10 Test report

This standard specifies the principles, conditions and procedures of the test methods to measure the road performances of the partially electrically propelled road vehicles (Hybrid vehicles). This standard is applicable to the concept of road performances which comprises the notions of speed, acceleration, hill climbing ability. This standard applies to the international categories of vehicles M1, M2, M3, N1, N2, N3, and to motor tricycles and quadricycles from t the motocycles types. This standard does not apply to pure electric propelled road vehicles.
