For the purposes of this Regulation, the following definitions shall apply:

1. (1)

   ‘CO₂ emissions and fuel consumption related properties’ means specific properties derived for a component, separate technical unit and system which determine the impact of the part on the CO₂ emissions and fuel consumption of a vehicle;

2. (2)

   ‘input data’ means information on the CO₂ emissions and fuel consumption related properties of a component, separate technical unit or system which is used by the simulation tool for the purpose of determining CO₂ emissions and fuel consumption of a vehicle;

3. (3)

   ‘input information’ means information relating to the characteristics of a vehicle which is used by the simulation tool for the purposes of determining their CO₂ emissions and fuel consumption of the vehicle and which is not part of an input data;

4. (4)

   ‘manufacturer’ means the person or body who is responsible to the approval authority for all aspects of the certification process and for ensuring conformity of CO₂ emissions and fuel consumption related properties of components, separate technical units and systems. It is not essential that the person or body be directly involved in all stages of the construction of the component, separate technical unit or system which is the subject of the certification.

5. (4a)

   F2‘vehicle manufacturer’ means a body or person responsible for issuing the manufacturer's records file and the customer information file pursuant to Article 9;

6. (5)

   ‘authorised entity’ means a national authority authorised by a Member State to request relevant information from the manufacturers and vehicle manufacturers on the CO₂ emissions and fuel consumption related properties of a specific component, specific separate technical unit or specific system and CO₂ emissions and fuel consumption of new vehicles respectively.

7. (6)

   ‘transmission’ means a device consisting of at least of two shiftable gears, changing torque and speed with defined ratios;

8. (7)

   F1‘torque converter’ means a hydrodynamic start-up component either as a separate component of the driveline or transmission with serial or parallel power flow that adapts speed between engine and wheel and provides torque multiplication;

9. (8)

   ‘other torque transferring component’ or ‘OTTC’ means a rotating component attached to the driveline which produces torque losses dependent on its own rotational speed;

10. (9)

    ‘additional driveline component’ or ‘ADC’ means a rotating component of the driveline which transfers or distributes power to other driveline components and produces torque losses dependant on its own rotational speed;

11. (10)

    ‘axle’ means a central shaft for a rotating wheel or gear as drive axle of a vehicle;

12. (11)

    ‘air drag’ means characteristic of a vehicle configuration regarding aerodynamic force acting on the vehicle opposite to the direction of air flow and determined as a product of the drag coefficient and the cross sectional area for zero crosswind conditions;

13. (12)

    ‘auxiliaries’ means vehicle components including an engine fan, steering system, electric system, pneumatic system and air conditioning (AC) system whose CO₂ emissions and fuel consumption properties have been defined in Annex IX;

14. (13)

    ‘component family’, ‘separate technical unit family’ or ‘system family’ means a manufacturer's grouping of components, separate technical units or systems, respectively, which through their design have similar CO₂ emissions and fuel consumption related properties;

15. (14)

    ‘parent component’, ‘parent separate technical unit’ or ‘parent system’ means a component, separate technical unit or system, respectively, selected from a component, separate technical unit or system family, respectively, in such a way that its CO₂ emissions and fuel consumption related properties will be the worst case for that component family, separate technical unit family or system family;

16. (15)

    ‘F2zero emission heavy-duty vehicle’ or ‘ZE-HDV’ means a heavy-duty vehicle without an internal combustion engine, or with an internal combustion engine that emits less than 1 g CO₂/kWh;

17. (16)

    ‘vocational vehicle’ means a heavy-duty vehicle not intended for the delivery of goods and for which one of the following digits is used to supplement the bodywork codes, as listed in Appendix 2 to Annex II of Directive 2007/46/EC: 09, 10, 15, 16, 18, 19, 20, 23, 24, 25, 26, 27, 28, 31; or a tractor with a maximum speed not exceeding 79 km/h;

18. (17)

    ‘rigid lorry’ means a lorry that is not designed or constructed for the towing of a semi-trailer;

19. (18)

    ‘tractor’ means a tractor unit that is designed and constructed exclusively or principally to tow semi-trailers;

20. (19)

    ‘sleeper cab’ means a type of cabin that has a compartment behind the driver's seat intended to be used for sleeping;

21. (20)

    ‘hybrid electric heavy-duty vehicle’ or ‘He-HDV’ is as defined in Article 3(15) of Directive 2007/46/EC;

22. (21)

    ‘dual-fuel vehicle’ is as defined in Article 2(48) of Regulation (EU) No 582/2011.

F2With regard to He-HDVs, Articles 5(3), 9(1) and 12(1) shall apply only to He-HDVs where the second highest maximum net power of all energy converters is less than 10 % of the highest maximum net power of all energy converters. Energy converters used only for the starting are in this respect not taken into consideration.
