Point detail

For all states of load of the vehicle, the adhesion utilization curve of the rear axle shall not be situated above that for the front axle for all braking rates between 0.15 and 0.30. This condition is also considered satisfied if, for braking rates between 0.15 and 0.30, the adhesion utilization curves for each axle are situated between two lines parallel to the line of ideal adhesion utilization given by the equations k = z + 0.08 and k = z - 0.08 as shown in diagram 1B of this annex and the adhesion utilization curve for the rear axle for braking rates z ≥ 0.3 complies with the relation
