24. The expert from the Netherlands presented GRSG-111-19 superseding ECE/TRANS/WP.29/GRSG/2016/7 and amending the provisions of UN Regulation No. 67 on LPG vehicles to allow Class 0/I hoses with couplings using gas tubes other than seamless material. The document received a number of comments. GRSG noted study reservations by the experts from Germany and AEGPL. GRSG reviewed the proposal as reflected in GRSG-111-19-Rev.1 and agreed to resume consideration of this subject at its next session in April 2017. The secretariat was requested to circulate GRSG-111-19-Rev.1 with an official symbol. |
Document Title: Proposal for Supplement 15 to the 01 series of amendments to Regulation No. 67 |
Document Reference Number: GRSG-112-19 |
Description: Proposal to allow for the approval of systems using non-seamless double and single wall tubes subject to testing for high pressure and high resistance to pressure pulses. The proposal would also add general test requirements for LPG fuel lines and couplings based on ISO Standard 15500 for compressed natural gas equipment. |

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. |
Document Title: Proposal for amendments to Regulation No. 67 |
Document Reference Number: GRSG/2016/7 |
Description: Proposal to allow the use of Class 0 hoses with couplings using sealing technologies other than those with a 45° cone. Currently, non-seamless double and single wall tubes are used in brake and fuel tubing applications, allowing for the use of a variety of end forms and coupling techniques. Provided the tubing can withstand the applicable tests according to Annex 15, Table 1, such configurations should be permitted under UN R67 in order to remove an unwarranted design restriction. |

26. Recalling the purpose of ECE/TRANS/WP.29/GRSG/2016/7, the expert from the Netherlands presented GRSG-110-25 amending the provisions of UN Regulation No. 67 on LPG vehicles to allow Class 0/I hoses with couplings using gas tubes other than seamless material. GRSG noted a number of comments on the need for detailed testing specifications for type approval purposes and for clarification of the responsibilities. The Chair of GRSG invited all experts to send their written comments to the expert from the Netherlands. GRSG agreed to resume consideration of this subject at its next session in October 2016 on the basis of an updated official document by the Netherlands taking into account the comments received. 24. The expert from the Netherlands presented GRSG-111-19 superseding ECE/TRANS/WP.29/GRSG/2016/7 and amending the provisions of UN Regulation No. 67 on LPG vehicles to allow Class 0/I hoses with couplings using gas tubes other than seamless material. The document received a number of comments. GRSG noted study reservations by the experts from Germany and AEGPL.

Document Title: Proposal for amendments to Regulation No. 110 |
Document Reference Number: GRSG/2016/8 |
Description: Proposal to allow the use of Class 0 hoses with couplings using sealing technologies other than those with a 45° cone. Currently, non-seamless double and single wall tubes are used in brake and fuel tubing applications, allowing for the use of a variety of end forms and coupling techniques. Provided the hose assembly can withstand the impulse test of paragraph 1.7. and the tests of Annexes 5A (overpressure test) and 5B (external leakage test), such configurations should be permitted under UN R67 in order to remove an unwarranted design restriction. In cases where a soft seal body (e.g. O-ring) is used, the compatibility of the material with use conditions must be demonstrated by testing according to Annexes 5D (CNG/LNG compatibility test), Annex 5F (resistance to dry heat) and Annex 5G (ozone aging). |

35. The expert from the Netherlands introduced GRSG-110-26 (superseding ECE/TRANS/WP.29/GRSG/2016/8) proposing an amendment to UN Regulation No. 110 to allow Class 0 hoses with couplings using sealing technologies other than those with a 45° cone and, thus, to avoid design restrictive requirements. The proposal received a number of comments. 36. GRSG adopted the proposal as reproduced below and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2016 sessions, as part (see para. 32 above) of draft Supplement 5 to the 01 series of amendments to UN Regulation No. 110. Annex 4B, paragraph 1.6.2.2., amend to read: “1.6.2.2. The interface type for the hose coupling shall be: (a) sealing cone of swivel-nut type of the type with a half vertical angle of 45°, or In the case of an interface type using a soft seal body (e.g. O-ring), the type of material chosen shall be tested in accordance with Annexes 5D, 5F and 5G. Couplings shall have complementary counterparts." |
29. The expert from ISO presented GRSG-109-14 on the progress of work within the ISO working group on refueling connector and fuel components for vehicles propelled by Liquefied Natural Gas (LNG). He underlined the request from original equipment manufacturers to update UN Regulation No. 67 with respect to LPG fuel lines and welding requirements.
32. Referring to his presentation (GRSG-109-14) given under agenda item 8 (para. 28 above), the expert from ISO volunteered to submit for the next GRSG session an official document proposing to amend the provisions of Annex 4B of UN Regulation No. 110, including the correction of some errors in Annexes 4A and 4H.
