Introduction
In rope access systems, rope adjustment devices are used in combination with suitable anchor lines,
which could be a working line or a safety line, e.g. made of ropes conforming to Type A of EN 1891:1998.
Rope adjustment devices are intended to be used to link suitable sit harnesses (e.g. conforming to EN 813)
or suitable full body harnesses (e.g. conforming to EN 361) to a working line and a safety line to allow
access, egress and changes in the work position, to give support and to protect against falls.
Attention is drawn to the limitations of rope adjustment devices. Type A rope adjustment devices are for
use on safety lines to prevent a fall in the event of failure of the working line or its components. However,
in extreme circumstances, such as failure of the working line or its components during improper use of
the system, Type A rope adjustment devices may be called upon to prevent or arrest a limited fall. This is
reflected in the test requirements. Type B and C rope adjustment devices are for ascending and
descending a working line respectively, but also have a fall prevention function. The design of each type
may be incorporated into another when, in every case, they should meet the higher requirements of any
common or similar test.
In a rope access system, the worker is typically protected by a Type A rope adjustment device connected
to a safety line and a Type B or C rope adjustment device connected to a working line. The two rope
adjustment devices with their respective anchor line are all components of the protective system. It is
fundamental for the safe use of a rope access system that the worker is always connected to both anchor
lines, and that any slack in the anchor lines and connecting lanyards is avoided.
A non-exhaustive list of useful information for the rope adjustment devices described in this document is
provided in the informative Annex A.

Remove the anchor line from the water. Attach a new rope adjustment device on the anchor line and
immerse both for (10 ± 1) s in the water. Remove from the water and drain the rope adjustment device
and the anchor line in their working position for (15 ± 1) min. Subject them to a temperature of (- 4 )

°C for a minimum of 4 h.
The test shall be carried out within a temperature range of (23 ± 5) °C and shall begin within 1 min to 2
min of removal from the conditioning atmosphere.
5.3 General tests
5.3.1 Test samples
An unused rope adjustment device shall be used for these tests. The tests, except of 5.3.3 and 5.3.4, shall
be carried out on the anchor lines in accordance with 4.1.1 with a length of (3 ± 0,05) m.
5.3.2 Compatibility
5.3.2.1 Release prevention
Attach the rope adjustment device to the anchor line in accordance with the manufacturer’s instructions
and information. Check that it requires at least two consecutive manual actions to remove the rope
adjustment device from the anchor line, to ascertain that it cannot be removed accidentally in use.
The tests shall be carried out on the anchor lines in accordance with 4.1.1.
5.3.2.2 Placement
Suspend the anchor line from a suitable anchor point. Following the manufacturer’s instructions and
information, attach the rope adjustment device to the anchor line. Raise it by hand for (100 ± 20) mm and
release. Observe that the rope adjustment device stops its downward movement on the anchor line
within 300 mm. For Type A rope adjustment devices, repeat this test for all possible methods of release.
The tests shall be carried out on the anchor lines in accordance with 4.1.1.
5.3.3 Edge design
By visual and tactile means, check that the surfaces of the rope adjustment device are free from any rough
or sharp edges that can cause injury to the user.
5.3.4 Corrosion resistance
5.3.4.1 Exposure to corrosive atmosphere
Expose the rope adjustment device to the neutral salt spray test in accordance with EN ISO 9227:2022

5.3.4.2 Corrosion resistance examination
Examine the metal parts. Where necessary to gain visual access to the internal elements, rope adjustment
devices shall be dismantled. The examination shall be completed within 60 min of removal from the
corrosion chamber.
5.4 Specific tests
5.4.1 Length of connecting elements
Attach one end of the connecting element to a suitable fixture. Apply a load without shock in the form of
a mass of (10 ± 0,1) kg, or a corresponding force, to the other end of the connecting element. Maintain the
load described above for (60 ± 15) s. Within 10 s, with the load still applied, measure the connecting
element length L between the extremity load bearing points in metres to the nearest 0,01 m (see Figure 1)
and verify if the requirement of 4.3.1 is met.

5.4.2 Movement test
5.4.2.1 The tests shall be carried out with the anchor lines in accordance with 4.1.1 with a length of (3
± 0,05) m.
5.4.2.2 For Type A rope adjustment devices, check that the rope adjustment device travels freely on the
anchor line, which is loaded with (2 ± 0,01) kg, over a distance of at least 1,0 m in both directions by
pulling the connecting element by hand and by operating the rope adjustment device in accordance with
the manufacturer’s instructions and information. Repeat the test with a rope adjustment device including
the anchor line conditioned in accordance with 5.2.2 to 5.2.4. If the manufacturer claims that the rope
adjustment device is suitable for use in wet and cold conditions, repeat the test with an anchor line
conditioned in accordance with 5.2.5.
5.4.2.3 For Type B rope adjustment devices, check that the rope adjustment device fitted with a
connector can move freely on the anchor line in the upward direction by operating it in accordance with
the manufacturer’s instructions and information. Repeat the test with a rope adjustment device including
the anchor line conditioned in accordance with 5.2.2 to 5.2.4. If the manufacturer claims that the rope
adjustment device is suitable for use in wet and cold conditions, repeat the test with an anchor line
conditioned in accordance with 5.2.5.
NOTE A new sample anchor line can be used for each test.
5.4.3 Release prevention test for Type B rope adjustment devices
5.4.3.1 General
The tests shall be carried out with the anchor lines in accordance with 4.1.1.
5.4.3.2 Pushing test
Attach the anchor line to the rope adjustment device and a connector in the upper hole of the rope
adjustment device. If there is no upper hole, clamp or use any other means of attachment without
influence on the test. Connect an anchor line loop to the test apparatus as shown in Figure 2. Attach the
connector to the test apparatus and apply a force of (400 ± 10) N, at a constant rate of (100 ± 20)
mm/min. Release the force immediately.
Check that the anchor line has not become detached from the rope adjustment device.
Figure 2 — Example of pushing test
5.4.3.3 Pulling test
Attach the anchor line to the rope adjustment device and a connector to the attachment point of the rope
adjustment device. Attach both ends of the anchor line and the connector on the attachment point to the
test apparatus as shown in Figure 3. The slack on the untensioned upper strand shall be at least 100 mm
(see Figure 3). Apply a force of (2 000 ± 10) N on the lower strand using a constant rate of (100 ± 20)
mm/min. Release the force immediately.
Check that the anchor line has not become detached from the rope adjustment device.
