Working Party on General Safety | Session 112 | 24-28 Apr 2017
Geneva

The deadline for submission of official documents to the UNECE secretariat is 27 January 2017 (twelve weeks prior to the session).

Agenda Item 7.
Regulation No. 67

20. Referring to ECE/TRANS/WP.29/GRSG/2016/15, the expert from AEGPL recalled the purpose of his proposal 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. He confirmed that he had received in the meantime valuable feedback from a number of GRSG experts. He volunteered to prepare a revised proposal for consideration at the next session.

21. The expert from the Netherlands presented ECE/TRANS/WP.29/GRSG/2017/3 amending the provisions of UN Regulation No. 67 to use non-seamless gas tubes in LPG vehicles. The expert from AEGPL presented GRSG-112-19 inserting some improvements to the proposed provisions. GRSG noted general support and a number of comments. The expert from Germany raised a study reservation. Following the discussion, GRSG agreed to resume consideration of this subject at its next session in October 2017. In this respect, GRSG invited the experts from the Netherlands and AEGPL to prepare a combined document (see para. 20 above), taking into account the comments received and to submit it, in due time, to the secretariat for consideration and final review at the next GRSG session in October 2017.

22. The expert from Poland gave a presentation (GRSG-112-37) justifying his proposal ECE/TRANS/WP.29/GRSG/2017/10 to clarify the provisions for type approved accessories fitted to LPG containers. The proposal received some support. The expert from AEGPL presented GRSG-112-20 proposing, as an alternative, the additional marking of the accessories with the number of type approval extension. Following a controversial discussion, the expert from Poland proposed to set up either a task force or a new informal working group on gaseous fuelled vehicles to work on the best solution. His proposal to establish an IWG did not receive full support. Finally, GRSG agreed to resume consideration of this subject at its next session in October 2017 on the basis of a new proposal jointly prepared by Poland and AEGPL. Thus, GRSG invited all interested experts to send them, in due time, their written comments.

23. The expert from AEGPL presented GRSG-112-21 introducing tolerances for the dimensions of some filling units. A number of experts preferred to insert the corresponding specifications into the text of the UN Regulation instead of a reference to standard EN 22768-1. GRSG invited the expert from AEGPL to submit, in due time, an updated proposal for consideration at the next session of GRSG in October 2017.

24. The expert from Turkey introduced GRSG-112-22 proposing to develop new provisions on the location on the vehicle of the filling unit and a limitation of the service life of containers. A number of experts welcomed the initiative. GRSG invited the expert from Turkey to prepare a proposal for consideration at the next session of GRSG in October 2017.

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.

26. The expert from Germany proposed to also strengthen the requirements in UN Regulation No. 67 for the installation and inspection of LPG-containers and their accessories (GRSG-112-32). GRSG welcomed the proposal. The Chair invited all GRSG experts to send their comments, in due time, to the expert from Germany and proposed to resume consideration of this subject at the next session of GRSG on the basis of combined (see para. 25. above) proposal.
