The vehicle tested in accordance with the first paragraph shall be considered as complying if, in addition to requirements set out in points (a), (e) and (g) of point 1.1.3., the following requirements are met: (a) if the NG/biomethane fuel is the reference fuel G20, the emission result for each pollutant shall be multiplied by the relevant factors (r1 for the first test and r2 for the second test), calculated in section 1.1.2.5, if the relevant factor > 1; if the correspondent relevant factor < 1, no correction is needed; (b) if the NG/biomethane fuel is the reference fuel G25, the emission result for each pollutant shall be divided by the correspondent relevant factor (r1 for the first test and r2 for the second test) calculated in accordance with point 1.1.2.5, if the correspondent relevant factor < 1; if the correspondent relevant factor > 1, no correction is needed; (c) on the manufacturer's request the type 1 test must be performed with the four possible combinations of reference fuels, according to section 1.1.2.5, so that no correction is needed; (d) if repeated tests are made on the same engine the results on reference fuel G20, or H2G20, and those on reference fuel G25, or H2G25 with the maximum hydrogen percentage specified by the manufacturer, shall first be averaged; the “r1” and “r2” factors shall then be calculated from these averaged results.’; (i) Figure I.2.4 is replaced by the following: ‘Figure I.2.4 Application of test requirements for type approval and extensions Vehicle category Vehicles with positive ignition engines including hybrids Vehicles with compression ignition engines including hybrids Pure electric vehicles Hydrogen Fuel cell vehicles Mono fuel Bi-fuel (1) Flex-fuel (1) Flex fuel Mono fuel Reference fuel Petrol (E5) LPG NG/Biomethane Hydrogen Petrol (E5) Petrol (E5) Petrol (E5) Petrol (E5) NG/Biomethane Diesel (B5) Diesel (B5) — — LPG NG/Biomethane Hydrogen Ethanol (E85) H2NG Biodiesel Gaseous pollutants (Type 1 test) Yes Yes Yes Yes (4) Yes (both fuels) Yes (both fuels) Yes (both fuels) (4) Yes (both fuels) Yes (both fuels) Yes (B5 only) (2) Yes — — Particulate mass and particulate number (Type 1 test) Yes — — — Yes (petrol only) Yes (petrol only) Yes (petrol only) Yes (both fuels) — Yes (B5 only) (2) Yes — — Idle emissions (Type 2 test) Yes Yes Yes — Yes (both fuels) Yes (both fuels) Yes (petrol only) Yes (both fuels) Yes (NG/biomethane only) — — — — Crankcase emissions (Type 3 test) Yes Yes Yes — Yes (petrol only) Yes (petrol only) Yes (petrol only) Yes (petrol only) Yes (NG/biomethane only) — — — — Evaporative emissions (Type 4 test) Yes — — — Yes (petrol only) Yes (petrol only) Yes (petrol only) Yes (petrol only) — — — — — Durability (Type 5 test) Yes Yes Yes Yes Yes (petrol only) Yes (petrol only) Yes (petrol only) Yes (petrol only) Yes (NG/biomethane only) Yes (B5 only) (2) Yes — — Low temperature emissions (Type 6 test) Yes — — — Yes (petrol only) Yes (petrol only) Yes (petrol only) Yes (3) (both fuels) — — — — — In-service conformity Yes Yes Yes Yes Yes (both fuels) Yes (both fuels) Yes (both fuels) Yes (both fuels) Yes (both fuels) Yes (B5 only) (2) Yes — — On-board diagnostics Yes Yes Yes Yes Yes Yes Yes Yes Yes Yes Yes — — CO2 emissions, fuel consumption, electric energy consumption and electric range Yes Yes Yes Yes Yes (both fuels) Yes (both fuels) Yes (both fuels) Yes (both fuels) Yes (both fuels) Yes (B5 only) (2) Yes Yes Yes Smoke opacity — — — — — — — — — Yes (B5 only) (2) Yes — — (j) Point 4.9 is replaced by the following: ‘4.9.
