4 General description
WARNING − Intended users of this procedure are cautioned that tests of this nature may can
involve the use of certain hazardous material, operations and equipment. In particular, Some
of the fluids that may can be used are flammable or may can constitute health hazards, or both.
Test temperatures should shall 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
shall consult the relevant material’s safety data sheet of each used fluid and wear the
recommended personal protection clothing and equipment for handling highly toxic or
flammable products when necessary.
This test method covers the effects of contaminating fluids on the properties of fibre optic
interconnecting devices, passive components and closures protective housings when coming
in contact with fluids in an intentional or unintentional way. Testing is performed to ensure
resistance of a device under test (DUT) to liquids to which it could be exposed during storage,
installation or operation, and is carried out by immersing specimens in exposing the DUT to a
specified fluid or group of fluids for a specified period at a specified temperature. A separate
specimen DUT shall be used with each test fluid. Properties are measured prior to and after
exposure to the fluid.
This test method contains two procedures, procedure A and procedure B: 2
• Procedure A
DUT is immersed in a test fluid for 30 s, removed and then exposed to the test temperature
for the test duration specified in Table 1.
• Procedure B
DUT is immersed in a test fluid while being exposed for the test duration and to the test
temperature specified in Table 1.
The selected procedure shall be based on the relevant IEC 61753 performance standard.
5 Apparatus
5.1 Containers
A container made of a material that will not interact with the testing fluid shall be used for each
test fluid. Example materials for the test vessel are 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 DUT to be immersed until it is fully covered in the selected fluid
without violating other physical constraints (e.g. minimum cable bend radius).
5.2 Fluids
Fluids used shall be in accordance with the relevant specification for the fluid IEC 61753
performance standard or IEC 62005 reliability document 3. Table 1 give examples of fluids
that may be used for this evaluation; other liquids can be used by specific request. 4
5.3 Heat source
A suitable heat source capable of achieving and maintaining the specified temperatures within
±2 °C of the required setting shall be used.
5.4 Oven Temperature controlled equipment
A suitable oven to dry the specimen shall be used.
If the specified period for liquid exposure is longer than 1 h, or to dry the DUT after exposure,
a temperature-controlled oven or an environmental test chamber shall be used in order to keep
the test temperature stable. See 6.4 and 6.5.
6 Procedure
6.1 General DUT preparation
The preparation of the specimen DUT shall be in accordance with the relevant specification
IEC 61753 performance standard or IEC 62005 reliability document 5. If cables are fitted, they
shall be long enough to exit the test medium. Where no cables are fitted, blanking plugs shall
be inserted.
6.2 Preconditioning
Clean the mechanical and optical alignment parts of the specimen DUT according to the
manufacturer’s instructions.
Unless otherwise stated, maintain the specimen DUT under standard atmospheric condition
according to IEC 61300-1 for a minimum of 2 h.
6.3 Initial examinations and measurements
If specified, Perform initial examinations according to IEC 61300-3-1 and measurements as
required by the relevant specification IEC 61753 performance standard or IEC 62005 reliability
document.
For optical properties measurement, the equipment and measurement methods shall be
according to IEC 61300-3-4 for attenuation and IEC 61300-3-6 for return loss measurement.
The optical performance measurement shall be performed at the wavelength(s) specified in the
relevant IEC 61753 performance standard or IEC 62005 reliability document. When sealing
performance is requested to be evaluated, for devices such as sealed closures and hardened
connectors, the equipment and measurement method shall be according to IEC 61300-2-38 6.
For free breathing protective housings (that are not able to hold a permanent overpressure or
underpressure), the test shall be carried out on material slabs.
6.4 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.
6.4.1 Procedure A 7
For each specified fluid, prepare a vessel with sufficient fluid such that the DUT can be fully
immersed. Immerse the DUT for 30 s in the fluid, then remove the DUT from the fluid. For large
– 8 – IEC 61300-2-34:2024 CMV IEC 2024
DUTs or high viscosity fluids such as jellies, that are not practical to be immersed, brush the
test fluid homogeneously over the DUT external area. Drain-off the excess test fluid for 2 mins
and immediately after this step, set the DUT inside the temperature-controlled equipment to be
exposed to the test temperature and the period specified in Table 1.
DUTs of the same type and material, although exposed to different test fluids, can be placed
inside the same temperature-controlled equipment.
6.4.2 Procedure B 8
For each specified fluid, prepare a vessel with sufficient fluid such that the DUT can be fully
immersed.
Immerse the DUT while maintaining the fluid temperature during the period specified in Table 1.
This may require putting the vessel with the DUT immersed in temperature-controlled equipment.
In the case of volatile fluids, it is sometimes necessary to add fluid (heated to the test
temperature) during the test in order to keep the DUT immersed.
