Appendix 6
United Kingdom
Conformity of the certified CO2 emissions and fuel consumption related properties
1.
The conformity of the certified CO2 emissions and fuel consumption related properties shall be verified by constant speed tests as laid down in section 3 of the main part of this Annex. For conformity of the certified CO2 emissions and fuel consumption related properties the following additional provisions apply:
- i..
The ambient temperature of the constant speed test shall be within a range of ± 5 °C to the value from the certification measurement. This criterion is verified based on the average temperature from the first low speed tests as calculated by the air drag pre-processing tool.
- ii..
The high speed test shall be performed in a vehicle speed range within ± 2 km/h to the value from the certification measurement.
All conformity of the certified CO2 emissions and fuel consumption related properties tests shall be supervised by the approval authority.
2.
A vehicle fails the conformity of the certified CO2 emissions and fuel consumption related properties test if the measured Cd Acr (0) value is higher than the Cd · Adeclared value declared for the parent vehicle plus 7,5 % tolerance margin. If a first test fails, up to two additional tests at different days with the same vehicle may be performed. F1Where the measured C d A cr (0) value of all performed tests is higher than the C d ·A declared value declared for the parent vehicle plus 7,5 % tolerance margin, Article 23 of this Regulation shall apply.
F2For calculation of C d A cr (0) value the air drag pre-processing tool version of the parent air drag in accordance with Attachment 1 of Appendix 2 to this Annex shall be used.
3.
The number of vehicles to be tested for conformity with the certified CO2 emissions and fuel consumption related properties per year of production shall be determined based on Table 17.
| Table 17 | |
| Number of vehicles to be tested for conformity with the certified CO2 emissions and fuel consumption related properties per year of production | |
| Number of CoP tested vehicles | Number of CoP relevant vehicles produced the year before |
|---|---|
| 2 | ≤ 25 000 |
| 3 | ≤ 50 000 |
| 4 | ≤ 75 000 |
| 5 | ≤ 100 000 |
| 6 | 100 001 and more |
For the purpose of establishing the production numbers, only air drag data which fall under the requirements of this Regulation and which did not get standard air drag values according to Appendix 8 of this Annex shall be considered.
4.
For the selection of vehicles for conformity of the certified CO2 emissions and fuel consumption related properties testing the following provisions apply:
- 4.1.
Only vehicles from the production line shall be tested.
- 4.2.
Only vehicles which fulfil the provisions for constant speed testing as laid down in section 3.3 of the main part of this Annex shall be selected.
- 4.3.
Tires are considered part of the measurement equipment and can be selected by the manufacturer.
- 4.4.
Vehicles in families where the air drag value has been determined via transfer from other vehicles according to Appendix 5 point 5 are not subject to conformity of the certified CO2 emissions and fuel consumption related properties testing.
- 4.5.
Vehicles which use standard values for air drag according to Appendix 8 are not subject to conformity of the certified CO2 emissions and fuel consumption related properties testing.
- 4.6.
The first two vehicles per manufacturer to be tested for conformity with the certified CO2 emissions and fuel consumption related properties tested shall be selected from the two biggest families in terms of vehicle production. Additional vehicles shall be selected by the approval authority.
5.
After a vehicle was selected for conformity of the certified CO2 emissions and fuel consumption related properties the manufacturer has to verify the conformity of the certified CO2 emissions and fuel consumption related properties within a time period of 12 month. The manufacturer may request the approval authority for an extension of that period for up to 6 months if he can prove that the verification was not possible within the required period due to weather conditions.
