115th GRSG session (9-12 Oct 2018)
GRSG-115-06

37. Recalling the discussion of GRSG at its previous session, the expert from Italy introduced ECE/TRANS/WP.29/GRSG/2018/16 to amend Annex 3A of the Regulation on the test requirements for Compressed Natural Gas (CNG) cylinders to avoid structural failures during their service life. The expert from NGV Global proposed some further clarifications (GRSG-115-06) and a new definition on “certified cylinder”. The proposals received general support.

39. The expert from OICA introduced GRSG-115-18-Rev.2 amending the Regulation with respect to the inspection requirements for the periodic requalification of CNG cylinders to avoid structural failures during their service life. Finally, GRSG adopted ECE/TRANS/WP.29/GRSG/2018/16, ECE/TRANS/WP.29/GRSG/2018/13 and GRSG-115-18-Rev.2 as reproduced in Annex III to this report. The secretariat was requested to submit the proposals to WP.29 and AC.1 as draft Supplement 2 to the 03 series of amendments to UN Regulation No. 110 for consideration at their March 2019 sessions.

113th GRSG session (10-13 Oct 2017)
GRSG/2017/29

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.
