This agenda item relates to UN R67 LPG Equipment.
Working Party on General Safety | Session 109 | 29 Sep-2 Oct 2015

27. The expert from AEGPL gave a presentation (GRSG-109-15) justifying the insertion into UN Regulation No. 67 of new provisions to prevent a flow of liquefied petroleum gas (LPG) into the petrol or diesel tank, and vice versa (ECE/TRANS/WP.29/GRSG/2015/35). The expert from Spain raised concerns on the possible interpretation of the new provisions and preferred clear test requirements. The experts from France and Sweden endorsed that position. The expert from Germany introduced GRSG-109-12 proposing some improved text to ECE/TRANS/WP.29/GRSG/2015/35. He raised concerns on the possible leakage of the different fuel types and questioned the need to install redundant valves.

28. Following the discussion, the expert from AEGPL introduced GRSG-109-21 superseding ECE/TRANS/WP.29/GRSG/2015/35. The experts from France and Spain raised a study reservation. Thus, GRSG agreed to resume consideration of this subject at its next session on the basis of a revised proposal by AEGPL, taking into account the comments received.
