from vehicles mentioned above to M1, M2, N1 and N2               vehicles with a reference mass not exceeding 2,840 kg and which meet the               conditions laid down in this Regulation.

  2.  Definitions
  For the purposes of this Regulation the following definitions shall apply:
2.1.  "Vehicle type" means a group of vehicles that do not differ in the following   respects:
              2.1.1.  The equivalent inertia determined in relation to the reference mass as prescribed in Annex 4a, Table 3; and
           2.1.2.  The engine and vehicle characteristics as defined in Annex 1;
              2.2.  "Reference mass" means the "unladen mass" of the vehicle increased by a uniform figure of 100 kg for test according to Annexes 4a and 8;
              2.2.1.  "Unladen mass" means the mass of the vehicle in running order without the uniform mass of the driver of 75 kg, passengers or load, but with the fuel tank 90 per cent full and the usual set of tools and spare wheel on board, where applicable;
              2.2.2. "Running order mass" means 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
