UN R110: Proposal for amendments

115th GRSG session (9-12 Oct 2018)

Status: Superseded

Submitted by Italy

Proposal to require, in instances where ogive protective covers are fitted to a cylinder, that the covers be removed before conducting the impact damage (drop) test.

Discussions and Outcomes

177th WP.29 session (11-15 Mar 2019)

Agenda item 4.8.6. | Proposal for Supplement 2 to the 03 series of amendments to UN Regulation No. 110 (CNG and LNG vehicles)

Agenda item 4.8. | Consideration of draft amendments to existing UN Regulations submitted by GRSG

WP.29/2019/13

103. The World Forum considered the draft amendments under agenda items 4.8.1 to 4.8.8 and recommended their submission to AC.1 for voting, subject to the following corrections:

104. For agenda item 4.8.6, document ECE/TRANS/WP.29/2019/13, para. 6.12, the last sentence “Manufacturers are advised …… Appendix H to this annex.” shall be deleted.

105. The Chair of GRSG presented the amendment proposal in ECE/TRANS/WP.29/2019/16 under agenda item 4.8.9, to amend UN Regulation No. 110 with the following correction in annex 1A, add: “Items 1.2.4.5.15.4. to 1.2.4.5.15.6., shall be deleted.”. The World Forum recommended their submission to AC.1 for voting.

This proposal (WP.29/2019/13), as amended by para. 104 of the 177th session report, was adopted by the World Forum. Thirty-six Contracting Parties out of the 50 applying UN R110 were present for the vote by AC.1. Thirty-six voted in favor with zero against and zero abstaining.

115th GRSG session (9-12 Oct 2018)

Agenda item 9. (b) | UN Regulation No. 110 (CNG and LNG vehicles)

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)

Agenda item 6. (b) | Amendments to gas-fuelled vehicle regulations: Regulation No. 110 (CNG and LNG vehicles

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.
