Proposal prepared by the experts of the Informal Working Group (IWG) on Global Technical Regulation No. 9 Phase 2 (GTR9-PH2) and proposes provisions on pedestrian safety and motor vehicles. It represents the final proposal of the Informal Group for Phase 2 of GTR No. 9, based on document GRSP/2014/15 proposing to introduce the Flex PLI lower legform impactor and related test procedures into the GTR on pedestrian safety protection, including the new bumper test area specifications.. As such, the document incorporates also the results of the Task Force Bumper Test Area as well as the comments provided in the informal document of the US from last December’s GRSP (GRSP/2017/3).

Draft of the amendment to introduce the Flex PLI lower legform impactor and related test procedures into the GTR on pedestrian safety protection, including the new bumper test area specifications.

Proposal to amend the bumper test area procedures under the pedestrian safety GTR.
This proposal includes the “bumper beam measurement” in the procedure.

Proposal to modify document GRSP/2014/15 presenting Amendment 2 to GTR No. 9. Amendment 2 would introduce the flexible pedestrian legform impactor (FlexPLI) as a single harmonized test tool. The National Highway Traffic Safety Administration (NHTSA) has expressed concern whether the injury assessment reference values (IARV) proposed in Amendment 2 will be able to meet the needs for injury mitigation in the United States of America. In order to allow the amendment to move forward, the United States proposes to accept the IARV while noting in the statement of technical rationale and justification its continuing research into the IARVs and the possibility of a future proposal to amend the values should this prove warranted.
