F1 Inserted by Commission Regulation (EU) 2019/318 of 19 February 2019 amending Regulation (EU) 2017/2400 and Directive 2007/46/EC of the European Parliament and of the Council as regards the determination of the CO2 emissions and fuel consumption of heavy-duty vehicles (Text with EEA relevance).

1. Introduction U.K.

This Annex sets out the requirements for the verification testing procedure which is the test procedure for verifying the CO ₂ emissions of new heavy-duty vehicles.

The verification testing procedure consists of an on-road test to verify the CO ₂ emissions of new vehicles after production. It shall be carried out by the vehicle manufacturer and verified by the approval authority that granted the licence to operate the simulation tool.

During the verification testing procedure the torque and speed at the driven wheels, the engine speed, the fuel consumption, the engaged gear of the vehicle and the other relevant parameters listed in point 6.1.6 shall be measured. The measured data shall be used as input to the simulation tool, which uses the vehicle-related input data and the input information from the determination of the CO ₂ emissions and fuel consumption of the vehicle. For the verification testing procedure simulation, the instantaneously measured wheel torque and the rotational speed of the wheels as well as the engine speed shall be used as input, as described in Figure 1 instead of the vehicle speed, in accordance with point 6.1.6. The fan power during the verification testing procedure shall be calculated in accordance with the measured fan speed. The measured fuel consumption shall be within the tolerances set out in point 7 and compared to the fuel consumption simulated with the verification data set to pass the verification testing procedure.

As part of the verification testing procedure, the correctness of the vehicle input data set from the certification of CO ₂ emissions and fuel consumption related properties of the components, separate technical units and systems shall also be reviewed to check the data and the data handling process. The correctness of the input data relating to components, separate technical units and systems relevant for air drag and for rolling resistance of the vehicle shall be verified in accordance with point 6.1.1.
