# Commission Regulation (EU) 2017/2400 of 12 December 2017 implementing Regulation (EC) No 595/2009 of the European Parliament and of the Council as regards the determination of the CO2 emissions and fuel consumption of heavy-duty vehicles and amending Directive 2007/46/EC of the European Parliament and of the Council and Commission Regulation (EU) No 582/2011 (Text with EEA relevance), Division 7.3: Pass/Fail check

Extent: E+W+S+N.I.

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:
FC m-c = FC m,corr × ef + mileage × 1 − ef 15000 km [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:
C VTP = FC m-c FC sim
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:
CO 2verified = C VTP × CO 2declared
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.
