5.11 Data evaluation for gaseous emissions

  5.11.1 For the evaluation of the gaseous emissions, the data recorded for at least the last 60 seconds of each mode shall be averaged, and the concentrations of CO, CO2, HC, NOx, and O2 during each mode shall be determined from the averaged recorded data and the corresponding zero and span check data. The averaged results shall be given in terms of % to not fewer than two decimal places for CO2 and O2 species and in terms of ppm to at least the nearest whole number for CO, HC and NOxspecies.
