Division 5.1 TorqueF1

The direct torque at all driven axles shall be measured with one of the following measurement systems fulfilling the requirements listed in Table 2:

1. (a)

   hub torque meter;

2. (b)

   rim torque meter;

3. (c)

   half-shaft torque meter.

The calibrated range shall be at least 10 000 Nm; the measurement range shall cover the entire range of torque occurring during the verification testing procedure of the tested vehicle.

The drift shall be measured during the verification test described in point 6 by zeroing the torque measurement system in accordance with point 6.1.5 after the pre-conditioning phase by lifting the axle and measuring the torque at lifted axle directly after the verification test again.

For a valid test result a maximum drift of the torque measurement system over the verification testing procedure of 150 Nm (sum of both wheels) shall be proven.
