Target conditions. The sound emission shall be measured in each valid gear ratio at the four test points as specified below. The first test point P1 is defined by using an entry speed vAA of 20 km/h. If a stable acceleration condition cannot be achieved, the speed shall be increased in steps of 5 km/h until a stable acceleration is reached. The fourth test point P4 is defined by the maximum vehicle speed at BB' in that gear ratio within the boundary conditions according to paragraph 2.3. The other two test points are defined by the following formula: Test Point Pj: vBB_j = vBB_1 + ((j - 1) / 3) * (vBB_4 - vBB_1) for j = 2 and 3 Where: vBB_1 = vehicle speed at BB' of test point P1 vBB_4 = vehicle speed at BB' of test point P4 Tolerance for vBB_j: ±3 km/h For all test points the boundary conditions as specified in paragraph 2.3. shall be met.
