UN R46: Proposal for Supplement 1 to the 06 series of amendments

Document GRSG-127-04/Rev.1

13 April 2024

127th GRSG session (15-19 Apr)

The Working Party on the Transport of Dangerous Goods (WP.15) has noted that problems could arise during the approval of vehicles intended for the carriage of explosive substances and articles (Class 1) for vehicles intended for the carriage of liquids having a flash-point of not more than 60°C. (EX/III and FL vehicles) fitted with a camera monitoring system which complied with the requirements of UN R46.

The European Agreement concerning the International Carriage of Dangerous Goods by Road (ADR) stipulates that the electrical circuits must be broken within 10 seconds after operation of the battery master switch. This might conflict with paragraph 16.1.1. of UN R46 which requires that, after each engine switch-off (intended use), the camera-monitor system remains operational for a period of at least 120 seconds.

This proposal aims to resolve the disparity between UN R46 and requirements for ADS vehicles.
