Division 6.1.4 Set up of the test vehicle for the fuel consumption measurementF1

Tractors of the vehicle groups defined in Table 1 of Annex I shall be tested with any type of semitrailer, providing the loading defined below can be applied.

Rigid lorries of the vehicle groups defined in Table 1 of Annex I shall be tested with trailer, if a trailer connection is mounted. Any body type or other device to carry the loading set out below can be applied.

The bodies of the vehicles may differ from the standard bodies set out in Table 1 of Annex I for the certification of CO ₂ emissions and fuel consumption related properties of component, separate technical units or systems.

The vehicle payload shall be at minimum to a mass leading to a total test weight of 90 % of the maximum gross combined weight or gross vehicle weight for rigid lorries without trailer.

The tyre inflation pressure shall be in line with the recommendation of the manufacturer. The tyres of the semitrailer may differ from the standard tyres set out in Table 2 of Part B of Annex II to Regulation (EC) No 661/2009 for the CO ₂ certification of tyres.

All settings influencing the auxiliary energy demand shall be set to minimum reasonable energy consumption where applicable. The air conditioning shall be switched off and venting of the cabin shall be set lower than medium mass flow. Additional energy consumers not necessary to run the vehicle shall be switched off. External devices to provide energy on board, such as external batteries, are allowed only for running the extra measurement equipment for the verification testing procedure listed in Table 2 but shall not provide energy to serial vehicle equipment.

A particle filter regeneration may be initiated and shall be achieved before the verification test. If an initiated particle filter regeneration cannot be achieved before the verification test, the test is invalid and shall be repeated.
