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.
