Proposal to establish a new UN Regulation on uniform provisions for the approval of passenger cars with regard to their occupant-restraint system performance in the event of a frontal collision (full width rigid barrier test).

Please note: para. 5.2.8.2. should read 5 liters, not 0.5 liters maximum allowable electrolyte spillage.

Proposal to increase the stringency of the Thorax Compression Criterion (ThCC) for the Hybrid III 5th female dummy in the passenger seat to 34 mm under the proposed new regulation to test the performance of occupant restraint systems in the event of a frontal collision. The transition date would be 1 September 2020.

Proposal to delete a reference to the measurement of the femur bending moments because such measurements are unnecessary under the full width rigid impact test. Specifically, paragraph 5.2.4.1. is changed from “The axial compressive force and the bending moments are measured with a CFC of 600.” to read “The axial compressive force is measured with a CFC of 600.”
