23. The expert from Germany introduced GRSG-114-08 on the recent meeting of the task force on gas-fuelled vehicle regulations held in Cologne (Germany) on 6 and 7 February 2018. He added that progress had been good on UN Regulation No. 110, but the amendments to UN Regulation No. 67 were still under considerations. 25. The expert from Germany recalled the outcome of the task force (para. 23 above) on ECE/TRANS/WP.29/GRSG/2017/16 and presented GRSG-114-09 proposing amendments to the Regulation. GRSG noted general support and some comments. Finally, GRSG considered a revised proposal (GRSG-114-09-Rev.1) and adopted ECE/TRANS/WP.29/GRSG/2017/16 as reproduced in Annex V to the session report. The secretariat was requested to submit the proposal to WP.29 and AC.1 as draft 02 series of amendments to UN Regulation No. 67 for consideration at their November 2018 sessions. 28. The expert from Germany introduced GRSG-114-10 on the outcome of the task force on ECE/TRANS/WP.29/GRSG/2017/17 which was on improving the provisions for installing and inspecting Compressed Natural Gas (CNG) cylinders or Liquefied Natural Gas (LNG) tanks and their accessories. The expert from Italy preferred a more accurate inspection of such containers without the removal of structural parts (GRSG-114-19). After discussion, GRSG agreed to add design requirements that allow easy periodical technical inspections. The expert from the Netherlands requested that container manufacturers provide more detailed recommendations for periodical technical inspections and for periodic requalification tests, and requested that these recommendations be stored and made available for all inspections. 30. Finally, GRSG considered a revised proposal (GRSG-114-10-Rev.1) and adopted ECE/TRANS/WP.29/GRSG/2017/17 as reproduced below. The secretariat was requested to submit the proposal to WP.29 and AC.1 as draft Supplement 1 to the 03 series of amendments to UN Regulation No. 110 for consideration at their November 2018 sessions. Insert a new paragraph 18.1.6.1., to read:
31. The expert from Italy, in reference to ECE/TRANS/WP.29/GRSG/2017/29, proposed to amend Annex 3A of the Regulation, i.e. the test requirements for the periodic requalification of CNG cylinders to avoid structural failures during their service life (GRSG-114-32), including new provisions for a mandatory impact damage test for all cylinders without the use of shoulder pads. GRSG welcomed the specific test reports provided by Italy on CNG4 cylinders (GRSG-114-07, GRSG-114-14, GRSG-114-15). GRSG noted concerns and comments. Finally, GRSG agreed to refer it to the task force and to resume consideration of this subject at its next session on the basis of a revised official document. |