6.5 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.
6.5.1 Procedure A
After the exposure period at the designated test temperature, remove the DUT from the
temperature-controlled equipment and maintain it under standard atmospheric conditions
according to IEC 61300-1 for a minimum of 1 h.
6.5.2 Procedure B
At the end of the immersion period, remove the DUT and wipe off surplus fluid.
Dry the DUT in a temperature-controlled equipment at the temperature and period as defined
in Table 1. Remove the DUT from the temperature-controlled equipment and maintain it under
standard atmospheric conditions according to IEC 61300-1.
6.6 Final examinations and measurements
Upon completion of the test, the specimen DUT(s) shall be visually examined in accordance
with IEC 61300-3-1 and all necessary observations recorded as specified in the relevant
specification IEC 61753 performance standard or IEC 62005 reliability document. Careful
attention shall be given to Ensure no swelling and shrinkage of materials, loss of adhesive
bonding between bonded surfaces, corrosion of materials metallic parts, softening of materials,
cracks in material, degradation of optical characteristics, etc, have occurred.
The functional measurements shall should be accomplished taken at the standard test
atmospheric conditions as defined in IEC 61300-1, unless otherwise specified in the relevant
specification. When optical measurements are required, the equipment and measurement
methods shall be according to IEC 61300-3-4 for attenuation and 61300-3-6 for return loss
measurement. When sealing performance is evaluated, the equipment and measurement
method shall be according to IEC 61300-2-38.

List of comments
1 The object of this test method is to verify the effect of contaminating fluids on the device
under test as a whole and its functionality as part of a communications network.
2 Due to diversity of DUTs, sizes, handling and test conditions during the evaluation,
IEC 61300-2-34 edition 2 defines two test procedures that can be applied, depending on
the degree of simulated contamination on the DUT.
3 Fluids to be used have been reviewed and aligned with the general guidance for
performance of fibre optic interconnecting devices and passive components.
4 The fluids list includes those considered reflect actual risk of contamination during storage,
handling, installation or operation of interconnecting devices. Fluids that correspond to
other applications, e.g. avionics, have been removed from this document.
5 The IEC 62005 reference is an adequate guidance when extended period evaluation is
requested because of special applications or for new materials or products reliability
studies.
6 References to allow for quantitative base measurements and criteria for effects during and
after the evaluations are included.
7 Procedure A is convenient to evaluate interconnecting devices with permanent or long-term
exposure to contaminating fluid(s).
8 Procedure B is suitable to evaluate the effect of short-term exposure of interconnecting
devices to contaminating fluids.
9 In this new edition the severity for the evaluations are concentrated in a general table and
evaluation severities aligned to the operation category of the interconnecting device to be
evaluated. This minimizes the risk of applying a severity that does not correspond to a
specific element application.
10 Although the list of fluids covers the most used fluids in field and in the different stages of
handling and operation optical interconnecting devices may go through, there is the
possibility that a specific fluid or operation category can be requested for special
applications.

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

4 General description
WARNING − Intended users of this procedure are cautioned that tests of this nature can involve
the use of certain hazardous material, operations and equipment. Some of the fluids that can
be used are flammable or can constitute health hazards, or both. Test temperatures shall 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 shall consult the relevant material’s safety
data sheet of each used fluid and wear the recommended personal protection clothing and
equipment for handling highly toxic or flammable products when necessary.
This test method covers the effects on the properties of fibre optic interconnecting devices,
passive components and protective housings when coming in contact with fluids in an
intentional or unintentional way. Testing is performed to ensure resistance of a device under
test (DUT) to liquids to which it could be exposed during storage, installation or operation, and
is carried out by exposing the DUT to a specified fluid or group of fluids for a specified period
at a specified temperature. A separate DUT shall be used with each test fluid. Properties are
measured prior to and after exposure to the fluid.
This test method contains two procedures, procedure A and procedure B:
• Procedure A
DUT is immersed in a test fluid for 30 s, removed and then exposed to the test temperature
for the test duration specified in Table 1.
• Procedure B
DUT is immersed in a test fluid while being exposed for the test duration and to the test
temperature specified in Table 1.
The selected procedure shall be based on the relevant IEC 61753 performance standard.
5 Apparatus
5.1 Containers
A container made of a material that will not interact with the testing fluid shall be used for each
test fluid. Example materials for the test vessel are boro-silicate glass or stainless steel. Vessels
shall be of sufficient size and capacity to permit the DUT to be immersed until it is fully covered
in the selected fluid without violating other physical constraints (e.g. minimum cable bend
radius).
