4 Safety requirements
4.1 Construction
Dynamic ropes in accordance with this European Standard shall be made in a kernmantel construction.
Diameter and mass per unit length are relevant characteristics. See test method in 5.3.
If the properties of the rope change along its length, for example: diameter, strength, markings, samples
from each section shall be submitted for testing. The information to be supplied shall all correspond to
the lowest performance section of the rope.
4.2 Sheath slippage
When tested in accordance with 5.4, the sheath slippage in a longitudinal direction relative to the core
(in positive or negative direction) shall not exceed 1 % (20 mm) (see Figure 3).

b negative sheath slippage ≤ 20 mm

4.3 Static elongation
When tested in accordance with 5.5, the static elongation shall not exceed:
— 10 % in single ropes (single strand of rope);
— 12 % in half ropes (single strand of rope);
— 10 % in twin ropes (double strand of rope).
4.4 Dynamic Elongation
When tested in accordance with 5.6, the dynamic elongation shall not exceed 40 % during the first drop
for each test sample.
4.5 Peak force during fall arrest, number of drops
4.5.1 Peak force in the rope
When tested in accordance with 5.6, the peak force in the rope, during the first drop, for each test
sample, shall not exceed:
— 12 kN in single ropes (single strand of rope);
— 8 kN in half ropes (single strand of rope);
— 12 kN in twin ropes (double strand of rope).
4.5.2 Number of drops
When tested in accordance with 5.6, each rope sample shall withstand at least 5, for twin ropes at least
12, consecutive drop tests without breaking.
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.
Check that the construction of the rope is a kernmantel construction.
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.
