Figure 2.2.2.3
A central longitudinal cut, perpendicular to the width of the test piece, shall be
made with a sharp razor to a point of 4 mm from the wider end.
(b) Procedure
Test each test piece in the following way. Place the halves of the split end in the
jaws of a tensile testing machine and separate the jaws at a rate of
(500 ± 5) mm/min.
The maximum load needed for the complete tearing of each test piece shall be
recorded.
(c) Evaluation of results
The tear resistance is determined by dividing the maximum load (in N) by the
thickness of the test piece (in mm).
The mean value of the results obtained shall be in accordance with the
requirements in the particular specification.
Subclause 2.2.8.6
Replace the third paragraph with the following:
Make two parallel cuts separated by (13 ± 1) mm in the semi-conducting insulation screen
material, down to the insulation and longitudinally from end to end of the core sample.
Remove approximately 50 mm length of the 13 mm strip from each end of the core by
manually pulling it away from the core.
Mount the sample in a tensile test machine, with one end of the strip clamped in the upper
jaws, and with the sample held horizontally at approximately 90º to the clamped strip.
Measure the force to separate the 13 mm strip whilst maintaining the strip at approximately
90º to the sample, using a pulling speed of approximately 8 mm/s. Continue until
approximately the midpoint of the sample.
Repeat the test from the other end of the sample.

A sample of the cable with a length of at least five times the test drum diameter shall
be subject to the partial discharge test in accordance with 3.10.3. The sample shall
then be cooled to 0°C for at least 4 h.
The sample shall then, without delay, be bent around a test cylinder, for at least one
complete turn. It shall then be unwound and the process repeated after rotating the
sample through 180° about its axis.
The sample shall be bent at a reasonably uniform speed, each half cycle of the test
taking approximately 1,0 s per millimetre of overall cable diameter.
The diameter of the test cylinder shall be not greater than 20(D + d) mm, where D is
the overall diameter of the cable and d is the conductor diameter as detailed in the
cable specification.
The sample shall then again be subjected to the partial discharge test in accordance
with 3.10.3.
The insulation, lead alloy sheath and oversheath shall then be visually examined.

shall be of 90º. The mass of the conic piece shall be as given in the particular
specification.
The conic surface shall not be rough.
The conic piece shall be subjected to a to-and-fro motion, at constant speed,
between the A and B marks, (see figure 2.4.22).

Subclause 2.4.23
Introduce new subclause as follows:
2.4.23 Resistance to UV rays
(a) Test principle and definition of the light source
This test is based on the prolonged exposure of the flat surface of the outer
side of the cable test specimens to ultra-violet rays.
The light source used should be such that in a dry atmosphere (relative
humidity below 30%) the exposed surface of the two flat surfaces of the test
specimen, the side corresponding to the outside of the test specimen cable,
receives a radiation in which the wavelength-dependent energy distribution
complies with the values indicated on the curve (figure 2.4.23).
Figure 2.4.23
To take account of the dispersion of the lamps and their ageing, the following
tolerances are accepted:
(i) 20% in the area of ultra-violet radiation (wavelengths below 400 nm).
(ii) 50% for the visible radiation (wavelengths above 400 nm)
This radiation may be obtained with a xenon lamp fitted with quartz filters.
(b) Test method
The samples shall follow a cycle of 5 days. During these days they shall be
subjected to the following tests:
• Exposure for one day to light radiation in a humid atmosphere, (relative
humidity ≥ 85%), at the temperature of (25 ± 2)ºC with sprinkling.
NOTE The sprinkling of demineralized water lasts three minutes per period of twenty
minutes; it is done with the aid of injectors in which the water discharge should be sufficient
to ensure the washing of all the test specimens.
---------------------- Page: 9 ----------------------
SIST HD 605 S1:1998/A2:2002
HD 605 S1:1994/A2:2001 - 8 -
• Exposure for one day in a humid atmosphere at the temperature of
(50 ± 2)ºC with thermal shocks obtained by being put into an enclosure kept
at (-25 ± 2)ºC for three one-hour periods. The hot-cold or cold-hot transfers
should be done in the shortest time possible.
The time the test specimens remain in a humid atmosphere between two
thermal shocks should be one hour or more.
• Two days exposure to light radiation in a dry atmosphere during which the
temperature is kept at (70 ± 2)ºC and the relative humidity is less than 30%.
• The fifth day, exposure for 8 hours with 0,067% in volume of sulphur
dioxide and kept at a temperature of (40 ± 3)ºC with saturating humidity.
For the last 16 hours the door of the enclosure is left open to the laboratory
environment.
During the exposures the test-pieces, similar to those defined for the tensile
test, shall be placed on supports, taking care that they are not subjected to any
tensile force.
At the end of the test, the samples shall be removed and kept protected form
direct sunlight in the laboratory atmosphere for 24 hours at least. A visual
verification shall then be carried out to ensure that there is no significant
discolouration between the aged test pieces and those not subjected to the test.
(c) Test pieces
The test requires two batches of six test-pieces; one of them being the
reference batch.
• The reference batch shall be kept at ambient temperature avoiding direct
sunlight throughout the environmental testing.
• The other batch shall be subjected to the specified 5 days cycle and then
conditioned like the reference batch for 24 hours.
After the visual for any significant discolouration the elongation at break (A.)
and tensile strength (R.) of the test-pieces from each of the batches shall be
measured in accordance with EN 60811-1-1 subclause 9.2, i.e. respectively:
• Reference batch: A and R
0 0
• Exposed batch: A and R
1 1
