Division 1.1

The noise made by the vehicle type submitted for F1GB type-approval shall be measured by the two methods described in this Annex for the vehicle in motion and for the vehicle when stationary. In the case of a hybrid electric vehicle where an internal combustion engine cannot operate when the vehicle is stationary, the emitted noise shall only be measured in motion.

Vehicles having a technically permissible maximum laden mass exceeding 2800 kg shall be subjected to an additional measurement of the compressed air noise with the vehicle stationary in accordance with the specifications of Annex V, if the corresponding brake equipment is part of the vehicle.
