The aPLI has a redesigned knee assembly, with a rounded impact area, rerouted ligament cables and a redesigned condyle, which improves the impactor response. A Simplified Upper Body Part (SUBP), representing a portion of human torso mass, adds ballast to the assembly, improves the response of the femur and allows injury risk assessment for this body region.

It distributes the mass in a more humanlike manner and provides a secure placement for the instrumentation’s Data Acquisition System (DAS). A one-piece moulded flesh assembly further contributes to a realistic mass distribution and biofidelic response of the legform.

The aPLI was finalised through ISO/TC22/SC36/WG5&WG6 as part of a round robin evaluation.
