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.

42. The expert from Liquid Gas Europe introduced the proposal for amending UN Regulation No. 67 (ECE/TRANS/WP.29/GRSG/2020/23). He highlighted a correction that was required in the title of the document, which when modified should read: Proposal for Supplement 03 to the 02 series of amendments to UN Regulation No. 67 (LPG vehicles).

43. GRSG adopted ECE/TRANS/WP.29/GRSG/2020/23, proposal for amendment to UN Regulation No. 67, as amended during the session, and agreed to submit it for consideration and vote at the March 2021 session of WP.29/AC.1.

Proposal to clarify that the correct procedure for a type I test of a hybrid electric vehicle under UN R115 shall take into account Annex 14 of UN R83.

27. The expert from Liquid Gas Europe introduced ECE/TRANS/WP.29/GRPE/2020/11, as amended by GRPE-81-37. The proposal was supported by the representative from Italy. The representative from the UK requested some clarifications around the notion of special provisions in the context of UN Regulation No. 115. The expert from Liquid Gas Europe agreed to add more clarity in forthcoming amendment proposals and to ease the processing in the case of specific vehicle technologies for Type Approval Authorities (TAAs).

28. GRPE adopted ECE/TRANS/WP.29/GRPE/2020/11 and GRPE-81-37, as amended by Annex VI and requested the secretariat to submit Annex VI to WP.29 and AC.1 for consideration and vote at their November 2020 sessions as draft Supplement 9 to UN Regulation No. 115 (LPG and CNG retrofit systems).

40. The representative from Liquid Gas Europe introduced GRPE-80-20 correcting errors in ECE/TRANS/WP.29/2019/45. The representative from Italy agreed ECE/TRANS/WP.29/2019/45 contained some errors that needed to be addressed in the fastest way possible by the secretariat. The secretariat submitted GRPE-80-20 as ECE/TRANS/WP.29/2020/49 as a Proposal for Corrigendum 1 to Supplement 8 to UN Regulation No .115 (LPG and CNG retrofit systems) that was to be considered by WP.29 and AC.1 at their March 2020 sessions.

45. The expert from LG Europe introduced GRSG-117-52. GRSG requested the secretariat to verify the different language versions of UN Regulation No. 67 as inconsistencies have been detected and to rectify them by issuing an erratum.

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).

36. The expert from Poland recalled the purpose of ECE/TRANS/WP.29/GRSG/2018/8 to adapt the Regulation to technical progress, specifically for the definition of a type of container and Annex 2B. The expert from LG Europe introduced ECE/TRANS/WP.29/GRSG/2018/20 as a counterproposal. A number of experts welcomed the amendments to Annex 2B, but could not support the amendments to the definition of “Type of container”. After discussion, GRSG adopted ECE/TRANS/WP.29/GRSG/2018/20 except the amendments to paragraph 2.4. The secretariat was requested to submit the proposal as amended to WP.29 and AC.1 as draft Supplement 16 to the 01 series of amendments and as draft Supplement 1 to the 02 series of amendments to UN Regulation No. 67 for consideration at their March 2019 sessions.

AEGPL views on the proposal to align Regulation No.115 to the new WLTC test cycle, defined in the GTR 15 and in the Commission Regulation (EU) 2017/1151 and later modifications.

39. The expert from Italy introduced GRPE-77-09 on the need to update UN Regulation No. 115 and the need to introduce a reference to WLTP instead of emission tests performed on the basis of the former test cycle (New European Driving Cycle (NEDC)). He proposed to host a meeting with all interested parties in order to develop a working document that would be presented at the January 2019 session of GRPE. He mentioned the letter from the expert of AEGPL showed support to the idea and interest to participate in the activities (GRPE-77-23). He stated that the difficulty for this work was that WLTC was not yet included in a UN Regulation but in a UN GTR.

