Fibre optic interconnecting devices and passive components - Basic test and measurement procedures - Part 2-54: Tests - Corrosive atmosphere (mixed gas)

IEC 61300-2-54:2019 is to assess the corrosive effects of atmospheres polluted with mixed gas on fibre optic devices. It can be considered as a general corrosion test, but it does not predict the performance of a device in use.
Keywords: mixed gas on fibre optic devices

Dispositifs d'interconnexion et composants passifs fibroniques - Méthodes fondamentales d'essais et de mesures - Partie 2-54: Essais - Atmosphère corrosive (mélange de gaz)

IEC 61300-2-54:2019 a pour objet d'évaluer les effets corrosifs des atmosphères polluées par la présence d'un mélange de gaz sur des dispositifs fibroniques. Elle peut être considérée comme un essai général de corrosion, mais elle ne prévoit pas les performances d'un dispositif en fonctionnement.

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.

4 General description
This test

– is intended to assess the corrosive effects of atmospheres polluted with mixed gas on fibre

optic devices,
– is particularly suitable for giving information on a comparative basis, and

– can be considered as a general corrosion test, but it does not predict the performance of a

device in use.
---------------------- Page: 7 ----------------------
– 6 – IEC 61300-2-54:2019 © IEC 2019
5 Apparatus

The apparatus consists of a test chamber in accordance with IEC 60068-2-60, Test Ke. The

test chamber and its auxiliary parts shall be made of materials that do not react with or absorb

mixed gas and which do not influence the corrosive effects of the test atmosphere. The mixture

of air and mixed gas shall enter and leave the chamber through tubes with sufficiently large

diameters such that the total flow through the chamber is at least three, but not more than five,

changes of the atmosphere per hour. The exhaust from the chamber should not be allowed to

enter the laboratory.

The detailed construction of the chamber including the method of producing the test atmosphere

is optional, provided that

a) the conditions in that part of the chamber occupied by the device under tests (DUTs) are

within the specified limits,

b) the DUTs are protected from direct exposure to the individual incoming gas flows,

c) arrangements are made to move the DUTs through the test atmosphere at an average rate

of 0,0055 m/s to 0,0167 m/s (approximately 20 m/h to 60 m/h) or, alternatively, to gently stir

the atmosphere, obtaining a similar relative velocity between atmosphere and DUTs, and

d) condensation on the DUT does not occur inside the test chamber.
6 Procedure
6.1 Description of the DUT

Prepare the DUT according to the manufacturer’s instructions or as specified in the relevant

specification.

The DUTs shall be exposed mated connectors and unmounted devices as prescribed in the

relevant specification.

The DUTs shall be operational or not operational according to relevant specifications.

The DUTs shall be continuously exposed to the test atmosphere for the period specified in this

document (96 h).
6.2 Initial examination and measurement

The DUT shall be terminated with a sufficient length of fibre cable to facilitate connection with

the optical source and detector.

Prior to the tests, make the initial measurements and the initial visual examination as defined

in the relevant specification.
For visual examination, IEC 61300-3-1 applies.
For attenuation measurements, IEC 61300-3-4 applies.
For return loss measurements, IEC 61300-3-6 applies.
6.3 Preconditioning

Clean the mechanical and optical alignment parts of the DUT according to the manufacturer’s

instructions.
---------------------- Page: 8 ----------------------
IEC 61300-2-54:2019 © IEC 2019 – 7 –

Unless otherwise stated, maintain the DUT under standard atmospheric condition according to

IEC 61300-1 for 2 h minimum.
6.4 Conditioning

Attenuation and return loss measurements shall be performed when required by the relevant

specification.

Place the DUTs in the chamber in the normal operating position. Prior to the start of the test, it

shall be established by suitable measurements that stable conditions for the concentration of

mixed gas, the temperature and the relative humidity have been achieved. Periodic checks shall

be made during test to ensure that these conditions are maintained.

Care should be taken that the DUTs are so placed that they do not come into contact with one

another and that they do not shield one another from the test atmosphere.

Adequate precautions shall be taken to ensure that the DUTs are not disturbed during the

exposure period.
6.5 Recovery

Allow the DUT to remain under standard test conditions for 2 h minimum, as defined in

IEC 61300-1, unless otherwise specified in the relevant specification. Clean the optical surfaces,

but not the exterior surface that may have been corroded.
6.6 Final examinations and measurements
