Division 7.3 Pass/Fail checkF1

The vehicle shall pass the verification test if the ratio of corrected measured fuel consumption to simulated fuel consumption is below the tolerances set out in Table 5.

In the case of a shorter run-in phase than 15 000  km the influence on the fuel efficiency of the vehicle may be corrected with the following evolution coefficient:

${\mathrm{FC}}_{\mathrm{m-c}}={\mathrm{FC}}_{\mathrm{m,corr}}\times \left(\mathrm{ef}+\mathrm{mileage}\times \frac{1-\mathrm{ef}}{15000\mathrm{km}}\right)\mathrm{[g/kWh]}$

where:

FC _m-c

Fuel consumption measured and corrected of a shorter run-in phase

mileage

run-in distance [km]

ef

Evolution coefficient of 0,98

For vehicle odometer reading above 15 000  km, no correction shall be applied.

The ratio of measured and simulated fuel consumption for the total verification test relevant trip shall be calculated as verification test ratio in accordance with the following equation:

Where:

C _VTP

Ratio of fuel consumption measured and simulated in the verification testing procedure

For a comparison with the declared CO ₂ emissions of the vehicle in accordance with Article 9, the verified CO ₂ emissions of the vehicle are determined as follows:

where:

CO _2verified

verified CO ₂ emissions of the vehicle in [g/t-km]

CO _2declared

declared CO ₂ emissions of the vehicle in [g/t-km]

If a first vehicle fails the tolerances for C _VTP , two more tests may be performed on the same vehicle or two more similar vehicles may be tested on request of the vehicle manufacturer. For the evaluation of the pass criterion set out in Table 5, the averages of the verification testing procedure ratio from the up to three tests shall be used. If the pass criterion is not reached, the vehicle fails the verification testing procedure.