In the absence of complete harmonization with ISO 11439, this proposal recommends that Table 6.4 of UN R110 should be amended by the following for CNG-1 designs:

1. Delete A.17, A.25, and A.7 since they do not match the tests specified in paragraph 7.5 on Cylinder design qualification tests
2. Add A.15 and A.6 since they do match the tests specified in paragraph 7.5 on Cylinder design qualification tests
3. Add A.24 because paragraph 6.9 on Fire protection requires all PRDs on all cylinder types to comply with A.24.

32. The expert from NGV Global introduced ECE/TRANS/WP.29/GRSG/2018/3 that proposed to correct Table 6.4 on the cylinder design qualification tests. GRSG adopted the proposal and requested the secretariat to submit the proposal to WP.29 and AC.1, for consideration at their November 2018 sessions, as Corrigendum 1 to Revision 3 of UN Regulation No. 110.

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.

34. Finally, GRSG considered a revised proposal (GRSG-113-36) and adopted ECE/TRANS/WP.29/GRSG/2017/30 as amended below.

Part I, paragraph 4.2., amend to read:

35. The secretariat was requested to submit the proposal to WP.29 and AC.1 as part (see paras. 31 and 32 above) of draft Supplement 15 to the 01 series of amendments to UN Regulation No. 67 for consideration at their March 2018 sessions.

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.

30. The expert from Turkey introduced ECE/TRANS/WP.29/GRSG/2017/22 proposing to insert new provisions on the location on the vehicle of the filling unit and a limitation of the service life of LPG containers. The expert from OICA introduced a counter proposal for transitional provisions (GRSG-113-19). The expert from AEGPL raised concerns on the location of filling unit on the vehicle and the limitation of the service life of LPG containers. He proposed to amend the provisions on the location of the filling unit and to insert a limitation of the service life as reflected in GRSG-113-32. GRSG noted a number of comments and study reservations. Following the discussion, the expert from Turkey volunteered to prepare a revised proposal for consideration at the next GRSG session, taking into account the comments received.

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.

31. The expert from AEGPL presented ECE/TRANS/WP.29/GRSG/2017/26 proposing to insert new safety provisions into UN Regulation No. 67 on LPG systems that have hydraulic interconnections with the petrol or diesel fuelling system through which inter-flows of fuels may occur. GRSG adopted the proposal, as amended below, and requested the secretariat to submit it to WP.29 and AC.1 as draft Supplement 15 to the 01 series of amendments to UN Regulation No. 67 for consideration at their March 2018 sessions.

New paragraph 2.22., replace “Interconnected LPG-system” by “Interconnected LPG-system (ICS)”.

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.

32. Referring to ECE/TRANS/WP.29/GRSG/2017/27, the expert from AEGPL recalled the purpose of his proposal to clarify the provisions in UN Regulation No. 67 on the use of non-seamless gas tubes in LPG vehicles. GRSG adopted the document, as amended below, and requested the secretariat to submit it to WP.29 and AC.1 as part (see para. 31 above) of draft Supplement 15 to the 01 series of amendments to UN Regulation No. 67 for consideration at their March 2018 sessions.

Paragraph 2.2., subparagraph (s), amend to read:

“(s) Non-seamless and seamless gas tubes and their couplings;”

New paragraph 17.7.1.2., amend to read:

Annex 15, paragraph 5., replace “Only longitudinal welding” by “Only straight longitudinal welding”.

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.

33. Recalling the discussion on ECE/TRANS/WP.29/GRSG/2017/10 at the previous GRSG session, the expert from AEGPL presented ECE/TRANS/WP.29/GRSG/2017/30 to further clarify the provisions for type approved accessories fitted to LPG containers and to insert an additional indication mark. The expert from Poland raised a study reservation and introduced the obligation to mark the products with the designation of the version, variant and the extension number of the type-approval certificate (GRSG-113-09). Both proposals received a number of comments.

34. Finally, GRSG considered a revised proposal (GRSG-113-36) and adopted ECE/TRANS/WP.29/GRSG/2017/30 as amended below.

Part I, paragraph 4.2., amend to read:

35. The secretariat was requested to submit the proposal to WP.29 and AC.1 as part (see paras. 31 and 32 above) of draft Supplement 15 to the 01 series of amendments to UN Regulation No. 67 for consideration at their March 2018 sessions.

