Note : 1. In case of Euro II and Euro III type approved norms =COP norms
2. In India there is also option for testing with engine dynamometer (in g/KWH) as thesecome under Diesel Light Duty Vehicles GVW < 3.5 tons
3. In European norms Passenger Car refers to Passenger Cars with seating capacity less than 6 and GVW less than 2.5 tons
