This document provides definitions, symbols, mechanical requirements, certification test procedure, electronic subsystem requirements and user’s manual for advanced pedestrian legform impactor (aPLI), a standardized pedestrian legform impactor with an upper mass for pedestrian subsystem testing of road vehicles. 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];
