               is the volume of the diluted gas, in litres per test (prior to correction);
                   is the volume of gas delivered by the positive displacement pump in testing conditions, litres per pump revolution;
                   is the number of revolutions per test.
              2.2.1.1. Correcting the volume to standard conditions
              The diluted exhaust gas volume, V, shall be corrected to standard conditions according to the following equation:
              where:
               is the test room barometric pressure, kPa;
                   is the vacuum at the inlet of the positive displacement pump relative to the ambient barometric pressure, kPa;
                   is the arithmetic average temperature of the diluted exhaust gas entering the positive displacement pump during the test, Kelvin (K).
              3. Mass emissions
              3.1. General requirements (as applicable)
              3.1.1. Assuming no compressibility effects, all gases involved in the engine's intake, combustion and exhaust processes may be considered to be ideal according to Avogadro's hypothesis.
              3.1.2. The mass  of gaseous compounds emitted by the vehicle during the test shall be determined by the product of the volumetric concentration of the gas in question and the volume of the diluted exhaust gas with due regard for the following densities under the reference conditions of 273.15 K (0 °C) and 101.325 kPa:
              Carbon monoxide (CO)  g/l
              Carbon dioxide (CO2)  g/l
              Hydrocarbons:
               for petrol (E0) (C1H1.85)  g/1
               for petrol (E10) (C1H1.93 O0.033)  g/l
               for diesel
