UN R83: Proposal for a new Supplement to the 06 and 07 series of amendments

Proposal to clarify the fuel tank capacity restriction for mono-fuel gas vehicles. The definition of “mono-fuel gas vehicle” was slightly amended between the 06 and the 07 series of amendments to UN R83. This proposal aims to align the definitions across both series in order to avoid divergent interpretations.
Although the reference to a 15 liters tank has always been understood to refer to the nominal capacity of the tank, the use of the term “nominal capacity” in UN GTR No. 19 in several places other than the definition of “mono-fuel gas vehicle” can lead to other interpretations of the definition. The word “nominal” should therefore be inserted into the definition in both series of amendments.
