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 61753-111-9 has been prepared by subcommittee 86B: Fibre optic
interconnecting devices and passive components, of IEC technical committee 86: Fibre optics.
The text of this standard is based on the following documents:
FDIS Report on voting
86B/2906/FDIS 86B/2936/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

A list of all parts of IEC 61753 series, published under the general title Fibre optic
interconnecting devices and passive components – Performance standard, can be found on the
IEC website.
Future standards in this series will carry the new general title as cited above. Titles of existing
standards in this series will be updated at the time of the next edition.
The committee has decided that the contents of this publication will remain unchanged until the
maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

INTRODUCTION
Performance standards for closures define the requirements for standard optical performance
under a set of specified conditions. This part of IEC 61753 contains a series or a set of tests
and measurements with clearly stated conditions, severities and pass/fail criteria. The set of
tests are intended to be a basis to prove the product’s ability to satisfy the requirements of a
specific application, market sector or user group.
A product that has been shown to meet all the requirements of this performance standard may
be declared as complying with this performance standard. Products having the same
classification from one manufacturer that satisfy this performance standard will operate within
the boundaries set by the performance standard. There is no guarantee that products from
different manufacturers, having the same classification and which conform to the same
performance standard, will provide an equivalent level of performance when they are used
together.
Conformance with IEC environmental policy according to IEC Guide 109 and concerning the
need to reduce the impact on the natural environment of fibre optic closures during all phases
of their life – from acquiring materials to manufacturing, distribution, use, and end-of-life
treatment (i.e. re-use, recycling (recovery and disposal)) are not part of this standard, but will
be covered in the generic specification.
Conformance to a performance standard demonstrates that a product has passed a design
verification test. It is not a guarantee of lifetime assured performance or reliability. Reliability
testing must be the subject of a separate test schedule, where the tests and severities selected
are such that they are truly representative of the requirements of this reliability test programme.
Consistency of manufacture should be maintained using a recognised Quality Assurance
programme whilst the reliability of product should be evaluated using the procedures
recommended in IEC 62005 series.
Tests and measurements are selected from the IEC 61300 series.

1 Scope
This part of IEC 61753 contains the minimum test and measurement requirements and
severities which a sealed fibre optic closure must satisfy in order to be categorised as meeting
the IEC standard for category S – subterranean, as defined in Annex A of IEC 61753-1. Free
breathing closures are not covered in this standard.

4 General requirements
4.1 Storage, transportation and packaging
The classes of environmental conditions and their severities to which closures may be exposed
during transportation are defined in IEC 60721-3-2. Normal transportation time is considered to
be 30 days or less.
The product, in its original packaging, shall be suitable for normal public or commercial
transportation and storage in weather protected non-temperature controlled storage
environments.
4.2 Marking and identification
Marking of the closure and its package shall be according to IEC 62134-1.
Product marking and identification shall survive the storage and transportation.
Each test sample should contain the following information at a minimum:
– manufacturer’s identification mark or logo;
– product designation, model or type,
– one of the following: lot number, batch number, date (at least month and year) of production
or serial number;
– expiry date (at least year) if the product contains components with a limited shelf life.
4.3 Materials
For all applied materials, a Material Safety Data Sheet shall be made available upon request.
The materials of the closure and fibre management system shall be compatible with the other
materials or solvents that can come into contact with it, for example cable filling compounds
and degreasing agents.
All materials that can come in contact with personnel shall meet appropriate health and safety
regulations.
The effect of UV light on all polymeric materials that are directly exposed to the environment,
shall not adversely affect the product’s performance. UV test shall be according to ISO 4892-3
Mode 1 lamp type 2. The effect of UV light shall be determined by measuring a suitable
property (e.g. tensile strength) both before and after exposure of the material slabs.
Polymeric materials shall not support mould growth causing mechanical degradation of the
materials. Mould growth shall be tested according to IEC 60068-2-10. The effect of mould
growth shall be determined by measuring a suitable property (e.g. tensile strength) both before
and after exposure of the material slabs.
