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.
30. The expert from Turkey introduced ECE/TRANS/WP.29/GRSG/2017/22 proposing to insert new provisions on the location on the vehicle of the filling unit and a limitation of the service life of LPG containers. The expert from OICA introduced a counter proposal for transitional provisions (GRSG-113-19). The expert from AEGPL raised concerns on the location of filling unit on the vehicle and the limitation of the service life of LPG containers. He proposed to amend the provisions on the location of the filling unit and to insert a limitation of the service life as reflected in GRSG-113-32. GRSG noted a number of comments and study reservations. Following the discussion, the expert from Turkey volunteered to prepare a revised proposal for consideration at the next GRSG session, taking into account the comments received.
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)”.
32. Referring to ECE/TRANS/WP.29/GRSG/2017/27, the expert from AEGPL recalled the purpose of his proposal to clarify the provisions in UN Regulation No. 67 on the use of non-seamless gas tubes in LPG vehicles. GRSG adopted the document, as amended below, and requested the secretariat to submit it to WP.29 and AC.1 as part (see para. 31 above) of draft Supplement 15 to the 01 series of amendments to UN Regulation No. 67 for consideration at their March 2018 sessions.
Paragraph 2.2., subparagraph (s), amend to read:
“(s) Non-seamless and seamless gas tubes and their couplings;”
New paragraph 17.7.1.2., amend to read:
| “17.7.1.2. | The outer diameter of Class 1 gas tubes made of copper shall not exceed 12 mm with a wall thickness of at least 0.8 mm, gas tubes of Class 1 from steel and stainless steel shall not exceed 25 mm with, for gas services, an appropriate wall thickness.” |
| “17.7.4. | Gas pipes made of a non-metallic material shall comply with the requirements of this Regulation, paragraph 6.7.” |
Annex 15, paragraph 5., replace “Only longitudinal welding” by “Only straight longitudinal welding”.
33. Recalling the discussion on ECE/TRANS/WP.29/GRSG/2017/10 at the previous GRSG session, the expert from AEGPL presented ECE/TRANS/WP.29/GRSG/2017/30 to further clarify the provisions for type approved accessories fitted to LPG containers and to insert an additional indication mark. The expert from Poland raised a study reservation and introduced the obligation to mark the products with the designation of the version, variant and the extension number of the type-approval certificate (GRSG-113-09). Both proposals received a number of comments.
34. Finally, GRSG considered a revised proposal (GRSG-113-36) and adopted ECE/TRANS/WP.29/GRSG/2017/30 as amended below.
Part I, paragraph 4.2., amend to read:
| “4.2. | All equipment shall have …… drawings referred to in paragraph 3.2.2. above. In the case of limited space for the approval mark(s), other means of identification that link it to the approval mark shall be provided.” |
35. The secretariat was requested to submit the proposal to WP.29 and AC.1 as part (see paras. 31 and 32 above) of draft Supplement 15 to the 01 series of amendments to UN Regulation No. 67 for consideration at their March 2018 sessions.
36. The expert from Poland introduced GRSG-113-08 proposing to amend the provisions of Annex 2B on the layout of the communication form and to insert new items for information on the type, variant, version and class of the approved LPG equipment. The document received a number of comments. Following the discussion, GRSG agreed to resume consideration of this subject at its next session in April 2018 on the basis of a revised proposal by Poland.
37. Referring to GRSG-113-10, the expert from Poland also proposed to remove the trade name or trade mark from the definition of a type of LPG container. GRSG noted some comments and general support. The expert from Poland volunteered to review his proposal taking into account the comments received and to submit, in due time, a combined official document for consideration at the next GRSG session.
