      ‘2.2.3.

      Calculations of the conformity factors

      The conformity factors shall be calculated for each individual valid averaging window and each individual gaseous pollutant in the following way:

      $$\mathrm{CF}=\frac{e_{\mathrm{gas}}}{L}$$

      Where:

      • e_gas is the brake-specific emission of the gaseous pollutant, g/kWh;

      • L is the applicable limit, g/kWh.’;

   3. (c)

   4. (d)

      in point 2.3.1, in the legend for the equation, the indent relating to P _max is replaced by the following:

      • ‘ P _max is the maximum net power, as defined in Article 3(28) of Regulation (EU) 2016/1628, kW.’;

   5. (e)

      point 2.3.2 is replaced by the following:

      ‘2.3.2.

      Calculations of the conformity factors

      The conformity factors shall be calculated for each individual averaging window and each individual pollutant in the following way:

      $$\mathrm{CF}=\frac{{\mathrm{CF}}_I}{{\mathrm{CF}}_C}$$

      With

      • ${\mathrm{CF}}_I=\frac{m_i}{m_{{\mathrm{CO}}_2}\left(t_{\mathrm{2,}i}\right)-m_{{\mathrm{CO}}_2}\left(t_{\mathrm{1,}i}\right)}$ (in service ratio) and

      • ${\mathrm{CF}}_C=\frac{m_L}{m_{{\mathrm{CO}}_{\mathrm{2,}\mathrm{ref}}}}$ (certification ratio)