5.2 Fluids
Fluids used shall be in accordance with the relevant IEC 61753 performance standard or
IEC 62005 reliability document. Table 1 give examples of fluids that may be used for this
evaluation; other liquids can be used by specific request.
5.3 Heat source
A suitable heat source capable of achieving and maintaining the specified temperatures within
±2 °C of the required setting shall be used.
5.4 Temperature controlled equipment
If the specified period for liquid exposure is longer than 1 h, or to dry the DUT after exposure,
a temperature-controlled oven or an environmental test chamber shall be used in order to keep
the test temperature stable. See 6.4 and 6.5.
6 Procedure
6.1 DUT preparation
The preparation of the DUT shall be in accordance with the relevant IEC 61753 performance
standard or IEC 62005 reliability document. If cables are fitted, they shall be long enough to
exit the test medium. Where no cables are fitted, blanking plugs shall be inserted.
6.2 Preconditioning
Clean the mechanical and optical alignment parts of the DUT according to the manufacturer’s
instructions.
Unless otherwise stated, maintain the DUT under standard atmospheric condition according to
IEC 61300-1 for a minimum of 2 h.
6.3 Initial examinations and measurements
Perform initial examinations according to IEC 61300-3-1 and measurements as required by the
relevant IEC 61753 performance standard or IEC 62005 reliability document.
For optical properties measurement, the equipment and measurement methods shall be
according to IEC 61300-3-4 for attenuation and IEC 61300-3-6 for return loss measurement.
The optical performance measurement shall be performed at the wavelength(s) specified in the
relevant IEC 61753 performance standard or IEC 62005 reliability document. When sealing
performance is requested to be evaluated, for devices such as sealed closures and hardened
connectors, the equipment and measurement method shall be according to IEC 61300-2-38.
For free breathing protective housings (that are not able to hold a permanent overpressure or
underpressure), the test shall be carried out on material slabs.
6.4 Conditioning
6.4.1 Procedure A
For each specified fluid, prepare a vessel with sufficient fluid such that the DUT can be fully
immersed. Immerse the DUT for 30 s in the fluid, then remove the DUT from the fluid. For large
DUTs or high viscosity fluids such as jellies, that are not practical to be immersed, brush the
test fluid homogeneously over the DUT external area. Drain-off the excess test fluid for 2 mins
and immediately after this step, set the DUT inside the temperature-controlled equipment to be
exposed to the test temperature and the period specified in Table 1.
DUTs of the same type and material, although exposed to different test fluids, can be placed
inside the same temperature-controlled equipment.
– 8 – IEC 61300-2-34:2024 IEC 2024
6.4.2 Procedure B
For each specified fluid, prepare a vessel with sufficient fluid such that the DUT can be fully
immersed.
Immerse the DUT while maintaining the fluid temperature during the period specified in Table 1.
This may require putting the vessel with the DUT immersed in temperature-controlled equipment.
In the case of volatile fluids, it is sometimes necessary to add fluid (heated to the test
temperature) during the test in order to keep the DUT immersed.
6.5 Recovery
6.5.1 Procedure A
After the exposure period at the designated test temperature, remove the DUT from the
temperature-controlled equipment and maintain it under standard atmospheric conditions
according to IEC 61300-1 for a minimum of 1 h.
6.5.2 Procedure B
At the end of the immersion period, remove the DUT and wipe off surplus fluid.
Dry the DUT in a temperature-controlled equipment at the temperature and period as defined
in Table 1. Remove the DUT from the temperature-controlled equipment and maintain it under
standard atmospheric conditions according to IEC 61300-1.
6.6 Final examinations and measurements
Upon completion of the test, the DUT(s) shall be visually examined in accordance with
IEC 61300-3-1 and all necessary observations recorded as specified in the relevant IEC 61753
performance standard or IEC 62005 reliability document. Ensure no swelling and shrinkage of
materials, loss of adhesive bonding between bonded surfaces, corrosion of metallic parts,
softening of materials, cracks in material, degradation of optical characteristics, etc, have
occurred.
The functional measurements should be taken at the standard atmospheric conditions as
defined in IEC 61300-1. When optical measurements are required, the equipment and
measurement methods shall be according to IEC 61300-3-4 for attenuation and 61300-3-6 for
return loss measurement. When sealing performance is evaluated, the equipment and
measurement method shall be according to IEC 61300-2-38.
In the case of contamination, the disposal of contaminated water can be subject to local
regulations. Follow the recommendations and warnings indicated in IEC 61300-2-38.
7 Severity
7.1 General
The severity consists of a selection of the test fluid, exposure duration and the fluid exposure
temperature.
Table 1 shows the specified test severities in relation to the performance categories. It is
recommended to verify the test severities with the relevant IEC 61753 performance standards
or IEC 62005 reliability documents for the normative values.
