Proposal to clarify provisions of the headform tests of UN GTR No. 9.

Presentation of an assessment of 2D vs. 3D impactor positioning methods.

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).

Proposal to clarify figure 11 in the draft amendments to GTR No. 9 by substituting the description “Figure 11: Example of marking of HIC 1000 zone and HIC 1700 zone”.

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.

Draft text prepared by the Task Force Bumper Test Area (TF-BTA), a subgroup of the Informal Working Group on gtr No. 9 – Phase 2.
