4. (a) | UN Regulation No. 46 (Devices for indirect vision)

9. The expert from Germany, Chair of TF on UN Regulation No. 46 (Devices for indirect vision) introduced TF status report (GRSG-126-23). He then introduced GRSG-126-24-Rev.1 amending the UN Regulation on those parts agreed so far by TF as a new series of amendments. Many of the experts were in favour of the pendulum with a diameter of 165 ± 1 mm and a 5 ± 1 mm thick rubber covering for the impact test. Finally, GRSG adopted ECE/TRANS/WP.29/GRSG/2023/23 as amended by GRSG-126-24-Rev.1 and GRSG-126-25-Rev.1. The secretariat was requested to submit GRSG-126-25-Rev.1 as draft Supplement 1 to the 05 series of amendments (as reproduced by annex III to the report) and ECE/TRANS/WP.29/GRSG/2023/23 (as amended by annex III to the report) as draft 06 series of amendments to UN Regulation No. 46, for consideration and vote at the March 2024 sessions of WP.29 and AC.1. GRSG agreed that TF work would continue to solve the remaining issues in UN Regulation No. 46.

10. The expert from OICA introduced ECE/TRANS/WP.29/GRSG/2023/9 which aims to introduce provisions adapted to centre-steered vehicles of categories M2, M3, N2 and N3. The expert from Germany raised a study reservation on the proposal and requested full feedback for the October 2023 session of GRSG. He suggested in the meantime to establish a TF to provide a thorough proposal of amendments to the UN Regulation at the next session of GRSG. The experts from France and the Netherlands supported the suggestion from the expert of Germany expressing the need of a thorough study of the magnification factors. Moreover, the expert from OICA introduced ECE/TRANS/WP.29/GRSG/2023/16 and amendment GRSG-125-03-Rev.1, on the provisions for exterior rear-view mirrors fixed to the protective housing. At the same time the expert from the Republic Korea introduced GRSG-125-24 that shows two different interpretations of the diameter of the sphere used for the impact test rig in UN Regulation No. 46, and compares it to similar headforms used in other UN Regulations and in UN GTR No. 9. The expert from Canada confirmed that in his national standard, the outer diameter was 165 mm. Finally, GRSG endorsed the establishment of a TF led by the expert from Germany with the expert from OICA for secretary tasks, and agreed on ECE/TRANS/WP.29/GRSG/2023/9, ECE/TRANS/WP.29/GRSG/2023/16, GRSG-125-03-Rev.1 and GRSG-125-24 as a basis for its work.
