This agenda item relates to UN R67 LPG Equipment.
Working Party on General Safety | Session 111 | 11-14 Oct 2016

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.

Working Party on General Safety | Session 112 | 24-28 Apr 2017

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.

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.

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.

24. The expert from Turkey introduced GRSG-112-22 proposing to develop new provisions on the location on the vehicle of the filling unit and a limitation of the service life of containers. A number of experts welcomed the initiative. GRSG invited the expert from Turkey to prepare a proposal for consideration at the next session of GRSG in October 2017.

25. Reporting on a severe incident which happened in 2014 (GRSG-112-31), the expert from Germany proposed a new series of amendments to UN Regulation No. 67 to enhance the specifications for the LPG multi-valve. The experts from Italy, the Netherlands and Poland confirmed such risks and endorsed the need to adopt such new provisions. The expert from Germany volunteered to submit an official document for consideration at the next GRSG sessions, including transitional provisions.

26. The expert from Germany proposed to also strengthen the requirements in UN Regulation No. 67 for the installation and inspection of LPG-containers and their accessories (GRSG-112-32). GRSG welcomed the proposal. The Chair invited all GRSG experts to send their comments, in due time, to the expert from Germany and proposed to resume consideration of this subject at the next session of GRSG on the basis of combined (see para. 25. above) proposal.

32. Reporting on some cases of structural failures of cylinders in his country, the expert from Italy proposed amendments to Annex 3A on the test requirements for the periodic requalification of cylinders (GRSG-112-28). The expert from Finland stated that these test requirements on periodical inspections of CNG/LNG vehicles in use were only recommendations to be taken into account during the type approval procedure of a new type of vehicle. GRSG noted that Contracting Parties were used to perform on their national level the periodical technical inspections in different ways. Referring to GRSG-112-32 presented under agenda item 7 (see para. 26 above), the expert from Germany introduced GRSG-112-33 proposing to also strengthen the requirements in UN Regulation No. 110 for the installation on vehicles of CNG-cylinders, LNG-tanks and their accessories as well as for their subsequent inspection of without the need of disassembling the containers.

33. GRSG noted general support on the proposals. The Chair invited all GRSG experts to send their comments, in due time, to the experts from Germany and Italy. GRSG agreed to resume consideration of this subject at its next session on the basis of official documents, prepared by Germany and Italy, taking into account the comments received.

Working Party on General Safety | Session 113 | 10-13 Oct 2017

28. The expert from Germany presented ECE/TRANS/WP.29/GRSG/2017/16 that amends the provisions of UN Regulation No. 67 to improve the specifications for the Liquefied Petroleum Gas (LPG) connecting the pressure relief valve with the gaseous phase for multi-valve in the vehicle tanks and those for the installation and inspection of LPG containers and their accessories. The expert from OICA introduced GRSG-113-18 on modifications to the aging test requirements of some rubber materials and on further transitional provisions. The expert from AEGPL endorsed the proposal to avoid a ban of some technologies and materials. Both proposals received a number of comments.

29. GRSG agreed on the need to revise the requirements on pipes for multivalves on LPG containers and to keep, at the same time, the testing provisions technology neutral. Thus, GRSG agreed to set up a Task Force under the leadership of Germany to find a compromise and to prepare a revised proposal for consideration at the next GRSG. It was also agreed to keep ECE/TRANS/WP.29/GRSG/2017/16 on the agenda as a reference document. The secretariat was requested, in the absence of a revised proposal by the task force, to circulate GRSG-113-18 with an official symbol.

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.

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:

“4.2. All equipment shall have …… drawings referred to in paragraph 3.2.2. above. In the case of limited space for the approval mark(s), other means of identification that link it to the approval mark shall be provided.
