5.1 Test samples
A minimum of two new autobelay device samples shall be provided: one for the purposes of the tests
specified in 5.2, 5.3, 5.5 and 5.8 and one for the purposes of the tests specified in 5.4, 5.6 and 5.7.
NOTE Depending on the configuration, the claim in the product instructions and information for the intended
use, the material of the retractable safety line and the class of the device, more than two samples or additional
samples of components can be required.
5.2 Examination
Confirm by reference to appropriate documentation accompanying the autobelay device and by
measurement and by normal or corrected vision and/or tactile examination of the autobelay device that
it conforms to the relevant part of 4.1.1, 4.1.2, 4.1.2.2, 4.1.2.3, 4.1.2.4, 4.1.2.5, 4.1.2.6, 4.1.3 and relevant
part of 4.1.4. If necessary to examine internal parts, dismantle the autobelay device.
5.3 Retraction system tests
5.3.1 Retraction system test
Check the retraction system ability using the method described in the product instructions and
information. Measure and record the time for evaluation.
5.3.2 Retraction system malfunction
The autobelay device retraction system for the retractable safety line is manipulated in accordance with
the product instructions and information in a way that simulates neutralization of a retraction spring
(other failures shall be evaluated if no spring system used).
The manipulated autobelay device is attached by its anchor point to the test apparatus, in accordance
with the product instructions and information, at maximum mounting height (±100) mm. Suspend with
an anchor point within 300 mm maximum horizontal distance from the anchor point used for the
autobelay device a test mass equivalent to the maximum rated load in accordance with manufacturer’s
 +100
instructions and information, at a height mm from the ground (see Figure 3).

Attach the connecting element to a test mass equivalent to the maximum rated load, and then verify if the
retractable safety line comes out of the device without additional pull (only the retractable safety line
weight pulls on it).

Afterwards, raise the test mass with the same test apparatus by mm. Hold the test mass by the

quick release device. Release the test mass without initial velocity (see Figure 3). Record the landing
speed. Verify that the requirements in 4.2.2 are met.
Alternatively, the retractable safety line may be shortened by a knot if testing height is not sufficient.

5.3.3 Twisting
The autobelay device is attached by its anchor point to the anchor point of a crane or winch and not
allowed to rotate, in accordance with the product instructions and information, at maximum mounting
height. The retractable safety line, pulled out of the device at its maximum, is twisted with 10 turns in one
direction. While holding the connecting element stationary at its intended user load bearing point, the
autobelay device should be lowered down completely via crane or winch from maximum height to the
connecting element, allowing the retractable safety line to retract, with a retraction speed of minimum
0,5 m/s , but not faster than retraction speed of tested autobelay device.
The retractable safety line shall retract fully and continuously into autobelay device during the lowering
of the autobelay device. All 10 twisted turns in the retractable safety line shall then be untwisted. The test
shall be repeated twisting the retractable safety line 10 turns in the opposite direction.
5.3.4 Retraction speed
Fully extract the vertically free hanging retractable safety line with connecting element from an autobelay
device. Release and calculate average retraction speed for fully retracted retractable safety line with an
uncertainty of measurement of (±0,2) m/s.
The autobelay device can be damaged by letting out the retractable safety line without load on it. If that
occurs in that test, use another test sample for further tests.
The retraction speed increasing or decreasing slightly over the retraction distance is acceptable.
5.4 Dynamic strength tests
5.4.1 Impact force test of autobelay device
The test apparatus shall conform to 4.4.1, 4.4.2 and 4.6 of EN 364:1992. The test masses shall have the
same diameter than those according to EN 364:1992, 4.5.
Attach a new autobelay device by its anchor point to the anchor point of the test apparatus, in accordance
with the product instructions and information, in minimum mounting height. Attach a load cell between
the autobelay device anchor point and the anchor point of the test apparatus. Raise the test mass of
maximum rated load, which is fixed on the connecting element of the retractable safety line

Hold the test mass by the quick release device. Release the test mass without initial velocity.
Measure and record the braking force and the descent speed measured at (1 000 ± 50) mm above the
ground.
Check that the autobelay device does not release the test mass and does not show any signs of breaking
or tearing.
