T0 - standard ambient absolute temperature, T0=293 K (20 ℃). The outdoor test ambient temperature shall be between 0℃ and 40℃. The indoor test ambient temperature shall be between 23℃ and 5℃. The atmospheric pressure shall be between 91 kpa and 104 kpa. 4.2.2 Air velocity For Category M1 vehicles and Category N1 vehicles with the maximum designed gross mass less than 2 t, the air velocity shall be measured at a position 0.7 m above the road surface. For other vehicles, the air velocity shall be measured at a position 1.6 m above the road surface. The average air velocity shall not exceed 3 m/s and the maximum air velocity shall not exceed 5 m/s. 4.2.3 Relative humidity The relative humidity shall be less than 95%. 4.3 Measurement parameter, unit and accuracy Table 1 specifies the measurement parameters, unit and accuracy.
