to the first decimal place.

       5.2.4. For the purpose of the calculation mentioned in paragraph 5.2.3., the fuel consumption shall be expressed in appropriate units and the following fuel characteristics shall be used:
           (a) Density: measured on the test fuel according to ISO 3675 or an equivalent method. For petrol, diesel, biodiesel and ethanol (E85) the density measured at 15 ºC will be used; for LPG and natural gas/biomethane a reference density will be used, as follows:
              0.538 kg/litre for LPG
              0.654 kg/m3 for NG[3]/;
           (b) Hydrogen-carbon ratio:  fixed values will be used which are:
              C1H1,89O0,016 for petrol (E5);
              C1H1,86O0,005 for diesel (B5);
              C1H2,525 for LPG (liquefied petroleum gas) ;
              CH4 for NG (natural gas) and biomethane;
              C1H2,74O0,385 for ethanol (E85)."

        5.3. Description of tests for vehicles powered by an electric power train only

        5.3.1. The technical service in charge of the tests conducts the measurement of the electric energy consumption according to the method and test cycle described in Annex 7 to this Regulation.

        5.3.2. The technical service in charge of the tests conducts the measurement of the electric range of the vehicle according to the method described in Annex 9.

         The electric range measured by this method is the only one which may be included in sales promotional material.

        5.3.3. The result of the electric energy consumption must be expressed in Watt hours per kilometre (Wh/km) and the range in km, both rounded to the nearest whole number.

5.4 Description of tests for vehicles powered by a hybrid electric power train

        5.4.1. The technical service in charge of the tests conducts the measurement of the emissions of CO2 and of the electric energy consumption according to the test procedure described in Annex 8.

        5.4.2. The results of the test for CO2 emissions must be expressed in grams per kilometre (g/km) rounded to the nearest whole number.

        5.4.3. Fuel consumption values must be expressed in litres per 100 km (in the case of petrol, LPG or diesel) or in m3 per 100 km (in the case of NG), and are calculated according to paragraph 1.4.3. of Annex 6 by the carbon balance method using the measured emissions of CO2 and the other carbon related emissions (CO and HC).  The results will be rounded to the first decimal place.

        5.4.4. For the purpose of the calculation mentioned in paragraph 5.4.3., the prescriptions and values of paragraph 5.2.4. shall apply.

        5.4.5. If applicable, the result of the electric energy consumption must be expressed in Watt hours per kilometre (Wh/km), rounded to the nearest whole number.

        5.4.6. The technical service in charge of the tests conducts the measurement of the electric range of the vehicle according to the method described in Annex
