definitions updated according to IEC 61753-1:2018 and IEC 61756-1:2019;
b) test severities updated according to IEC 61753-1:2018;
c) sealing tests are done with 20 kPa overpressure;
d) pass-fail criterion of pressure loss during test added to mechanical sealing tests;
e) vibration sealing test changed to 10 Hz, 3 mm amplitude and 1 000 000 cycles;
f) reduced loads added in cable retention test for small diameter cables and tubes;
g) reduced loads for cable axial compression test for small diameter cables;
h) the duration of the cycles in torsion and bending test is added;
i) free fall test removed (is covered by the optical shock test);
j) crush resistance test of 1 000 N for 10 min is added;
k) assembly and disassembly test: duration reduced to 5 cycles;
l) resistance to solvents and contaminating fluids: added immersion in diesel with duration of
1 h and 24 h drying time and added immersion in petroleum jelly for 5 days;
m) resistance to stress cracking solvents added for 5 days;
n) duration of the change of temperature reduced to 12 cycles;
o) water immersion test at 1 m for 7 days added.
The text of this International Standard is based on the following documents:
