It is applicable to impact tests involving:

— vehicles of category M1, except vehicles with the maximum mass above 2 500 kg and which are derived from N1 category vehicles and where the driver’s position, R-point, is either forward of the front axle or longitudinally rearwards of the front axle transverse centreline by a maximum of 1 100 mm;

— vehicles of category N1, except where the driver’s position, R-point, is either forward of the front axle or longitudinally rearwards of the front axle transverse centreline by a maximum of 1 100 mm;

— impacts to the bumper test area as defined by UN R127 [ 1 ] and UN GTR No.9 [ 2 ] ;

— pedestrian subsystem tests involving use of a legform for the purpose of evaluating compliance with vehicle safety standards.
