Statement of US concerns with the draft amendment to introduce the Flex PLI test tool into GTR No. 9 (document GRSP/2013/25) in particular with regard to the use of the injury assessment reference values (IARVs). US definition of the IARV will be dependent upon the outcome of a US cost-benefit analysis based upon the characteristics of the American vehicle population. The US cannot accept injury curves that do not fall within what is justifiable according to US traffic conditions.

Phase 2 of GTR No. includes proposals for injury assessment reference values (IARV). The United States has asserted that the IARV have not been sufficiently validated through cost-benefit analysis, which is a requirement in US rulemaking. Therefore, the US has proposed to permit regulators to select IARV that correspond to their local vehicle populations. However, adding this qualification (through a footnote) would create a precedent for future GTR and OICA has lamented that such diversity in application hampers the goal of harmonization. Therefore, the GTR 9 informal group and GRSP are putting this issue before the World Forum for guidance.

Report on the development of the Flex-PLI legform impactor and its use within pedestrian protection performance testing.

Progress report on the second-phase development of the GTR on pedestrian safety focused on the introduction of the flexible pedestrian legform impactor (FlexPLI) as a single harmonized test tool in order to enhance the level of protection for lower legs of pedestrians.
