The required overall measurement accuracy shall be as follows:
(a)Vehicle speed accuracy: ± 0,2 km/h with a measurement frequency of at least 10 Hz;
(b)Time: min. accuracy: ± 10 ms; min. precision and resolution:10 ms;
(c)Wheel torque accuracy: ± 6 Nm or ± 0,5 per cent of the maximum measured total torque, whichever is greater, for the whole vehicle, with a measurement frequency of at least 10 Hz;
(d)Wind speed accuracy: ± 0,3 m/s, with a measurement frequency of at least 1 Hz;
(e)Wind direction accuracy: ± 3°, with a measurement frequency of at least 1 Hz;
(f)Atmospheric temperature accuracy: ± 1 °C, with a measurement frequency of at least 0,1 Hz;
(g)Atmospheric pressure accuracy: ± 0,3 kPa, with a measurement frequency of at least 0,1 Hz;
(h)Vehicle mass measured on the same weighing scale before and after the test: ± 10 kg (± 20 kg for vehicles > 4 000 kg);
(i)Tyre pressure accuracy: ± 5 kPa;
(j)Wheel rotational speed accuracy: ± 0,05 s– 1 or 1 per cent, whichever is greater.
