Road vehicles — Design and performance specifications for advanced Pedestrian Legform Impactor (aPLI)

Scope

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