Overview

ISO 11096:2011 - Road vehicles - Pedestrian protection - Impact test method for pedestrian thigh, leg and knee specifies a standardized laboratory method to simulate a lateral impact between the front of a passenger car (or light truck derived from passenger cars) and an adult pedestrian’s lower limb. The standard focuses on reducing thigh, leg and knee injuries by defining the legform impactor, test site, propulsion, test conditions and measurement requirements. It is not applicable to other body regions, children, human soft tissue assessment, or vehicles with deployable pedestrian‑activation devices.

Key topics and technical requirements

• Legform impactor design
  • Based on a 50th percentile adult male; cylindrical shape with outer diameter 120 ± 10 mm and simulated flesh/skin thickness 30 ± 5 mm.
  • Overall mass 13.4 ± 0.1 kg (thigh 8.6 ± 0.1 kg, leg 4.8 ± 0.1 kg).
  • Leg length (to knee center) 493 ± 5 mm; thigh length 428 ± 5 mm; specified moments of inertia and centers of gravity.
  • Knee joint with deformable elements; biofidelic performance targets are given (Annex A) and certification procedures are in Annex B.
• Propulsion and kinematics
  • Impactor is propelled in free flight to strike a stationary vehicle; propulsion method is at the test lab’s discretion.
  • Trajectory tolerance: parallel to ground within ±6° at impact; angular velocity
