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 improve the specifications for LPG multi-valves in response to an LPG vehicle fire that resulted in injuries to first responders. A German Type Approval Authority (KBA) analysis concluded that the hose connecting the PRV/PRD of the multi-valve to the gaseous phase was damaged and hose-fragments blocked both PRV and PRD such that pressure could not be adequately reduced. The PRV and PRD were activated, but the fragments considerably reduced the effective section of the relevant tubing and prevented the release of pressure. This proposal aims to prevent such occurrences.

Proposal to insert new provisions on the location on the vehicle of the filling unit, marking of the LPG container date of production, and a limitation on the maximum service life of LPG containers to 15 years.
