               1. Scope and application
               This Regulation aims at providing a worldwide harmonized method to determine the levels of Real Driving Emissions (RDE) of gaseous compounds and particles from light-duty vehicles.

              This Regulation applies to the type approval of vehicles of categories M1 with a reference mass not exceeding 2,610 kg and vehicles of categories M2 and N1 with a reference mass not exceeding 2,610 kg and a technical permissible maximum laden mass not exceeding 3,500 kg with regard to their Real Driving Emissions.

              At the manufacturer's request, type approval granted under this Regulation may be extended from vehicles mentioned above to vehicles of categories M1 with a reference mass not exceeding 2,840 kg and vehicles of categories M2 and N1 with a reference mass not exceeding 2,840 kg and a technical permissible maximum laden mass not exceeding 3,500 kg and which meet the conditions laid down in this Regulation.

              Pure Electric Vehicles and Fuel Cell Vehicles are out of the scope of this Regulation.
