Hybrid II 50th Male ATD

Hybrid II 50th Male

  • Standard ATD SA-150-M002

Our Hybrid II 50th Percentile Male ATD made history when it became the first repeatable and reproducible dummy mandated for motor vehicle safety testing. 

Originally designed by Alderson Research Laboratories, the dummy was modified by General Motors and the National Highway Traffic Safety Administration (NHTSA) using Alderson and Sierra Engineering parts. This produced a robust dummy that was capable of generating test data with sufficient biofidelity to be used for automotive crashworthiness testing. In 1973, the H-II 50M was mandated by NHTSA for use in testing automotive restraint systems to meet Federal Motor Vehicle Safety Standard No.208 (FMVSS 208).
