8. GRSG noted that the Executive Committee of the 1998 Agreement (AC.3) at its March 2024 session had adopted the authorization (ECE/TRANS/WP.29/2024/32) to develop amendments to UN GTRs Nos. 6, 7 (Head Restraints) and 14 (Pole side impact) which would allow the transfer of the reference, drawings and specification on the three-dimensional H- (3-D H-) point machine and calibration procedure from the UN GTRs to Mutual Resolution No. 1 (M.R.1). The expert from the Netherlands, which sponsors the amendment, introduced ECE/TRANS/WP.29/GRSG/2024/20 amending the UN GTR. Finally GRSG recommended ECE/TRANS/WP.29/GRSG/2024/20, not amended, as Amendment 4 to UN Regulation No. 6 to the November 2024 session of AC.3.