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.

21. The expert from the Netherlands presented ECE/TRANS/WP.29/GRSG/2017/3 amending the provisions of UN Regulation No. 67 to use non-seamless gas tubes in LPG vehicles. The expert from AEGPL presented GRSG-112-19 inserting some improvements to the proposed provisions. GRSG noted general support and a number of comments. The expert from Germany raised a study reservation. Following the discussion, GRSG agreed to resume consideration of this subject at its next session in October 2017. In this respect, GRSG invited the experts from the Netherlands and AEGPL to prepare a combined document (see para. 20 above), taking into account the comments received and to submit it, in due time, to the secretariat for consideration and final review at the next GRSG session in October 2017.

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.

22. The expert from Poland gave a presentation (GRSG-112-37) justifying his proposal ECE/TRANS/WP.29/GRSG/2017/10 to clarify the provisions for type approved accessories fitted to LPG containers. The proposal received some support. The expert from AEGPL presented GRSG-112-20 proposing, as an alternative, the additional marking of the accessories with the number of type approval extension. Following a controversial discussion, the expert from Poland proposed to set up either a task force or a new informal working group on gaseous fuelled vehicles to work on the best solution. His proposal to establish an IWG did not receive full support. Finally, GRSG agreed to resume consideration of this subject at its next session in October 2017 on the basis of a new proposal jointly prepared by Poland and AEGPL. Thus, GRSG invited all interested experts to send them, in due time, their written comments.

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.

23. The expert from AEGPL presented GRSG-112-21 introducing tolerances for the dimensions of some filling units. A number of experts preferred to insert the corresponding specifications into the text of the UN Regulation instead of a reference to standard EN 22768-1. GRSG invited the expert from AEGPL to submit, in due time, an updated proposal for consideration at the next session of GRSG in October 2017.

Proposal to restrict the application of CO2 specific emission limits only to NMHC and CO emissions (back-to-back comparison of NOx and PM to apply under the regulation in any case). The proposal also aligns the text where applicable with the intent of paragraph 2.3.15.: “R49 original emission limits” means the emission limits as defined in Regulation No. 49 to which the original engine system was approved."

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.

25. The expert from AEGPL introduced ECE/TRANS/WP.29/GRSG/2016/15 which proposes to insert new safety provisions into UN Regulation No. 67 on Liquefied Petroleum Gas (LPG) systems having hydraulic interconnections with the petrol or diesel fuelling system through which inter-flows of fuels might occur. The expert from Germany objected to the adoption of the proposal as safety risks (overfill of tank) still remain, particularly, since a small amount of flow of petrol into the LPG tank was still possible. The expert from the United Kingdom underlined the need to cross-check all references of paragraphs in the proposal. GRSG agreed to have a final review of the proposal at its next session in April 2017 on the basis of a revised document to be submitted by AEGPL.

20. Referring to ECE/TRANS/WP.29/GRSG/2016/15, the expert from AEGPL recalled the purpose of his proposal to insert new safety provisions into UN Regulation No. 67 on Liquefied Petroleum Gas (LPG) systems having hydraulic interconnections with the petrol or diesel fuelling system through which inter-flows of fuels might occur. He confirmed that he had received in the meantime valuable feedback from a number of GRSG experts. He volunteered to prepare a revised proposal for consideration at the next session.

Amendments to the proposal as presented in document GRPE/2016/12.

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.

25. The expert from AEGPL introduced GRSG-110-13, superseding his proposal ECE/TRANS/WP.29/GRSG/2015/35 and proposing new provisions to prevent a flow of liquefied petroleum gas (LPG) into the petrol or diesel tank, and vice versa. GRSG noted general support on the updated proposal. Following a study reservation by the expert from France, GRSG decided to have a final review of the proposal at its next session in October 2016 and requested the secretariat to circulate GRSG-110-13 with an official symbol.
