This procedure establishes a recommended practice for establishing the sensitivity of the chest displacement potentiometer assembly used in the Hybrid III family of Anthropomorphic Test Devices (ATDs, or crash dummies). This potentiometer assembly is used in the Hybrid III family to measure the linear displacement of the sternum relative to the spine (referred to as chest compression). An inherent non-linearity exists in this measurement because a rotary potentiometer is being used to measure a generally linear displacement. As the chest cavity is compressed the potentiometer rotates, however the relationship between the compression and the potentiometer rotation (and voltage output) is non-linear. Crash testing facilities have in the past used a variety of techniques to calibrate the chest potentiometer, that is to establish a sensitivity value (mm/(volt/volt) or mm/(mvolt/volt)).

This procedure establishes a recommended practice for performing a Low Speed Knee Slider test to the Hybrid III 50th Male Anthropomorphic Test Device (ATD or crash dummy). This test was created to satisfy the demand from industry to have a certification test which produces similar results to an actual low energy automotive impact test. An inherent problem exists with the current certification procedure because the normal (2.75 m/s) knee slider test has test corridors that do not represent typical displacements seen in these low energy impact tests. The normal test corridors specify a force requirement at 10 mm and at 18 mm, while the low speed test needs to have a peak displacement around 10 mm.

This procedure establishes a recommended practice for performing a lumbar flexion test to the Hybrid III 50th male anthropomorphic test device (ATD or crash dummy). This test was created to satisfy the demand from industry to have a certification test which characterizes the lumbar without interaction of other dummy components. In the past, there have not been any tests to evaluate the performance of Hybrid III 50th lumbar.

Evaluation of the energy absorbing properties of the steering wheel assembly of a motor vehicle, or of the relative merit of alternative designs of such assemblies, is a complex problem involving human tolerance, vehicle and occupant dynamics during an accident, and frequency and severity of injuries to various body areas. Two fundamental approaches are being used currently for steering wheel assembly evaluations: laboratory impact tests of varying degrees of complexity, and simulated collision tests. This SAE Recommended Practice describes a simplified laboratory procedure for evaluating the characteristics of steering wheel assemblies under simulated driver impact conditions. Basically, the test procedure employs a torso shaped body block which is impacted against the steering wheel assembly and the transmitted load-time history is measured.
