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.
38. The expert from OICA recalled the purpose of ECE/TRANS/WP.29/GRSG/2018/2 and informed GRSG that parts of the proposal had been adopted and that the remaining parts had recently been reviewed by TF on gas-fuelled vehicle regulations. The expert from Germany reported on the good TF work progress force. He presented GRSG-116-05 on the outcome of TF discussions on UN Regulation No. 67. The expert from LG Europe proposed to remove the requirements for the use of an odorant in n-pentane: such requirements were not necessary and not requested in any test in the UN Regulations or in international standards (GRSG-116-39). After discussion, GRSG agreed on the revised proposal GRSG-116-05-Rev.1 and adopted ECE/TRANS/WP.29/GRSG/2018/2 as reproduced in Annex III to this report. The secretariat was requested to submit the revised proposal to WP.29 and AC.1 as draft Supplement 2 to the 02 series of amendments to UN Regulation No. 67 for consideration at their November 2019 sessions.
33. The expert from Germany reported on the work progress of the task force on gas-fuelled vehicle regulations during its meeting in Cologne (Germany) on 27 and 28 February 2018 (GRSG-115-05). GRSG welcomed the information.
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.
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.
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.
