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 61300-2-17 has been prepared by subcommittee 86B: Fibre optic
interconnecting devices and passive components, of IEC technical committee 86: Fibre optics.
This third edition cancels and replaces the second edition published in 2003. This edition
constitutes a technical revision. The main changes with respect to the previous edition are
listed below:
a) Procedure and details to be specified were reconsidered.
b) The deviation of the temperature in severity was changed ± 3 °C to ± 2 °C.

voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
The list of all parts in the IEC 61300 series, published under the general title, Fibre optic
interconnecting and passive components – Basic test and measurement procedures, can be
found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until
the stability 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,

Part 2-17: Tests – Cold
1 Scope
This part of IEC 61300 details a procedure for determining the suitability of a fibre optic
device to withstand environmental conditions of extended low temperature (cold), which may
occur in use, storage and/or transport. This procedure does not assess the ability of a device
to operate during temperature variations; in this case, IEC 61300-2-22 would be used.
2 Normative references
The following referenced documents are indispensable for the application of this document.
For dated references, only the edition cited applies. For undated references, the latest edition
of the referenced document (including any amendments) applies.

IEC 61300-1, Fibre optic interconnecting devices and passive components – Basic test and
measurement procedures – Part 1: General and guidance
IEC 61300-3-1, Fibre optic interconnecting devices and passive components – Basic test and
measurement procedures – Part 3-1: Examinations and measurements – Visual examination
3 General description
This procedure is conducted in accordance with IEC 60068-2-1, test Ab. The Device Under
Test (DUT) is placed in a chamber at ambient temperature. The temperature is then lowered
to test temperature at a rate not exceeding 1 °C/min averaged over a maximum period of 5
min, and maintained at that temperature for the specified duration. The chamber temperature
is then raised to ambient and the DUT is allowed to attain ambient temperature before final
measurements are made.
4 Apparatus
4.1 Chamber
The apparatus is an environmental chamber in accordance with IEC 60068-2-1, test Ab. The
chamber shall be capable of housing the DUT and of allowing access for measurement during
conditioning, if required. It shall also be capable of maintaining the specified temperature and
tolerance. Forced air circulation may 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.
4.2 Other apparatus
Additional apparatus may be necessary to perform the measurements specified by the
relevant specification.
– 6 – 61300-2-17 Ó IEC:2010
4.3 Support for mounting the DUT
Unless otherwise specified in the relevant specifications, the thermal conductivity of the
supports for mounting the DUT shall be low, such that for practical purposes the DUT is
thermally isolated.
5 Procedure
5.1 General
Conduct the test according to the following procedure.
Unless otherwise specified in the relevant specification, the following applies:
– if the component construction includes optical leads, include 1,5 m of cable in the
environmental chamber for each port monitored during the test;
– if optical measurements are requested during the test by the relevant specification, these
measurements shall be performed at a maximum interval of 1 h.
5.2 Preconditioning
Unless otherwise stated in the relevant specification, maintain the DUT under standard
atmospheric conditions specified in IEC 61300-1 for a minimum of 2 h. Clean the mechanical
and optical alignment parts of the DUT according to the manufacturer's instructions.
5.3 Initial measurements
Complete initial examinations and measurements as required by the relevant specification.
5.4 Testing
a) Place the DUT in the chamber in its normal operating position and make connections to
the monitoring equipment.
b) Adjust the chamber temperature to the specified severity. The rate of change of
temperature shall not exceed 1 °C/min, averaged over a maximum period of 5 min. Allow
the DUT to reach temperature stability. The relevant specification may call for
measurements to be made during the test and will give details of how this should be done.
c) On completion of the test, allow
