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 61300-2-34 has been prepared by subcommittee 86B: Fibre
optic interconnecting devices and passive components, of IEC technical committee 86:
Fibre optics.
This second edition cancels and replaces the first edition published in 1995. The main
changes from the previous edition are as follows: the procedure and severity have been
reconsidered.

Part 2-34: Tests –
Resistance to solvents and contaminating fluids
of interconnecting components and closures

1 Scope
The purpose of this part of IEC 61300 is for testing fibre optic interconnecting components
and closures. The object of this test is to define a standard test method to assess the
effects of short term exposure to fluids and lubricants on fibre optic interconnecting
components and closures.
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
3 General description
This test method covers the effects of contaminating fluids on the properties of fibre optic
interconnecting components and closures. Testing is performed by immersing specimens in
a specified fluid for a specified period at a specified temperature. A separate specimen
shall be used with each fluid. Properties are measured prior to and after exposure to the
fluid.
WARNING - Intended users of this procedure are cautioned that tests of this nature may
involve the use of certain hazardous material, operations and equipment. In particular, some
of the fluids that may be used are flammable or may constitute health hazards, or both. Test
temperatures should be at least 10 °C below the flashpoint of any fluid being used. Open
flame heat sources should not be used with any organic solvents. Test personnel should
consult the relevant material’s safety data sheets when necessary.
4 Apparatus
4.1 Containers
A boro-silicate glass or stainless steel vessel of suitable volume for each test fluid shall be
used. Vessels shall be of sufficient size and capacity to permit the specimen to be
immersed until it is fully covered in the selected fluid without violating other physical
constraints (e.g. minimum cable bend radius).
4.2 Fluids
Fluids used shall be in accordance with the relevant specification for the fluid.

– 6 – 61300-2-34 ã IEC:2009
4.3 Heat source
A suitable heat source capable of achieving and maintaining the specified temperatures
within ±2 °C of the required setting shall be used.
4.4 Oven
A suitable oven to dry the specimen shall be used.
5 Procedure
5.1 General
The preparation of the specimen shall be in accordance with the relevant specification. If
cables are fitted they shall be long enough to exit the test medium. Where no cables are
fitted blanking plugs shall be inserted.
5.2 Preconditioning
Clean the mechanical and optical alignment parts of the specimen according to the
manufacturer’s instructions.
Unless otherwise stated, maintain the specimen under standard atmospheric condition
according to IEC 61300-1 for 2 h minimum.
5.3 Initial examinations and measurements
If specified, perform initial examinations and measurements as required by the relevant
specification.
5.4 Conditioning
For each specified fluid, prepare a vessel with sufficient fluid such that the specimen can
be adequately immersed.
Immerse the specimen for the specified period while maintaining the fluid temperature.
NOTE In the case of volatile fluids, it may be necessary to add additional amounts of fluid (heated to the test
temperature) during the test in order to keep the specimen immersed.
5.5 Recovery
At the end of the immersion period, remove the specimen and wipe off surplus fluid.
Where applicable as defined in the relevant specification, dry components in an oven at an
appropriate temperature for a defined period.
5.6 Final examinations and measurements
Upon completion of the test, the specimen(s) shall be examined and all necessary
observations recorded as specified in the relevant specification. Careful attention shall be
given to swelling of materials, loss of adhesive bonding between bonded surfaces, corrosion
of materials, softening of materials, cracks in material, degradation of optical
characteristics, etc.
The functional measurements shall be accomplished at the standard test conditions as
defined in IEC 61300-1, unless otherwise specified in the relevant specification.

6 Severity
6.1 General
The severity consists of the combination of the fluid, exposure duration and the fluid
temperature. The severity shall be specified in the relevant specification.
The following preferred severities are non-mandatory severities which may be specified for
this procedure.
6.2 Exposure and drying duration
Specimen shall be exposed to the test for the following preferred duration:

1 h
24 h
5 days
7 days
1 month
After exposure specimen shall be recovered by drying applied according to the
temperatures given in the relevant specification and durations mentioned below.
Table 2 – Preferred drying durations
1 h
2 h
24 h
The dry out temperature should be at maximum temperature of the service environment.
6.3 Fuels, lubricants, hydraulic fluids, cleaning agents and moisture repellents and
anti-freeze agents
