Draft BioRID Dummy Certification Procedures to ensure proper dummy performance. These procedures include multiple tests to verify system inputs and two tests to verify dummy performance.

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.

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).

Proposal revising an initial German proposal to reduce the risk of a person being unintentionally locked inside a vehicle by an anti-theft system.

Proposal to remove the specification of “±0.01 m/sec” for the accuracy of the velocity measurement in Annex 5, Paragraph 3.2.1. This would leave in place the specification to use the measurement procedure if ISO 3784:1976 which specifies an accuracy of ±1 %.

The Working Party on Passive Safety approved this proposal provided that Australia would seek guidance on its transitional provisions (since this amendment would, in principle, be adopted at the same time as the original PSI regulation at the November 2014 WP.29 session). This draft incorporates comments from Germany, Japan, and OICA received after the GRSP 55th session.
