18 Access Rail System – R27
1.2 The surveyor will have to approve the individual test regime and be satisfied it was done correctly. In practice
this normally means overseeing the test.
1.3 For new builds or for identical constructions, the proof test can be done on representative sample pieces.
These should be long enough to hold a pair of cars in normal configuration plus the end stops. In practice,
500 mm would be suitable.
1.4 This can be applied to installations if the construction is identical and as long it is properly documented.
1.5 In the case of retro-fits where the construction is not necessarily known (due to modifications, corrosion
or aging), the proof testing will have to be done in situ.
1.6 If done in place, then we recommend testing in highest risk locations such as where personnel gain access
to the system or at the ends of the rails.
1.7 Subject to surveyor approval, the proof test procedure would be:
Note: This is a static test. There is no drop load. The car is not expected to move under these conditions
i. Attach a water bag to a single car.
ii. Fill to achieve a load of 1200 kg.
iii. Hold for 3 minutes without deformation – paying particular to rail/fastener stability.
iv. Drain/unload water bag, move and repeat in two further locations (or sample pieces).
v. The system should remain functional.
2. InSTALLATIOn TESTIng:
2.1 This test objective is to ensure that the system has been installed correctly in practice and remains sound as it ages.
2.2 We recommend that each rail is tested in at least 3 locations, typically at both ends and at any rail joint or in
the middle.
2.3 Again subject to surveyor approval, each rail should be tested on installation as per:
i. Attach a water bag to a single car.
ii. Fill to achieve a load of 600 kg.
iii. Test for 15 seconds per location.
iv. Repeat as necessary for each separate rail.
2.4 Normal safety equipment operations requires testing post-installation and then 6 monthly routine inspection with
12 monthly testing.
2.5 Further testing and inspection of the ARS should be incorporated into standard operating practices and into the
safety records.
3.0 Documentation to be supplied after installation:
i. The installation documentation provides evidence to the end uses and that the installation has been carried
out properly.
ii. The documentation should be handed over to the user and kept on hand for subsequent examinations of
the device.
