This International Standard specifies a method of measurement of variations of motor vehicle passing beam inclination, with respect to its initial inclination, caused by the changes in vehicle attitude due to loading. This method of measurement may particularly be used during vehicle type approval tests.
Loading conditions of the vehicles are specified in annex A. They are to be used except when legal regulations require loading conditions which are different.
