The Working Party on the Transport of Dangerous Goods (WP.15) during its 114th session noted, on the basis of INF.18 from Germany, 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.
Paragraph 9.2.2.8.3. of 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 document relates to the establishment of a GRSG task force on UN R46 to resolve this concern.
11. The expert from Germany, Chair of TF on UN Regulation No. 46 (Devices for indirect vision) introduced a status report (GRSG-127-28). He then introduced ECE/TRANS/WP.29/GRSG/2024/13 explaining that TF had considered a proposal submitted by the expert from Germany to start discussion on approving vehicles with battery master switches, in the framework of UN Regulation No. 105, that are fitted with a camera monitor system that complies with the requirements of UN Regulation No. 46. He added that the requirement may conflict with paragraph 16.1.1. of UN Regulation No. 46 which requires that, after each engine switch-off (intended use), the camera-monitor system remains operational for at least 120 seconds. Therefore, he introduced GRSG-127-04-Rev.2 to amend the UN Regulation. Finally GRSG adopted GRSG-127-04-Rev.2 as reproduced in annex II of this report. The secretariat was requested to submit GRSG-127-04-Rev.2, as draft Supplement 1 to the 06 series of amendments to UN Regulation No. 46 for consideration and vote to the November 2024 sessions of WP.29 and AC.1. Meanwhile, GRSG agreed to continue discussing the outcome of the TF work and to resolve the remaining issues at its October 2024 session.
55. The expert from OICA announced that he would prepare a proposal of amendment to the UN Regulation to align it with new ADR provisions. The expert from Spain clarified that this proposal differed from the activity of flammability in the TF he led (see paragraph 3 above) and reiterated his request to interested parties to liaise with him.
