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 61300-2-33 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 2006. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous

Part 2-33: Tests – Assembly and disassembly of fibre optic
mechanical splices, fibre management systems and closures

1 Scope
This part of the IEC 61300 series, evaluates the assembly and reassembly of a fibre optic
mechanical splice, a fibre management system or a closure for a specified number of times.
The test procedures simulate the following conditions which may be encountered during the
component's service lifetime:
– the ability of an optical mechanical splice to be re-installed after disassembly;
– the ability to re-enter fibre management systems and closures, by accessing fibres and
optical components and making reconfigurations without disturbing transmission in adjacent
fibre circuits;
– verification of the sealing performance after frequent opening and closing of enclosures.

4 General description
Three test procedures are described. Procedure A tests the ability of optical mechanical splices
to be re-installed after disassembly. Procedure B tests the ability to re-enter fibre management
systems and closures, by accessing fibres and optical components and making
reconfigurations without disturbing transmission in adjacent fibre circuits. Procedure C verifies
the sealing performance after frequent opening and closing of enclosures.
The mechanical splice, fibre management system or (en)closure shall be assembled and
reassembled a specified number of times following the manufacturer's instructions, including
any specified cleaning or recovery procedure.
The test shall be done according to requirements referenced in IEC 61753-1. Assembly and
disassembly of the mechanical splice, fibre management system or closure shall be carried out
at room temperature, unless otherwise specified.
5 Procedure
5.1 Preparation of the specimen
Assembly tools and consumable materials, as specified by the manufacturer, shall be used.
5.2 Test procedures
5.2.1 Procedure A: Re-installation of an optical mechanical splice after disassembly
General description of the steps for Procedure A is defined as follows.
1) Assemble the mechanical splice according to the manufacturer's installation instructions
using the specified fibre or cable.
2) Perform any required examination and measurements as specified in the relevant
performance standard.
3) Perform the temperature ageing cycle as specified in the relevant performance standard.
When not specified, the ageing cycle as defined in Table 1 shall be used. After the
ageing cycle allow the specimen to recover at ambient temperature for at least 2 hours.
4) Disassemble the mechanical splice to the specified extent or to the point that all internal
fibres and devices can be accessed or removed.
5) Perform any specified cleaning and fibre preparation operations.
6) Re-install the mechanical splice according to the manufacturer's instructions.
7) Perform any required examinations and measurements as specified in the relevant
specification.
8) Repeat steps 3 through 7 for the number of cycles specified.
5.2.2 Procedure B: Optical stability during product reconfiguration
General description of the steps for Procedure B is defined as follows.

61300-2-33 © IEC:2012 – 7 –
1) Assemble the (en)closure or fibre management system according to the manufacturer's
instructions using the specified fibre or cable. An optical circuit is built as specified in
the performance standard.
2) Perform any required examination and measurements as specified in the relevant
performance standard. The change in attenuation in the optical circuit shall be
measured with the transient loss procedure, IEC 61300-3-28, when performing steps 3,
4 and 5.
3) The handling operations shall be performed as specified in the performance standard
(see Annex A for a typical example). The (en)closure shall be disassembled to the
specified extent or to the point that the internal fibres and devices can be accessed or
removed.
4) Perform the specified reconfiguration operations.
5) Close and secure the fibre management system and reassemble the (en)closure
according to the manufacturer's instructions.
5.2.3 Procedure C: Sealing performance after frequent opening and closing of the
enclosures
General description of the steps for Procedure C is defined as follows.
1) Assemble the (en)closure according to the manufacturer's installation instructions using
the specified fibre or cable.
2) Perform any required examination and check sealing performance as specified in the
relevant performance standard.
3) When specified in the performance standard, perform the specified temperature ageing
cycle. After the ageing cycle, allow the (en)closure to recover at ambient temperature
for at least 4 hours.
4) Disassemble the (en)closure to the specified extent or to the point that all internal fibres
and devices can be accessed or removed.
5) Re-install the (en)closure according to the manufacturer's installation instructions.
6) Perform any required examinations and check sealing performance as specified in the
relevant specification.
7) Repeat steps 3 through 6 for the number of cycles specified.
5.2.4 Ageing procedure
If specified in the relevant performance standard, the product shall be submitted to an aeging
process between assembly and disassembly operations. The major reason for the ageing
process is to speed up the creep of the polymeric materials in the alignment area or sealing
area after a re-entry is completed.
The purpose of the ageing procedure includes:
– identification of the design failures;
– identification of manufacturing defects;
– impact of product ageing on assembly and disassembly.
Table 1 shows ageing conditions. The ageing conditions are based on the operating
environmental conditions given in IEC 61753-1.
