LNG Task Force update, including review of issues concerning dangerous-goods transport vehicles (ADR vehicles).

Document from the Working Party on the Transport of Dangerous Goods (WP.15) concerning the use of LNG fuels under discussion within the WP.29 GFV informal working group.

Since the 1960’s diesel has been the predominant fuel used for the propulsion of heavy goods vehicles. Fuel-related requirements for dangerous goods (ADR) vehicles have been based upon this prevalence; however, duel fuel vehicles using CNG and LNG have raised issues concerning the use of such fuel systems on ADR vehicles. This paper discusses ADR vehicles and such gaseous fuels.
