Deceleration method Clause Samples

Deceleration method. The deceleration method follows the procedure below: (a) Remove the tyre from the test surface while running at a speed greater than test speed; (b) Record the deceleration of the test drum D0/ t and that of the unloaded tyre T0/ t or record the deceleration of the test drum jD0 and that of the unloaded tyre jT0 in exact or approximate form in accordance with paragraph 3.5. above. The speed range for measurement includes the test speed and does not exceed 10 km/h above and 10 km/h below the test speed.
