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. |
Document Title: Proposal for amendments to Regulation No. 67 |
Document Reference Number: GRSG-110-25 |
Description: Proposal of corrections to document GRSG/2016/7. The wording of the original proposal opens the possible interpretation that the regulation allows materials other than copper, stainless steel, or steel with corrosion-resistant coatings for gas tubes. The intention of the proposal was only to allow for “non-seamless” gas tubing. The original proposal is therefore modified to allow Class 0/I hoses with couplings using gas tubes of other than seamless material. |

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. |
Document Title: Updated proposal for amendments to UN Regulation No. 67 |
Document Reference Number: GRSG-111-19/Rev.1 |
Description: Proposal, as modified pursuant to discussions during the October 2016 GRSG session, to amend the provisions of UN R67 (R67) in order to enable the approval of non-seamless double and single wall gas tubes provided they can withstand the applicable tests according to Annex 15. |

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 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. |
