  "heading": "Emissions of gaseous and particulate pollutants and of CO2 and NH3",
  "text": "The pollutants are represented by:\n(a) Oxides of nitrogen, NOx;\n(b) Hydrocarbons, expressed as total hydrocarbons, HC or THC;\n(c) Carbon monoxide, CO;\n(d) Particulate matter, PM;\n(e) Particle number, PN.\nThe measured values of gaseous and particulate pollutants and of CO 2 exhausted by the engine refer to the brake-specific emissions in grams per kilowatt-hour (g/kWh), or number per kilowatt-hour (#/kWh) for PN.\nThe gaseous and particulate pollutants that shall be measured are those for which limit values are applicable to the engine sub-category being tested as set out in Annex II to Regulation (EU) 2016/1628. The results, inclusive of:\n(a) the crankcase emissions determined in accordance with section 6.10, if relevant,\n(b) the adjustment factors for infrequent regeneration of the after-treatment system determined in accordance with section 6.6, if relevant, and\n(c) as the final step of the calculation, the deterioration factor determined in accordance with Annex III,\nshall not exceed the applicable limit values.\nThe CO 2 shall be measured and reported for all engine sub-categories as required by Article 43(4) of Regulation (EU) 2016/1628.\nThe mean emission of ammonia (NH3) shall additionally be measured, as required in accordance with section 3 of Annex IV, when the NOx control measures that are part of the engine emission control system include use of a reagent, and shall not exceed the values set out in that section.\nThe emissions shall be determined on the duty cycles (steady-state and/or transient test cycles), as described in section 7 and in Annex XVII. The measurement systems shall meet the calibration and performance checks set out in section 8 with the measurement equipment described in section 9.\nOther systems or analysers may be approved by the approval authority if it is found that they yield equivalent results in accordance with point 5.1.1. The results shall be calculated according to the requirements of Annex VII.",
