This SAE Recommended Practice describes the test procedures for conducting free motion headform testing of heavy truck cab interior surfaces and components. A description of the test set-up, instrumentation, impact configuration, target locations, and data reduction is included.
Rationale: This revision to the recommended practice aligns the impact speed with FMVSS 201 when heavy trucks are equipped with a dynamically deployed upper interior head protection system.
