type 1 test was performed in compliance with the previous paragraph.

              For dedicated compression ignition engines fuelled with ethanol (ED95), a fixed carbon-hydrogen-oxygen ratio shall be used for the purposes of calculating fuel consumption values, which shall be C1H2.92O0.46.

              A.1.2.1.2. Paragraph 5.2.4. of Regulation No. 101 shall be understood as follows:
                  (1) Density: measured on the test fuel according to ISO 3675 or an equivalent method. For petrol, diesel, ethanol (E85) and ethanol for dedicated C.I. engines (ED95) the density measured at 288 K (15 °C) will be used; for LPG and natural gas/biomethane a reference density shall be used, as follows:
                   0.538 kg/litre for LPG;
                  0.654 kg/m3 for NG.
              (2) Hydrogen-carbon-oxygen ratio: fixed values shall be used which are:
                  C1H1.93O0.032 for petrol (E10);

                  C1H1.86O0.006 for diesel (B7);

                  C1H2.525 for LPG (liquefied petroleum gas);

                  CH4 for NG (natural gas) and biomethane;
                  C1H2.74O0.385 for ethanol (E85);
              C1H2.92O0.46 for ethanol for dedicated C.I. engines (ED95).
              A.1.2.1.3. Paragraph 1.4.3. of Annex 6. of Regulation No. 101 shall be understood as:
              "1.4.3. The fuel consumption, expressed in litres per 100 km (in the case of petrol, LPG, ethanol (E85 and ED95) and diesel) or in m3 per 100 km (in the case of NG/biomethane) is calculated by means of the following formulae:
              (a) For vehicles with a positive ignition engine fuelled with petrol (E10):
                  FC = (0.120/D) ∙ [(0.831 ∙ HC) + (0.429 ∙ CO) + (0.273 ∙ CO2)]
              (b) For vehicles with a positive ignition engine fuelled with LPG:
                  FCnorm = (0.1212/0.538) ∙ [(0.825 ∙ HC) + (0.429 ∙ CO) + (0.273 ∙ CO2)]
                  If the composition of the fuel used for the test differs from the composition that is assumed for the calculation of the normalised consumption, on the manufacturer's request a correction factor cf may be applied, as follows:
                  FCnorm = (0.1212/0.538) ∙ (cf) ∙ [(0.825 ∙ HC) + (0.429 ∙ CO) + (0.273 ∙ CO2)]
                  The correction factor cf, which may be applied, is determined as follows:
                  cf = 0.825 + 0.0693 nactual
                  Where:
                  nactual is the actual H/C ratio of the fuel used
(c) For vehicles with a positive ignition engine fuelled with NG/biomethane:
                  FCnorm = (0.1336/0.654) ∙ [(0.749 ∙ HC) + (0.429 ∙ CO) + (0.273 ∙ CO2)]
(d) For vehicles with a positive ignition engine fuelled with ethanol (E85):
 FC = (0.1742/D) ∙ [(0.574 ∙ HC) + (0.429 ∙ CO) + (0.273 ∙ CO2)]
(e) For vehicles with a compression ignition engine fuelled with diesel (B7):
              FC = (0.1165/D) ∙ [(0.859 ∙ HC) + (0.429 ∙ CO) + (0.273 ∙ CO2)]
(f) For vehicles with a dedicated compression ignition engine fuelled with ethanol (ED95)
              FC = (0.186/D) ∙ [(0.538 ∙ HC) + (0.429 ∙ CO) + (0.273
