4.8.4. | Proposal for Supplement 15 to the 01 series of amendments to UN Regulation No. 67 (LPG vehicles)
6. (a) | Amendments to gas-fuelled vehicle regulations: Regulation No. 67 (LPG vehicles)

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)”.

7. | Regulation No. 67 (LPG vehicles)

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.
