10.1.                                DEFINITIONS

         10.1.0. Refer to Vehicle Standard (Australian Design Rule Definitions and Vehicle Categories) 2005.

10.1.1.                          'Steering Column' - a structural housing that surrounds a 'Steering Shaft'.
10.1.2.                          'Steering Shaft' - a component that transmits steering torque from the steering wheel to the steering gear.

10.2.                                REQUIREMENTS

10.2.1.                          The 'Steering Column' assembly including the steering device which is actuated by the driver shall be so constructed that when it is impacted by a body block in accordance with SAE Recommended Practice J944 'Steering Wheel Assembly Laboratory Test Procedure, December 1965 or J944a - "Steering Control System Passenger Car - Laboratory Test Procedure', November 1968 or other 'Approved' procedure, the body block, moving at a speed of not less than 6.7 m/s in a direction equivalent to a horizontal longitudinal direction relative to the top of the 'Steering Column' in the vehicle, shall be brought to rest in such a manner that at no time shall the load exerted on the body block by the 'Steering Column' assembly including the steering device which is actuated by the driver exceed 11.1 kN.

10.2.2.                          The upper end of the 'Steering Column' and the 'Steering Shaft' shall not be displaced horizontally 'Rearward' parallel to the longitudinal axis of the vehicle relative to an undisturbed point on the vehicle more than 127 mm, determined by dynamic measurement, in a barrier collision test at 48 km/h minimum conducted in accordance with SAE Recommended Practice J850, 'Barrier Collision Tests', February 1963 or other 'Approved' practice.

10.2.3.                          When conducting the barrier collision test, a dummy may be used providing the dummy does not contact the 'Steering Column' assembly or steering wheel during the test

10.2.4.                          The speed at the time of impact shall be at least 48 km/h.  If the speed measured is greater than the nominal speed of 48 km/h the measured displacement of the upper end of the 'Steering Column' and the 'Steering Shaft' may be reduced to a value appropriate to the nominal speed by multiplying it by the square of the ratio between the nominal speed and either the measured speed or 53.1 km/h, whichever is the lesser.
