適用范圍：This International Standard specifies a method of measuring variations in the dipped-beam headlamp angle of motor vehicles from the initial angle, caused by changes in vehicle at-titude due to loading. This measurement method may be used particularly during vehicle type approval tests.Loading conditions of vehicles are specified in annex A. They are to be used except when legal regulations require different loading conditions.Annex B establishes a classification of headlamps, and gives examples of measurement methods applicable according to the classification. Annex C gives a photometric method of deter-mining the position of a point of the conventional cut-off, which is complementary to one of the measurement method examples in annex B.
