| Document Title | UN R48: Proposal for a Supplement to the 09 series of amendments | ||||||||
| Reference Number | GRE/2024/5 | ||||||||

| Summary | Proposal to avoid exceeding the aggregate maximum intensity of the main-beam headlamps (430,000 cd) by removing the double requirement for a sum of reference marks and a sum of maximum luminous intensities which risks generating large rounding errors when the maximum luminous intensities are summed up. | ||||||||

13. The experts from GTB proposed several amendments that aligned the requirements in UN Regulation No. 48 with the updated requirements in UN Regulation No. 149 (ECE/TRANS/WP.29/GRE/2024/3), that aligned the requirements for the passing-beam vertical inclination for off-road vehicles between the 06, 07, 08 series and the 09 series of amendments to UN Regulation No. 48 (ECE/TRANS/WP.29/GRE/2024/4) and that avoided exceeding the aggregate maximum intensity of the main-beam headlamps (ECE/TRANS/WP.29/GRE/2024/5 as replaced by GRE-90-10). GRE adopted these proposals in principle and decided to postpone their submission to WP.29 and AC.1, in order to combine them in the future with other amendment proposals to the same series of amendments. 13.
