Proposal to

1. introduce new safety provisions with regard to LPG systems having hydraulic interconnections with the petrol or diesel fueling system through which inter-flows of fuels may occur,
2. 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, and
3. require marking or other means of approval identification on accessories of the container (multivalve or, when approved separately, pressure relief valve (discharge valve) and pressure relief device).

Alternative solution from OICA to the German proposal GRSG/2017/16 regarding visibility/access requirements for PRV/PRD-related components in order to improve maintenance and reduce the risk of critical failures of pressure relief devices. The proposal also proposes amending provisions of the ageing test in Annex 15 in response to concerns over failures of rubber hoses.

The target of the meeting was to define essential periodic inspection requirements to be respected when installing gaseous fuel components into a vehicle, and to clarify the material requirements for components inside the LPG tank. The work addressed UN R67 and UN R110. No further meetings are planned at this time.

Proposal developed by the Gas-fueled Vehicle Regulations Task Force to facilitate periodic inspections of gas containers through better visibility. In addition, Germany suggests adding that paragraph to allow a Contracting Party or a regional organization of Contacting Parties like the EU to refuse national or regional type-approval and to refuse first registration of a vehicle type affected by the changes introduced by the 02 series of amendments but not meeting those stipulations. Paragraph 22.13 is an addition to paragraph 22.9. giving more stress to aspects of national and regional type-approval and of first registration of vehicles.

Proposal to insert type (item 1.1.) and pressure classification (item 1.2.) in the communication form (Annex 2B).

Proposal to define visibility requirements for external gas containers and their accessories to facilitate periodic inspections. From 1 September 2020, Contracting Parties may refuse approvals under the 01 series issued after 1 September 2020.
