Proposal from the Netherlands to amend UN R67 in order to permit approval of higher pressure LPG direct injection components like the fuel pump, the fuel rail, the injectors and a safety valve leading back fuel from the high pressure parts to the fuel tank.

Proposal to allow the use of Class 0 hoses with couplings using sealing technologies other than those with a 45° cone. Currently, non-seamless double and single wall tubes are used in brake and fuel tubing applications, allowing for the use of a variety of end forms and coupling techniques. Provided the tubing can withstand the applicable tests according to Annex 15, Table 1, such configurations should be permitted under UN R67 in order to remove an unwarranted design restriction.

Proposal of corrections to document GRSG/2016/7. The wording of the original proposal opens the possible interpretation that the regulation allows materials other than copper, stainless steel, or steel with corrosion-resistant coatings for gas tubes. The intention of the proposal was only to allow for “non-seamless” gas tubing. The original proposal is therefore modified to allow Class 0/I hoses with couplings using gas tubes of other than seamless material.

Proposal to amend the provisions of UN R67 (R67) in order to enable the approval of non-seamless double and single wall gas tubes provided they can withstand the applicable tests according to Annex 15.

Proposal, as modified pursuant to discussions during the October 2016 GRSG session, to amend the provisions of UN R67 (R67) in order to enable the approval of non-seamless double and single wall gas tubes provided they can withstand the applicable tests according to Annex 15.

Proposal to establish procedures for the approval of non-seamless double and single wall gas tubes provided they can withstand the applicable tests according to Annex 15.

Proposal to establish procedures for the approval of non-seamless gas tube(s), gas tube(s) made of materials other than copper, stainless steel, and steel with corrosion-resistant coating, and their couplings in Liquefied Petroleum Gas (LPG) vehicles provided they can withstand the applicable tests according to Annex 15.

Proposal presented as an alternative to the previous proposal from Poland (GRSG/2017/10) to require manufacturers to mark the approval extension number on any accessories relevant to the bonfire test (multivalve or, when approved separately, pressure relief valve (discharge valve) and pressure relief device) so that the fitting of any accessory not on the list of approved configurations (Table 3 in the appendix of Annex 2B) will be prevented/forbidden. This solution would imply a new requirement in Annex 2A for the marking of the accessories fitted to the containers.

Proposal to require marking of extension numbers on accessories relevant to the UN R67 bonfire test (e.g., multivalve, pressure relief valve, pressure relief device) in order to prevent/prohibit the misuse (in container configurations) of these accessories. The proposal includes provisions for components where such marking is impractical based upon text drawn from UN R46.

Proposal to update vehicle-fuel identification symbols in alignment with ISO 17840-4, Part 4 (Propulsion energy identification) and to extent the scope of the fuel identification requirements to include N₂ and N₃ vehicles.

Proposal from the GRSG task force on Automated Vehicles Regulation Screening to enable application of UN R67 to ADS vehicles. In the absence of a driver/driver’s compartment/manual driving controls in the vehicle, provisions related to them shall not be taken into account if not already covered by this amendment. The proposal clarifies provisions for vehicles with a separate driver’s compartment.

Proposal prepared by the Task Force on Automated Vehicles Regulatory Screening (TF-AVRS), with the aim to amend and supersede document ECE/TRANS/GRSG/2025/25.
