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.

Long-term stability test of polyethylene and polypropylene compounds



1 Scope
This Part 408 of IEC 60811 gives the procedure to establish as to whether or not the quality of
a cable's components will be satisfactory over the proposed life of a communication cable.
This test is considered only as a material selection test to ensure that the chosen materials
are satisfactory for the intended life of the cable. The test duration makes the test unsuitable
for routine quality control testing; one method found suitable for monitoring raw materials is
given in IEC 60811-410.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and
are indispensable for its application. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any
amendments) applies.

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 Test method for unfilled cables
4.1.1 General
This part of IEC 60811 shall be used in conjunction with IEC 60811-100.
NOTE This test method is only applicable to communication cables containing copper pairs. A similar test method
applicable to electric cables for power distribution is under consideration.
The need to establish whether or not the quality of a cable's components will be satisfactory
over the proposed life of the cable is well recognized. In particular, polyolefin insulation shall
have sufficient resistance to ageing in service.
The definition of test duration, temperature, atmosphere and failure criteria shall be carefully
chosen.

---------------------- Page: 8 ----------------------
60811-408  IEC:2012 – 7 –
One of the two test conditions, differing in test temperatures and duration, shall be used
according to the severity of cable system conditions, as specified in the cable standard.
Condition A: Applies to insulations in cables or installations under moderate conditions
generally below 50 °C such as directly buried cables, cables in ducts or troughs, or cables
exposed above ground in temperate climates:
– 100 °C for 42 days.
Condition B: Applies to insulation in cables or installations in above-ground situations under
hot conditions, for instance cabinets or terminal boxes:
– 105 °C for 42 days.
4.1.2 Apparatus
For the purpose of this test, the different equipment used is as follows:
a) An air oven generally in accordance with ISO 188 and complying especially with the
following criteria:
– the mean temperature throughout the test shall be controlled to within ± 0,5 °C of the
specified temperature;
– the maximum variation of temperature throughout the test shall not exceed ± 1,0 °C of
the specified temperatures;
– exchange of clean, dry air: at least 6 changes of air per hour; in case of dispute, the
maximum rate of change shall be 10 changes per hour.
NOTE Alternatively, a test apparatus consisting of one or more cells having the following dimensions may be
used, provided that the above criteria are followed.
Cell height: at least 250 mm;
Cell diameter: at least 75 mm;
Height to diameter ratio: between 3:1 and 4:1.
b) An air flow meter with a measuring range dependent on the size of the air oven according
to a).
c) A thermocouple or thermometer allowing a resolution of not greater than 0,1 °C and total
measurement uncertainty not greater than 0,2 °C.
d) An analytical balance accurate to 0,5 mg and readable and repeatable to 0,1 mg.
4.1.3 Sample and test piece preparation
Three samples of each colour and 2 m in length shall be taken from a sample of unfilled
finished cable. They shall be subjected to the test described in Annex A, and shall satisfy the
requirement in Clause A.4.
At least three test pieces of 200 mm length shall then be cut from each sample that has been
tested as specified above. These test pieces shall be cut at equidistant intervals, the first
being taken at 200 mm from one end of the sample.
One end of each 200 mm length shall be wound manually around the other end to give at
least 10 contiguous turns. They shall be visually examined for cracks and splits.
4.1.4 Ageing procedure
The test pieces so formed shall be suspended in an air-circulating oven at (60 ± 2) °C for
seven days.

---------------------- Page: 9 ----------------------
– 8 – 60811-408  IEC:2012
4.1.5 Evaluation of the result
At the end of the treatment period the test pieces, when visually examined, shall be free from
cracks and splits.
4.2 Test method for fully filled cables
4.2.1 General
See 4.1.1.
For filled polyolefin insulated cables, compatibility of the combination of the insulation and
filling compound shall be assessed.
4.2.2 Apparatus
See 4.1.2.
4.2.3 Sample and test piece preparation
Three samples of each colour and 2,5 m in length shall be conditioned during seven days in
the associated filling compound at the following temperatures:
– (60 ± 2) °C for filling compounds having a drop-point above 50 °C and up to and including
70 °C;
– (70 ± 2) °C for filling compounds having a drop-point above 70 °C.
NOTE For an explanation of the drop-point, see IEC 60811-601.
Conditioning may be performed either on insulated cores by immersion in about 200 g of
filling compound (except for the ends) contained in a glass vessel, or on a cable. If a cable is
used, care shall be taken in removing the test pieces after conditioning.
After pre-conditioning, the samples shall be carefully wiped free of excess filling compound
using an absorbent lint-free tissue. The ends which were not immersed in the filling compound
shall be discarded, to obtain three samples of each colour and 2 m in length. These samples
shall be subjected to the test described in Annex A, and shall satisfy the requirement in
Clause A.4.
Then, at least three test pieces of 200 mm length shall be cut from the each sample that has
been tested as specified above. These test pieces shall be cut at equidistant intervals, the
first being taken at 200 mm from one end of the sample.
