Precautions against electrostatic charges (ADR 7.5.10)

At its 103rd session (6–10 November 2017), in response to a question by the representative of Sweden (informal document INF.4), the Working Party confirmed the interpretation of Sweden, according to which, in order to meet the requirements of section 7.5.10, an earthing connection must be established with the vehicle chassis prior to the filling or emptying of tanks, either by means of a direct connection of the vehicle or tank to the earth or by connecting the vehicle or the tank to an earthed storage tank. See § 59 of report ECE/TRANS/WP.15/239.

Tunnel restrictions for dangerous goods with code "(-)" (ADR 8.6.4) 

At its 106th session (13–17 May 2019), in response to a question by the representative of France (informal document INF.13), the Working Party confirmed that the passage through road tunnels of vehicles containing dangerous goods, other than UN Nos. 2919 and 3331, for which “(-)” is indicated instead of a tunnel restriction code in column (15) of Table A of Chapter 3.2, could not be restricted for safety reasons. See § 55 of report ECE/TRANS/WP.15/246.

Sections of the vehicle certificate of approval (ADR 9.1.3.5)

The Working Party invited Latvia to incorporate this item as soon as possible into the new certificates. In the meantime, certificates issued without No. 13 could still be used. See § 52-53 of report ECE/TRANS/WP.15/246.
