UN R46: Alignment with UN R26 and R61

Five documents propose amendments to UN R46 series 02-07 to align requirements with UN R26 and UN R61, particularly regarding soft parts of camera monitoring systems and mirrors based on Shore A hardness. The 05 series introduced alignment requirements; harmonization is proposed for earlier series with existing approvals.

9. The expert from Germany, Chair of the Task Force on UN Regulation No. 46, presented the status report of the Task Force (GRSG 131 09). She also introduced documents ECE/TRANS/WP.29/GRSG/2026/25, ECE/TRANS/WP.29/GRSG/2026/26, ECE/TRANS/WP.29/GRSG/2026/27, ECE/TRANS/WP.29/GRSG/2026/28 and ECE/TRANS/WP.29/GRSG/2026/29, which propose a common alignment of UN Regulation No. 46 with UN Regulations Nos. 26 and 61 through the 02 to the 07 series of amendments to UN Regulation No. 46.
10. In light of document GRSG 131 12, submitted by the expert from Japan and amending ECE/TRANS/WP.29/GRSG/2026/30, the expert from Germany suggested that this proposal be reconsidered by the Task Force. At the same time, the expert from OICA introduced document GRSG 131 13, intended to clarify issues related to areas of opaque obscuration. GRSG agreed to forward this latter proposal to the Task Force for consideration.
11. GRSG adopted the following documents without amendment:
(a) ECE/TRANS/WP.29/GRSG/2026/25, as draft Supplement 06 to the 02 Series of Amendments to UN Regulation No. 46;
