38. The expert from ISO introduced GRSG-113-02 and GRSG-113-37 justifying the alignment of the provisions in the UN Regulation with those in the latest version of ISO 11439:2013 (as proposed in ECE/TRANS/WP.29/GRSG/2017/31). The expert from OICA expressed his preference to adopt the proposal as a new series of amendments and suggested inserting transitional provisions (GRSG-113-21). GRSG agreed on the need to insert transitional provisions and to replace the dynamic references to international standards by static ones. Following the discussion, the expert from ISO presented GRSG-113-38 taking into account the comments received. GRSG considered the document in detail and adopted the proposal as reproduced in Annex IV (based on GRSG-113-38-Rev.1). The secretariat was requested to submit it to WP.29 and AC.1, as a new draft 03 series of amendments to UN Regulation No. 110, for consideration at their March 2018 sessions. |

39. The expert from Germany introduced ECE/TRANS/WP.29/GRSG/2017/17 to improve the specifications for the installation and inspection of Compressed Natural Gas (CNG) cylinders or of Liquefied Natural Gas (LNG) tanks and their accessories. GRSG welcomed the proposal and noted that WP.29 and the Administrative Committee of the 1997 Agreement were expected to consider and adopt ECE/TRANS/WP.29/2017/134 on a new UN Rule on Periodical Technical Inspections of motor vehicles using CNG and/or LNG in their propulsion system. The proposal from Germany received a number of comments, especially on the need to align the recommendations for the periodical technical inspections of such vehicles with the specifications for the re-qualification of the CNG cylinders or LNG tanks. GRSG noted the comments received by the experts from NGV Global (GRSG-113-03) and OICA (GRSG-113-20). |

40. The expert from Italy proposed to amend in Annex 3A of the Regulation the test requirements for the periodic requalification of CNG cylinders to avoid structural failures during their service life (ECE/TRANS/WP.29/GRSG/2017/29). The expert from the Netherlands raised his concern on the access by inspection centres to detailed provisions for the inspection of such cylinders. Thus, he underlined the need that cylinder manufacturers should make available cylinder inspection manuals. GRSG welcomed the offer by Germany to take the lead of a Task Force to review ECE/TRANS/WP.29/GRSG/2017/17 and ECE/TRANS/WP.29/GRSG/2017/29. It was agreed to also involve the International Motor Vehicle Inspection Committee (CITA) in the discussion and to resume consideration of this subject at its next GRSG session in April 2018. |

41. The expert from the Netherlands presented GRSG-113-24 and GRSG-113-25 justifying the need to introduce in the Regulation new requirements for components used in LNG/CNG systems such as the “CNG accumulator” and the “CNG compressor”. GRSG noted general support on the proposals. The Chair invited all GRSG experts to send their comments, in due time, to the expert from the Netherlands. GRSG agreed to resume consideration of this subject at its next session on the basis of an official document, prepared by the Netherlands, taking into account the comments received. |

42. The expert from the Netherlands introduced GRSG-113-26 proposing to correct and clarify the references to Annex 5Q in UN Regulation No. 110. GRSG welcomed the proposal and invited the expert from the Netherlands to prepare an official document for consideration at the next session of GRSG in April 2018. |

43. The expert from the NGV Global proposed to correct Table 6.4. on the cylinder design qualification tests (GRSG-113-06). GRSG noted general support on the proposal and agreed to take a final position on this subject at its next session. The secretariat was requested to circulate GRSG-113-06 with an official symbol. |
