FOREWORD
The formal decisions or agreements of the IEC on technical matters, prepared by Technical
1)
Committees on which all the National Committees having a special interest therein are
represented, express, as nearly as possible, an international consensus of opinion on the
subjects dealt with.
They have the form of recommendations for international use and they are accepted by the
2)
National Committees in that sense.
In order to promote international unification, the IEC expresses the wish that all
3)
National Committees should adopt the text of the IEC recommendation for their national
rules in so far as national conditions will permit. Any divergence between the IEC recom-
mendation and the corresponding national rules should, as far as possible, be clearly
indicated in the latter.

4. General considerations
4.1 This standard contains a selection of environmental test methods
taken from other standards including IEC Publication 68.
4.2 The selected test methods have been found suitable for testing
components of an alarm system and have the necessary reproducibility
and severities suitable for this field of application.
For general guidance on environmental testing, reference should be
made to IEC Publication 68-1.
For specific guidance on the various environmental test methods used
in this standard, reference should be made to the description of the
relevant test.
4.3 Classification of tests
This standard specifies a range of test methods with a number of
test severities in order to cover the need for relevant tests for each
system component.
The aim of each test is characterized by allocation of the test to one
of the following two test classes:
a)
Class A - Operation tests
The object of a test in Class A is:
i)
to demonstrate the ability of the specimen to operate correctly
under the influence of the normal service environment and/or
ii)
to demonstrate the immunity of the specimen to false alarm
under the influence of a particular service environment.
The test specimen is exposed to an environment corresponding in
its effects to the normal service environment.
b) Class B - Accelerated tests
The object of a test in Class B is to demonstrate the ability of the
specimen to survive under the influence of an artificial environ-
ment more severe than the normal service environment.
The test specimen is subjected to exposures, which are intention-
ally more severe that the service environment, in order to give
information about the long-term stability.
---------------------- Page: 7 ----------------------

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.

INTRODUCTION
The IEC 60811 series specifies the test methods to be used for testing non-metallic materials
of all types of cables. These test methods are intended to be referenced in standards for
cable construction and for cable materials.
NOTE 1 Non-metallic materials are typically used for insulating, sheathing, bedding, filling or taping within cables.
NOTE 2 These test methods are accepted as basic and fundamental and have been developed and used over
many years principally for the materials in all energy cables. They have also been widely accepted and used for
other cables, in particular optical fibre cables, communication and control cables and cables for ships and offshore
applications.

1 Scope
This Part 410 of IEC 60811 gives the procedure for copper-catalyzed oxidative degradation of
a polyolefin, which is typically used for insulation in communication cables.
Full test conditions, such as temperature, duration, etc. and full test requirements are not
specified in this standard; it is intended that they should be specified by the standard dealing
with the relevant type of cable.

undated references, the latest edition of the referenced document (including any
amendments) applies.
IEC 60811-100:2012, Electric and optical fibre cables – Test methods for non-metallic
materials – Part 100: General
3 Terms and definitions
For the purposes of this document, the terms and definitions given in IEC 60811-100 apply.
4 Test method
4.1 General
The need for a manufacturer to monitor his cable production to ensure that it has adequate
resistance to oxidation is well established. The Oxidation Induction Time (OIT) test has been
found suitable for monitoring both raw materials and cables for compliance with this
requirement, once suitable materials have been selected. The OIT test is not suitable for the
selection of materials. For this purpose, long-term thermal ageing tests are preferred.
4.2 Apparatus
For the purposes of this test, the different equipment used is as follows:
a) A differential thermal analyser or differential scanning calorimeter, capable of heating at
rates of up to at least (20 ± 1) K/min and maintaining the test temperature isothermally
within 0,2 K and of automatic recording of differences in temperature (or differences in
heat transfer) between the sample and a reference material to the required sensitivity and
precision.
b) A recorder capable of displaying heat flow or temperature difference on the Y-axis, and
time on the X-axis. The time base shall be accurate to ± 1 % and be readable to 0,1 min.
c) A gas-selector switch and regulators for high-purity nitrogen and oxygen.
---------------------- Page: 8 ----------------------
60811-410 IEC:2012 – 7 –
d) An analytical balance capable of weighing 30 g, and readable and repeatable to ±0,1 mg.
e) Test pieces holders: aluminium holders, each of approximately 6 mm to 7 mm in diameter,
or of similar dimensions as supplied by the manufacturer of the instrument.
4.3 Sample and test pieces preparation
From a sample of the cable, prepare an appropriate number, e.g. four test pieces of different
colours, of approximately 4 mm length containing the core. The test pieces shall be cut from
an insulated core to yield 3 mg to 5 mg of insulating material.
Insert one test piece in an aluminium holder.
4.4 Test procedure
Before carrying out a test series, the instrument shall be calibrated and prepared as described
in Annex A.
Open valves on both the nitrogen and oxygen gas cylinders. Place the gas selector switch to
the nitrogen (N ) position and adjust the flow rate to (50 ± 5) ml/min using a flowmeter.
2
Place the prepared test piece holder (see 4.3) in the differential thermal analyser and an
empty aluminium holder in the reference position.
NOTE Crimping the test piece with a suitable aluminium or stainless steel screen is optional. It may provide a
better contact with the test piece holder.
Purge with nitrogen for 5 min. Check the flow rate and readjust to (50 ± 5) ml/min if required.
Set signal amplification and recorder sensitivity to the full scale pen deflection associated with
the exothermic reaction and set the temperature base at zero.
Set the heating rate to 20 K/min and start the programmed heating.
Continue heating until the specified test temperature, controlled to ± 1 °C, is reached.
Discontinue programmed heating and equilibrate the test piece to a constant temperature.
Start to record the thermogram. A test temperature of 200 °C has been found appropriate for
polyethylene. To simplify the procedure, it is allowed to omit the programmed pre-heating and
start directly at the test temperature.
Once temperature equilibrium has been established (steady recorder signal), change purge
gas to oxygen, and adjust the flow rate to (50 ±5) ml/min. Mark this point on the recorder. This
change-over point to oxygen purge is considered the zero time of the experiment (T ).
o
Continue the isothermal operation until maximum pen deflection is attained after
commencement of the oxidative exotherm as shown on the recorder (see Figure 1).
In the case of a multi-step exotherm, continue the isothermal operation until maximum pen
deflection occurs.
When the test is completed, turn off the recorder and switch the gas selector back to nitrogen.
Allow the differential thermal analyser to cool to the ambient temperature.
Repeat the entire test on a new test piece, three more times, thus generating a total of four
thermograms. The use of a fresh aluminium reference holder for each test piece is optional.

– 8 – 60811-410 IEC:2012
4.5 Measurements
Extend the recorded base line from time zero to beyond the oxidative exotherm. Extrapolate
the steepest part of the exotherm to intercept the extended baseline (see Figure 1).
The OIT shall be measured from zero to the smallest time interval practical, not exceeding
1 min.
5 Test report
The test report shall be in accordance with that given in IEC 60811-100.
