Discussions and Outcomes
176th WP.29 session (12-16 Nov 2018)

114. The Chair of GRSG presented proposals on ECE/TRANS/WP.29/2018/123 to ECE/TRANS/WP.29/2018/126 under agenda items 4.7.4 to 4.7.7, to amend UN Regulations Nos. 46, 67, 105 and 110. The World Forum recommended their submission to AC.1 for voting.

This proposal (WP.29/2018/124) was adopted by the World Forum. Thirty-four Contracting Parties out of the 43 applying UN R67 were present for the vote by AC.1. Thirty-four voted in favor with zero against and zero abstaining.
114th GRSG session (9-13 Apr 2018)

23. The expert from Germany introduced GRSG-114-08 on the recent meeting of the task force on gas-fuelled vehicle regulations held in Cologne (Germany) on 6 and 7 February 2018. He added that progress had been good on UN Regulation No. 110, but the amendments to UN Regulation No. 67 were still under considerations.

25. The expert from Germany recalled the outcome of the task force (para. 23 above) on ECE/TRANS/WP.29/GRSG/2017/16 and presented GRSG-114-09 proposing amendments to the Regulation. GRSG noted general support and some comments. Finally, GRSG considered a revised proposal (GRSG-114-09-Rev.1) and adopted ECE/TRANS/WP.29/GRSG/2017/16 as reproduced in Annex V to the session report. The secretariat was requested to submit the proposal to WP.29 and AC.1 as draft 02 series of amendments to UN Regulation No. 67 for consideration at their November 2018 sessions.

26. The expert from OICA introduced ECE/TRANS/WP.29/GRSG/2018/2 on amending the provisions of the ageing test in Annex 15 of UN Regulation No. 67 and on the results of the ageing of material (e.g. rubber hoses) that is in contact with LPG. GRSG invited the task force to resume consideration of this subject and to submit in due time a proposal for consideration at the next GRSG session. ECE/TRANS/WP.29/GRSG/2018/2 would be kept on the agenda as a reference document.

113th GRSG session (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.
