7. The expert from the Republic of Korea informed GRSP that the Task Force on DPPS had become an IWG at the March 2018 sessions of WP.29 and AC.3 (see ECE/TRANS/WP.29/1137, paras. 44 and 155). However, he regretted the limited participation from contracting parties of both the 1958 and 1998 Agreements. He reiterated his encouragement for more contracting parties participation. He introduced the Status Report (GRSP-63-19) of the IWG and its terms of reference (GRSP-63-20), as agreed on by the experts at the first meeting of the IWG in Frankfurt (12-18 April 2018, Germany). A question was raised if the discussions on proposal for Amendment 3 could be merged with the proposal for Amendment 4. The expert from OICA recommended maintaining separate the two proposals of amendments on the new head-form test and DPPS to avoid disruption and delays. Finally, GRSP supported the request from the expert of the Republic of Korea to participate to the activities of the IWG. Finally, GRSP adopted GRSP-63-20 as reproduced in Annex II to this report and requested the expert from the Republic of Korea to submit it to the November 2018 sessions of WP.29 and AC.3.
