It also includes any storage reservoirs for the operating medium and the return lines, but not the vehicle's engine (except for the purposes of item 4.1.3) or its drive to the energy source; 1.3.4.1. Energy source means that part of the energy supply which provides the energy in the required form e.g. hydraulic pump, air compressor; 1.3.4.2. Energy reservoir means that part of the energy supply in which the energy provided by the energy source is stored; 1.3.4.3. Storage reservoir means that part of the energy supply in which the operating medium is stored at or near to the atmospheric pressure. 1.4. Steering parameters 1.4.1. Steerin ...[+++]g control effort means the force applied to the steering control in order to steer the vehicle; 1.4.2. Steering time means the period of time from the beginning of the movement of the steering control to the moment at which the steered wheels have reached a specific steering angle; 1.4.3. Steering angle means the angle between the projection of a longitudinal axis of the vehicle and the line of intersection of the wheelplane (being the central plane of the tyre, normal to the spin axis of the wheel) and the road surface; 1.4.4. Steering forces mean all the forces operating in the steering transmission; 1.4.5 Mean steering ratio means the ratio of the angular displacement of the steering control to the mean of the swept steering angle of the steered wheels for a full lock-to-lock turn; 1.4.6. Turning circle means the circle within which are located the projections onto the ground plane of all the points of the vehicle, excluding the external mirrors and the front direction indicators, when the vehicle is driven in a circle; 1.4.7. Nominal radius of steering control means in the case of a steering wheel the shortest dimension from its centre of rotation to the outer edge of the rim. In the case of any other form of control, it means the distance between its centre of rotation and the point at which the steering effort is applied. ...

1. Samples shall be taken within the individual worker's breathing zone: i.e. within a hemisphere of 300 mm radius extending in front of the face and measured from the mid-point of a line joining the ears.

The hand brake control when in the released position and the gear lever when in any forward gear position, except when placed in the zones defined in points 2.3.1 and 2.3.2 and zones below the horizontal plane passing through the H point of the front seats, shall have a surface area of at least 6 75 cm2 measured at a cross-section normal to the longitudinal horizontal direction up to a distance of 6 75 mm from the furthest projecting ...[+++]part, the radius of curvature being not less than 3 72 mm.
