Introduction

This Annex sets out the requirements for the verification testing procedure, which is the test procedure for verifying the CO2 emissions of new heavy-duty vehicles.

The verification testing procedure consists of an on-road test to verify the CO2 emissions of new vehicles after production. It shall be carried out by the vehicle manufacturer and supervised by the approval authority that granted the licence to operate the simulation tool. In case of heavy buses the verification testing procedure shall be performed by the manufacturer of the primary vehicle.

During the verification testing procedure the torque and speed at the driven wheels, the engine speed, the fuel consumption, the pollutant emissions 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 CO2 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. To pass the verification testing procedure the CO2 emissions calculated from the measured fuel consumption shall be within the tolerances set out in point 7 compared to the CO2 emissions from the verification testing procedure simulation. Figure 1 gives a schematic picture of the verification testing procedure method. The evaluation steps as performed by the simulation tool in the verification testing procedure simulation are described in Appendix 1 of this Annex.

As part of the verification testing procedure, the correctness of the vehicle input data set from the certification of CO2 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.
