Proposal to clarify the application of GTR 7 Phase 2 static alternative provisions and to modify the allowed range of tolerances under the backset retention and energy dissipations test.

6. Finally, GRSP experts were invited to provide comments to GRSP-64-39-Rev.1 and GRSP-64-40 to the expert from Japan by the end of January 2019. Moreover, it was agreed that IWG organize a webex meeting to allow the expert from Japan to submit an official proposal of amendments, which would also incorporate GRSP-64-25 (see para. 16 of this report) by 15 February 2019.

16. The experts from Japan and EC introduced GRSP-64-37 on the proposal of amendments (ECE/TRANS/WP.29/GRSP/2018/34) to UN Regulation No. 17 (Strength of seats) that would align it with Phase 2 of UN GTR No. 7 (see para. 5 above). The expert from CLEPA introduced GRSP-64-25, to clarify static alternative provisions of UN GTR No. 7, Phase 2 and modifications to the allowed range of tolerances to backset retention and to the energy dissipation test. GRSP agreed to hand over GRSP-64-25 to the IWG for its possible integration in the proposal of amendments to UN Regulation No. 17 and to the draft amendment to UN GTR No. 7. GRSP agreed to resume discussion on this subject at its May 2019 session on the basis of the progress of the IWG work.

Proposal to amend the dynamic option of the draft 10 series of amendments (document GRSP/2018/34). CLEPA proposes that injury risk limits should be based not only on the injury risk curves, but also on technical feasibility given the repeatability and reproducibility limits of the BioRID II test tool. This proposal also corrects the definition of T(end) which is different from T-HRC.

Proposal to clarify the application of GTR 7 Phase 2 static alternative provisions and to modify the allowed range of tolerances under the backset retention and energy dissipations test. The proposal would re-introduce certain paragraphs in the 09 series of amendments removed by the draft 10 series (GRSP/2018/34). In addition, the proposals adds the area where the gap measurement procedure by the sphere is appropriate per the Federal Motor Vehicle Safety Standard 202a (i.e. only gaps in the area over 540 mm).

12. The expert from Japan introduced ECE/TRANS/WP.29/GRSP/2020/8 in a presentation (GRSP-67-17) on behalf of the Task Force on aligning UN Regulation No. 17 with UN GTR No. 7, Phase 2 provisions. The expert from Italy requested a delay on transitional provision for all new vehicles (paragraphs. 13.13.2 and 13.13.3). Finally, GRSP adopted ECE/TRANS/WP.29/GRSP/2020/8, as amended by Annex IV to the session report. The secretariat was requested to submit the proposal as the draft 10 series of amendment to UN Regulation No. 17, for consideration and vote at the November 2020 sessions of WP.29 and AC.1. At the same time, the expert from CLEPA withdrew ECE/TRANS/WP.29/GRSP/2019/9.

Proposal on behalf of the Drafting Task Force to transpose UN Global Technical Regulation No. 7, Phase 2 (GTR7-PH2) into UN Regulation No. 17.
