Conditions of the Vehicle. 3.2.1. General conditions The vehicle shall be representative of vehicles to be put on the market as specified by the manufacturer in agreement with the Technical Service to fulfil the requirements of this Regulation. Measurements shall be made without any trailer, except in the case of non- separable vehicles. In the case of HEVs/FCHVs, the test shall be carried out in the most energy efficient mode so to avoid the restart of the ICE, e.g. all audio-, entertainment-, communication- and navigation-systems shall be switched off. Before the measurements are started, the vehicle shall be brought to its normal operating conditions.
3.2.2. Battery state of charge If so equipped, propulsion batteries shall have a state-of-charge sufficiently high to enable all key functionalities according to the manufacturer's specifications. Propulsion batteries shall be within their component- temperature window to enable all key functionalities that could reduce vehicle sound emissions. Any other type of rechargeable energy storage system shall be ready to operate during the test.
3.2.3. Multi-mode operation If the vehicle is equipped with multiple driver selectable operating modes, the mode which provides the lowest sound emission during the test conditions of paragraph 3.3. shall be selected. When the vehicle provides multiple operating modes that are automatically selected by the vehicle, it is the responsibility of the manufacturer to determine the correct manner of testing to achieve the minimum sound emission. In cases where it is not possible to determine the vehicle operating mode providing the lowest sound emission, all modes shall be tested and the mode giving the lowest test result shall be used to report the vehicle sound emission in accordance with this Regulation.
3.2.4. Test mass of vehicle Measurements shall be made on vehicles at mass in running order with an allowable tolerance of 15 per cent.
3.2.5. Tyre selection and condition The tyres fitted to the vehicle during testing are selected by the vehicle manufacturer, and shall correspond to one of the tyre sizes and types designated for the vehicle by the vehicle manufacturer. The tyres shall be inflated to the pressure recommended by the vehicle manufacturer for the test mass of the vehicle.

Measurements shall be made without any trailer, except in the case of non-separable vehicles. In the case of HEVs/FCHVs, the test shall be carried out in the most energy efficient mode so to avoid the restart of the ICE, e.g. all audio-, entertainment-, communication- and navigation-systems shall be switched off. Before the measurements are started, the vehicle shall be brought to its normal operating conditions.
