the mass described in Paragraph 2.6. of Annex 1 to this Regulation and for vehicles designed and constructed for the carriage of more than 9 persons (in addition to the driver), the mass of a crew member (75 kg), if there is a crew seat amongst the nine or more seats.

              2.3.  "Maximum mass" means the technically permissible maximum mass declared by the vehicle manufacturer (this mass may be greater than the maximum               mass authorised by the national administration);
              2.4.  "Gaseous pollutants" means the exhaust gas emissions of carbon monoxide, oxides of nitrogen expressed in nitrogen dioxide (NO2) equivalent and hydrocarbons assuming ratio of:
                (a) C1H2.525 for liquefied petroleum gas (LPG)
                (b) C1H4 for natural gas (NG) and biomethane
                (c) C1H1.89O0.016 for petrol (E5)
                (d) C1H1.86O0.005 for diesel (B5)
                (e) C1H2.74O0.385 for ethanol (E85)
              2.5.  "Particulate pollutants" means components of the exhaust gas which are removed from the diluted exhaust gas at a maximum temperature of 325 K (52 °C) by means of the filters described in Annex 4a; Appendix 4.
              2.5.1. "Particle numbers" means the total number of particles of a diameter greater than 23 nm diameter present in the diluted exhaust gas after it has been conditioned to remove volatile material, as described in Annex 4a, Appendix 5.
              2.6. "Exhaust emissions" means
•    For positive-ignition (P.I.) engines, emissions of gaseous and particulate pollutants;
•    For compression-ignition (C.I.) engines, emissions of gaseous pollutants, particulate pollutants and particle numbers;
              2.7.  "Evaporative emissions" means the hydrocarbon vapours lost from the fuel system of a motor vehicle other than those from exhaust emissions;
              2.7.1.  "Tank breathing losses" are hydrocarbon emissions caused by temperature changes in the fuel tank (assuming a ratio of C1H2.33).
              2.7.2.  "Hot soak losses" are hydrocarbon emissions arising from the fuel system of a stationary vehicle after a period of driving (assuming a ratio of C1 H2.20 );
              2.8.  "Engine crankcase" means the spaces in or external to an engine which are connected to the oil sump by internal or external ducts through which gases and vapour can escape;
              2.9.  "Cold start device" means a device that temporarily enriches the air/fuel mixture of the engine thus assisting the engine to start;
              2.10.  "Starting aid" means a device which assists engine start up without enrichment of the air/fuel mixture of the engine, e.g. glow plug, injection timing change, etc.;
2.11.  "Engine capacity" means:
              2.11.1. For reciprocating piston engines, the nominal engine swept volume;
              2.11.2. For rotary piston engines (Wankel), twice the nominal swept volume of a combustion chamber per piston;
              2.12.  "Pollution control devices" means those components of a vehicle that control and/or limit exhaust and evaporative emissions.
              2.13.  "OBD" means an on-board diagnostic system for emission control, which has
