Text prepared by the Chair of the Task Force on Liquefied Natural Gas (LNG) vehicles (on the basis of document GRSG/2013/7) to introduce type approval provisions for vehicles equipped with LNG propulsion systems. The proposal has been prepared as a new consolidated version (Revision 3) of UN Regulation No. 110.

Proposal from the GFV Informal Group. FC_mean, as defined in paragraphs 6.1.2.4.3.2. (LPG) and 6.2.2.4.3.2. (CNG) of UN Regulation No. 115, is the mean value of the fuel consumptions of all the parent (test) vehicles, whereas the calculation of the gas ratio has to be made individually for each parent vehicle.

Therefore, FC_mean has to be replaced by FC_norm as defined in UN R101.

This correction would align UN R115 with the corresponding provisions set out in UN R83

Text from the Informal Group on Gaseous Fuelled Vehicles in order to comply with a request by the GRSG. Amendments proposed by the LNG Task Force on incorporating LNG systems into Regulation 110 were approved by the 104th session of the GRSG (GRSG/2013/7). The German delegate, recognizing that potential methane release — venting from ‘boil off’ — is an environmental issue suggested that the issue of holding time for LNG and its venting be brought forward to the GRPE.

Information provided to GRPE at the request of GRSG to explain the nature of LNG container venting as a safety precaution responding to LNG boil-off effects on pressure levels.

Text prepared by the Euro VI Expert Working Group of the European Commission to revise the 06 series of amendments to UN R49 in order to address situations that were not covered by the latest series of amendments and to clarify the text.
