Proposal to amend the transitional provisions of UN Regulation No. 67 and clarify the validity of type approvals according 01 series of this regulation for components not affected by modifications introduced by 02 series of amendments.

Proposal to amend the transitional provisions of UN Regulation No. 67 and clarify the validity of type approvals according 01 series of this regulation for components not affected by modifications introduced by 02 series of amendments.

GRSG to review the text prepared by the expert from Italy to amend UN R67 to introduce the new filling unit profile “J15” as specified in ISO 19825 and to align with the same standard the naming of Euro filling unit.

Proposal to align UN Regulation No. 67 with ISO 19825 by changing the name of the light vehicle Euro filling unit to K15 and inserting a new profile J15 into Annex 9.

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.

Proposal to improve the specifications for LPG multi-valves in order to reduce the risks of blockage of the PRV/PRD due to deterioration of the hose connecting the PRV/PRD of the multi-valve to the gaseous phase.

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 introduce new provisions on the location on the vehicle of the filling unit in order to address

• Difficulties with filling the LPG container (e.g., the filler pistol may be unable to fit the space between ground and filling unit when the vehicle is fully laden)
• Risks involved on occupational health and safety of LPG container filling operators (e.g. necessity to kneel or lie down to fill the fuel containter).

Proposals to amend or supersede the proposal in document GRSG-116-05. Liquid Gas Europe opposes the proposal to add an odorant in the n-pentane.

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

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.

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

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.

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.

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.

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).

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.

1. Document GRSG/2017/22 proposed by Turkey raised concerns regarding the location on the vehicle of the filling unit and a limitation of the service life of LPG containers
2. In order to prevent a proliferation of different service-life specifications, AEGPL proposes a fixed mandatory service live of 10 years.

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.

OICA proposal of modifications to the Turkey 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. Given that the risks concern containers located outside and under the vehicle, OICA proposes focusing discussion of the 15-year service life on such containers. In addition, the proposal would introduce new requirements and therefore would require transitional provisions.

Proposal to modify the type-approval certificate as specified in Annex 2B by introducing additional points:

1. Type (point 2-type of equipment)
2. its version (point 3)
3. variant (point 4) and pressure classification
4. (point 5 – include the component’s working pressure for class 0)

Proposal to require labeling of products with the designation of the version, variant and the number of type-approval certificate extension based on which the product was approved for sale in order to ensure linking of the technical documentation with the product designation and to improve the ability to verify the design of the components.

Proposal to delete “trade name” from the approval definition in order to avoid strict interpretations where a manufacturer would be obliged to define a new container type designation whenever the tank’s trade name is updated (whereas the trade name is inconsequential in terms of product approval).

Proposal for 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.

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 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.

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.

Presentation supporting GRSG/2017/10 to clarify the definitions of LPG container accessories to facilitate coordination between the separate, independent approvals required for the LPG container and for its accessories.

Proposal to allow for the approval of systems using non-seamless double and single wall tubes subject to testing for high pressure and high resistance to pressure pulses. The proposal would also add general test requirements for LPG fuel lines and couplings based on ISO Standard 15500 for compressed natural gas equipment.

In GRSG/2017/10, Poland proposes requirements for the LPG tank and its accessories. AEGPL notes that UN R67 requires a specific bonfire test of the container equipped with specific configurations of accessories which includes markings to indicate the extension number of each accessory corresponding to each configuration. In order to ensure that the user knows whether an accessory can be fitted with a specific container, AEGPL proposes to require marking the extension number on the accessories relevant to the bonfire test (multivalve, pressure relief valve and pressure relief device) in order to prevent/forbid the fitting of any accessory not approved for use in each container configuration. This alternative proposal to that in GRSG/2017/10 would imply a new marking requirement for accessories, but would avoid the proliferation of accessory type-approval numbers and increase in paperwork.

Proposal to introduce tolerances for dish, bayonet, and acme filling units in order to reduce risks of misuse in connecting these filling units with nozzles.

Proposal to introduce a maximum service life requirement of 15 years and for the location of the filling unit of the LPG tank on vehicles.

Proposal to require that components connecting the pressure relief device with the gaseous phase be made of metal.

Proposal to establish a requirement for easy access to the LPG container installation in order to permit visual (periodical) inspection as a means to reduce the safety risks, such as refueling explosion, due to corrosion.

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 clarify the definitions of LPG container accessories to facilitate coordination between the separate, independent approvals required for the LPG container and for its accessories. The proposal aims to ensure proper coordination between container approvals (which involve testing with accessories attached) and accessory approvals (which may be subsequent to the original container approval and therefore, relevant to its validity).

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 clarify the definitions of LPG container accessories to facilitate coordination between the separate, independent approvals required for the LPG container and for its accessories. The proposal does not introduce any changes in technical requirements or changes in the test methodology. The proposed changes are intended to prevent the possibility of improper selection of accessories for the tank, which could arise due to lack of clear provisions of type-approval certificates issued for accessories fitted to the container.

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 for 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.

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 insert 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.

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 to amend UN R67 to allow for limited flows of petrol into the LPG tank of dual fuel vehicles, taking into account comments received during the 109th GRSG session.

Presentation on the proposal to allow for limited flows of petrol into the LPG tank of dual fuel vehicles.

Proposal to revise the AEGPL proposal concerning dual fuel systems (GRSG/2015/35). The proposal introduces ISO 26262:2011 (functional safety of electric/electronic systems) as the basis for assessing safety functions. Germany proposes to require resistance against diesel fuel in addition to petrol fuel (Annex 18). Furthermore, the proposal would require manufacturers to provide a full listing of the parts incorporated within the system to ensure that testing services and approval authorities have a clear understanding of any elements that may be safety-related.

Proposal to amend UN R67 to allow for limited flows of petrol into the LPG tank of dual fuel vehicles.

In document GRSG/2013/29, the AEGPL proposed to introduce new provisions into Regulation No. 67 for preventing the flow of liquefied petroleum gas (LPG) into the petrol or diesel tank, and vice versa in order to address a potential safety risk in bi-fuel or dual-fuel vehicles. At the 105th GRSG session, Germany requested a more detailed test procedure. Therefore, this proposal responds to the German request, improves certain descriptions of requirements, and provides comments to justify the various provisions.

Proposal to introduce type-approval provisions for “valve control at stop-start” into the regulation on LPG equipment. The proposal would allow tank valves stay open in a commanded stop-start phase as is the case for the idling phase of non-stop-start vehicles. These provisions are similar to those for UN R110 on CNG vehicles.
