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 61753-111-07 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 61753-111-7 published in 2009. This edition
constitutes a technical revision.This edition includes the following significant technical changes with respect to

INTRODUCTION
Performance standards for sealed closures define the requirements for standard optical
performance under a set of specified conditions. This subpart of the IEC 61753-111 series
contains a series or a set of tests and measurements with clearly stated conditions, severities
and pass/fail criteria. The set of tests is 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 impacts 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) – is not part of this document, 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 is 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 (all parts).---------------------- Page: 8 ----------------------
