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

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.

11. Finally, the expert from OICA introduced GRSG-125-30, to clarify the provisions of the UN Regulation to allow foldable wings for camera monitoring systems (CMS). The experts from United Kingdom suggested that the proposal should clarify the deployment time of the CMS. GRSG agreed to resume discussion at its October 2023 session on a revised proposal submitted by the expert from OICA. GRSG also noted that if a new replacement proposal was not received by the secretariat, GRSG-125-30 should be confirmed for submission as an official document before the deadline.
