| Y-category vehicle crashworthiness: Proposal for a new UN Regulation |
| Reference Number: GRSP-TF-AVRS-29-05 |
|
Task force in-session amendments to the proposal to establish uniform provisions for approval of vehicles of category N1Y regarding protection of fuel system integrity, protection against electrical shock, and vehicle crash compatibility. Requirements address liquid fuel leakage limits, compressed hydrogen storage system integrity including leakage rates and container retention, high voltage electrical system protection through absence of high voltage, low electrical energy, physical protection, or isolation resistance, electrolyte leakage limits for rechargeable energy storage systems, REESS retention, fire and explosion hazards, and crash compatibility criteria. Testing includes frontal collision per UN R94 or UN R137, lateral collision per UN R95, and rear-end collision per UN R153. Vehicles derived from approved N1 types complying with specified series may demonstrate compliance through previous test results. |

| Lamps Under Parked Conditions: Report of the 12th (September 2026) session |
| Reference Number: LUPC-12-05/Rev.1 |
|
Draft report of the 12th session of the Task Force on Lamps Under Parked Conditions. Discussion of a proposal for modification of UN R48 covered additional colours for energy indicators, with concerns raised regarding blue indicators and police signals, the number of indicators permitted per connector, distinction between passenger cars and trucks/buses, and observation angles and intensities. Agreement was reached on the size of apparent surface for indicators. The group decided to continue discussion on lamp test mode at the next session and to send a status report, revised Terms of Reference, and an informal proposal to the 95th session of GRE. |
