Paragraph 4 Testing of restraint system anchorages

The tests must be conducted on a vehicle or a representative section of a vehicle structure including any vehicle fittings that are likely to contribute to the strength or rigidity of the structure,

The forces specified in paragraph 5 below must be applied by means of a surrogate wheelchair of adequate strength as defined in ISO 10542, or equivalent, with attachment points for the front and rear tie-downs and reproducing the geometry of the wheelchair tie-down system,

The forces specified in paragraph 6 below must be applied by means of a traction device specified in paragraph 5.3.4 of Annex I to Directive 76/115/EEC as amended by Directive 96/38/EC and supported on the surrogate wheelchair defined in (b) above;

The forces in sub-paragraphs (b) and (c) above must be applied simultaneously in the forward direction at an angle of 10° ± 5° above the horizontal plane. The force in (b) must be applied at a height of not less than 200 mm and not more than 300 mm measured vertically above the floor of the wheelchair space;

The force in paragraph 5(b) must be applied in the rearward direction at an angle of 10° ± 5° above the horizontal plane at a height of not less than 200 mm and not more than 300 mm measured vertically above the floor of the wheelchair space;

All forces must be applied as rapidly as possible through the central vertical axis of the wheelchair and wheelchair space;

All forces must be maintained for a period of not less than 0.2 seconds.
