BS/EN 1496-2017 pdf download.Personal fall protection equipment – Rescue lifting devices.
Withdraw the line by at least 1 000 mm from the rescue lifting device and attach test mass A to the end termination in the line.
Where relevant, engage the rescue mechanism in accordance with the information supplied by the manufacturer.
Hold the test mass by means of the controlling feature.
Apply a force of a maximum of 250 N to the handle of the controlling feature in such a way that it operates as intended.
Check whether the force lifts the test mass.
5.5 Dynamic performance test for class B rescue lifting devices
5.5.1 Apparatus
The test apparatus shall conform to EN 364:1992,4.4,4.5 and 4.6.
5.5.2 Procedure
Attach the rescue lifting device in the intended position of the rescue lifting device to the anchor point
of the test apparatus.
If the rescue lifting device is intended to be fitted to a tripod or similar anchor device, then test the whole unit.
Withdraw the line by (4ooo°) mm from the rescue lifting device and attach test mass A to the end termination of the line, incorporating a force measurement instrument to measure the braking force.
Raise the test mass by (6OO) mm, with a maximum horizontal distance of 300 mm from the centre line (see Figure 1). Hold the test mass by the quick release device. In the case of rescue lifting devices with an automatic retraction function, prevent the line from retracting by a clamp.
Where relevant, engage the rescue mechanism in accordance with the information supplied by the manufacturer.
Release the test mass without initial velocity.
Measure the braking force.
Repeat the test for every intended orientation and/or position of the rescue lifting device. Where the manufacturer gives a range of orientations of use for the rescue lifting device, carry out a test at each extreme orientation and one centrally between the two, using an appropriate anchor point.
A new test sample may be used for each test.
5.7.2 Test procedure
Expose the rescue lifting device (including the line and any fittings) to the neutral salt spray test in accordance with EN ISO 9227 for (24’) h. Dry for (6o) mm at (20 ± 2) °C. Then repeat the
procedure, so that the rescue lifting device is subjected In total to (24) h exposure and (0’) mm drying plus another (24) h exposure and (60) mm drying.
Examine the specimen within 90 s after drying and check for signs of corrosion. Where necessary to gain visual access to internal parts, dismantle the rescue lifting device.
NOTE If the rescue lifting device is integrated into an anchor device In accordance with EN 795. it is sufficient to test only the rescue lifting device and not the anchor device.
5.8 Function test
5.8.1 Test procedure for rescue lifting devices class A
5.8.1.1 Carry out the test at the maximum lifting distance as given in the information supplied by the manufacturer.
5.8.1.2 Attach the rescue lifting device to an appropriate anchor point.
Fully extract the line to correspond to the working length of the rescue lifting device. Where relevant, engage the rescue mechanism in accordance with the information supplied by the manufacturer.
5.8.1.3 Attach test mass B to the end of the extracted line.
By means of the controlling feature, lift the test mass until there is (1 000 ± 100) mm of line remaining outside the rescue lifting device.
Release the controlling feature and measure the arrest distance.
Where the manufacturer permits different positions or orientations of the rescue lifting device, repeat the procedure at each orientation / position, by lifting the test mass until there is (1 000 ± 100) mm of line remaining below the point at which the line commences to hang downwards (e.g. the top pulley of a tripod). Where the manufacturer gives a range of orientations of use for the rescue lifting device, carry out a test at each extreme orientation and one centrally between the two.
A new test sample may be used for each test.
5.8.1.4 Repeat the procedure specified In 5.8.1.2 and 5.8.1.3, replacing test mass B with test mass C.BS/EN 1496-2017 pdf download.
