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.
