Proposal to
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.
