5 Test methods
5.1 Test samples
A test sample with a length of:
— 40 m for single and half ropes,
— 80 m or 2 × 40 m for twin rope;
shall be available for the tests.
Carry out the tests in accordance with 5.3 on an unused test sample.
Carry out the tests in accordance with 5.4 on two unused test samples with a length of (2 250 ± 10) mm.
Carry out the test in accordance with 5.5 on two unused test samples with a length of at least 1 500 mm.
Carry out the tests in accordance with 5.6 on three unused test samples with a minimum length of 5 m
for single and half ropes, and 10 m for twin ropes, cut out of the available test sample.
5.2 Conditioning and test conditions
Dry the test samples for at least 24 h in an atmosphere of (50 ± 5) °C and less than 20 % relative
humidity. Then condition these test samples in an atmosphere of (23 ± 2) °C and (50 ± 2) % relative
humidity for at least 72 h. Then start testing these samples at a temperature of (23 ± 5) °C within 10
min.
5.3 Construction, diameter, and mass per unit length
5.3.1 Procedure
Clamp the test sample at one end.
1)
Load the test sample without shock with a mass of:
— (10 ± 0,1) kg for single ropes,
— (6 ± 0,1) kg for half ropes,
— (5 ± 0,1) kg for twin ropes
at a distance of at least 1 200 mm from the clamp.
After applying the load for 60 s mark within the next 10 s a reference length of (1 000 ± 1) mm on the
test sample. The distance of the marking from the clamp or attachment for the test sample shall be at
least 50 mm.
Within a further 3 min measure the diameter in two directions around the diameter starting at points
90° apart at each of three levels approximately 100 mm apart. If the rope cross section is not circular,
the maximum and minimum diameter are to be determined in each section. The length of the contact
areas of the measuring instrument shall be (50 ± 1) mm. The rope cross-sectional area shall not be
subject to any compression during the measurement.
Then cut out the marked portion of the test sample and determine the mass to the nearest 0,1 g.
1)
The mass can be introduced by a corresponding force.

5.3.2 Expression of results
Express the diameter as the arithmetic mean of the six measurements to the nearest 0,1 mm.
Express the mass per unit length in ktex or g/m to the nearest 1 g.
5.4 Sheath slippage
5.4.1 Principle
The rope is drawn through the apparatus illustrated in Figure 4, where the movement is restricted by
radial forces. The resulting frictional force on the sheath causes slippage of the sheath relative to the
core. The extent of this slippage is measured.

5.4.2 Preparation of the test samples
Fuse one end of the sheath and core of each test sample together. Before cutting the other end of each
test sample to size, apply a short length of adhesive tape around the rope, where it is to be cut, at right
angles to the axis of the rope. The adhesive tape shall be at least 12 mm wide before cutting, and the
angle of wrap around the rope, Θ, shall be 150° ≤ Θ ≤ 180°. After affixing the adhesive tape, cut the

sample to a length of (2 250 ± 10) mm with a sharp knife, within the width of the tape, at right angles to
the axis of the rope (see Figure 5) such that the adhesive tape remaining on the test sample has a width
of (10 ± 5) mm. The characteristics of the adhesive tape and the method of application should be such
as to reduce the extent to which the cut end of the sheath unravels during the test, whilst not interfering
with the slippage taking place between the core and the sheath of the rope sample.

5.4.3 Apparatus
The apparatus shall consist of a frame made out of four steel plates each 10 mm thick, kept equal
distances apart by three spacers. These spacers shall have rectangular slots in which three inserted
steel plates are able to slide in a radial direction. The spacers shall be arranged in such a way as to allow
each of the three inserted plates to slide at an angle of 120° (see Figure 5).
Each of the seven plates shall have an opening with a diameter of 12 mm; their internal surfaces shall be
semitoroidal and have a radius of 5 mm. The polished surfaces of the semi-torus shall show:
— an arithmetical mean deviation of the profile of R = 0,4 µm and

The moving plates shall have a locked position in which the openings in the fixed plates and the
openings in the moving plates all lie in line along a central axis. When not in their locked position each
of the moving plates shall apply a radial force of (50 ± 0,5) N to the test sample in the direction in which
the plate moves. The test apparatus shall be rigidly mounted with its axis horizontal. Means shall be

5.4.4.2 Introduce the fused end of the test sample into the apparatus and pull to a length of
(200 ± 10) mm through the test apparatus (see Figure 7). Ensure that the remainder of the test sample
is not subjected to any load and lies in a horizontal position in a straight line.

rigidity, the bar shall be as short as reasonably practicable whilst allowing two twin ropes or one single
rope each to be wound around its circumference three times. There shall be two clamps fixed rigidly in
relation to the bollard in accordance with the dimensions in Figures 10 and 11, and capable of fixing the
free end(s) of the rope(s).
