The pendulum is supported so that the rigid bar is at an angle of 30 ± 2 to the vertical and then it falls freely and strikes the back of the wheelchair. For wheelchairs where the backrest is mounted on two supporting members the test is repeated twice with the pendulum repositioned so that it strikes the central line of each backrest support 20 mm below the top of the backrest. For wheelchairs where the backrest is mounted on a single central support the test is repeated with the pendulum positioned to strike the backrest points located 0.4 times the backrest max. age 5 of 8 roject Manager: hone: + 49 511 9663-822
rüfpunkt Anforderung + rüfung width from each side of its centreline. Castors The castor is set up so that it is to be tested aligned at 45 ± 5 to the longitudinal axis of the wheelchair. The plane of the pendulum s swing has to be in the plane of the castor wheel ± 2. The pendulum is located so that it is hanging vertically with its centre of percussion of one side face on the same horizontal line as the castor hub ± 5 and touching the wheel rim. The angle of swing is calculated from following equation: M 1 d M Cos w 377 with: = angle of swing in degrees M = max. dummy mass in kg d M = wheelchair mass in kg w M d = 140 kg M w = 25 kg = 56 The pendulum is raised so that its longitudinal axis is at + 3 to the vertical and then it is released so that it strikes the castor wheel. If the manufacturer claims that the wheelchair exceeds the min. requirement the angle claimed by the manufacturer with a tolerance of + 3 is used. The test is repeated on all other castors of the wheelchair. Footrests If the wheelchair is fitted with two separate footrests, both tests are performed on one footrest. If the wheelchair is fitted with a single footrest, both tests are performed on the same side of that footrest. a) Lateral impact The footrest test pendulum is suspended so that its centre or percussion touches that part of the footrest which is nearest to the test plane and furthest from the wheelchair longitudinal centreline, its plane of swing in normal to the wheelchair longitudinal centreline ± 2 and the longitudinal axis of the pendulum is vertical. The pendulum is raised so that its longitudinal axis is at + 3 to the vertical and released so age 6 of 8 roject Manager: hone: + 49 511 9663-822

If the manufacturer claims that the wheelchair exceeds the above requirement the angle claimed by the manufacturer with a tolerance of + 3 is used. If the footrest has moved from its setting but is undamaged, reset it to its initial position. b) Longitudinal impact The footrest pendulum is suspended so that its centre of percussion touches that part of the footrest which is furthest forward and furthest from the wheelchair longitudinal centreline; its plane of swing is parallel to the wheelchair longitudinal centreline; the longitudinal axis of the pendulum is vertical. 13.3.5 Fatigue strength test Escalator test cycles: 150 000 steps Drop test The lifting height shall be set so that the vertical component of the lift of the combined centre of gravity of the whole assembly of stair-climbing device plus surrogate wheelchair (if used) and dummy is 25 mm ± 3 mm. cycles: 1 000 drops 13.3.6 Durability test With the stair-climbing device standing horizontally in front of the standard test stairs following the anufactu rer s instructions, drive the stair- climbing device up the stairs onto the landing platform. Immediately position the stair-climbing device for descending the stairs following the manufacturer s instructions. Drive the stairclimbing device down the stairs so that the whole stair-climbing device is on the horizontal plane. The tests were performed at the test facility in the manufacturer s location. The results are documented in the test reports no 41000007 and 410000015.
