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.

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.
