Proposal from the Bumper Test Area Task Force, submitted as an alternative to the proposal in document GRSP/2014/17 as amended by document GRSP-56-38, to revise the procedure for determining the bumper test area under the pedestrian safety regulation. This proposal corrects shortcomings in the current definitions which could lead to a narrower test area than intended (leading to less effective pedestrian protection). This proposal includes a “bumper beam” determination method.

Proposal from the Bumper Test Area Task Force to revise the procedure for determining the bumper test area under the pedestrian safety regulation. This proposal corrects shortcomings in the current definitions which could lead to a narrower test area than intended (leading to less effective pedestrian protection). This proposal does not take into account potentially harmful hard structures such as bumper beams that may lie behind the outer contour or front fascia extending beyond the defined bumper corners as consensus within the task force could not be reached.

Updated presentation showing relative risks of injuries within and outside the proposed bumper test area and comparing late-model (post-2006) cars against earlier models based upon GIDAS data.

Request for clarification of test procedures for active pedestrian protection devices (such as active hood, pedestrian airbag).

Request for clarifications on the application of relaxation areas under UN Regulation No. 127.

The draft Amendment 2 to GTR No. 9 proposes to establish the new FlexPLI impactor as the single harmonized tool for lower leg impact tests. The amendment also proposes injury assessment reference values (IARV) to go with the FlexPLI. The US, however, has consistently expressed concerns that the proposed injury thresholds and IARV have not been validated as appropriate for the American car fleet. Therefore, the US proposes to have ‘recommended’ IARV included in the preamble to Amendment 2 while allowing governments the freedom to use whatever IARV/performance thresholds they deem appropriate until such criteria can be fully validated.

Proposal to amend the draft 01 series of amendments (document WP.29/2014/38 pending for the June 2014 WP.29 session) to bring its “commencement date” and validity-of-approvals provisions into line with the recommendations for the International Whole Vehicle Type Approval system (i.e., to set the effective date to 1 September 2018 and confirm the validity of earlier approvals after the introduction of the 01 series of amendments). This revised document also incorporates the Korean proposal to amend GTR No. 9 (document GRSP-55-24) and OICA proposal on Annex 5 (document GRSP-55-44).

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.
