This procedure establishes a recommended practice for performing a Low Speed Knee Slider test to the Hybrid III 50thMale Anthropomorphic Test Device (ATD or crash dummy). This test was created to satisfy the demand from industry tohave a certification test which produces similar results to an actual low energy automotive impact test. An inherentproblem 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 aforce requirement at 10 mm and at 18 mm, while the low speed test needs to have a peak displacement around 10 mm.1.1 PurposeThe intent of this recommended practice is to develop a low speed knee slider test procedure for the H-III50M dummy witha 10 mm deflection range.
