GRSG-108-02/Rev.1 | Terms of Reference for a GRSG informal working group on Natural Gas Vehicles (NGV) (revised)
Related discussions
107th GRSG session (30 Sep-3
Oct 2014)
26. Recalling its request at the previous session, GRSG noted the availability of ISO STD 11439:2013 and ISO 6722 (GRSG-107-28) with a condition of limited use by GRSG experts. The expert from NGV Global introduced the terms of references (ToR) for the proposed IWG to revise the provisions of the UN Regulation (GRSG-107-02), including the harmonization of provisions related to private standards. The expert from Germany suggested that the proposed ToR needed improvement and added that he did not support the establishment of an IWG that would revise the UN Regulation without a clear description of tasks. The expert from France made similar comments and raised concerns on the availability of ISO standards. The Chair of GRSG suggested the possible solution of reproducing the part concerned with ISO STD 11439:2013 into Annex 3 of the UN Regulation rather than to reference it. GRSG agreed to resume discussion at its May 2015 session on the basis of a revised proposal tabled by the expert from NGV Global. Interested experts were invited to contact the expert from NGV to complete the revised draft ToR.
45. The expert from NGV Global introduced GRSG-108-02-Rev.1 justifying to withdraw from consideration at this time his initial proposal (GRSG-108-02) for the terms of reference to establish a IWG on Natural Gas Vehicles (NGV) to develop an amendment to UN Regulation No.110. GRSG agreed to resume consideration of this subject at one of its next sessions on the basis of a new proposal taking into account new input from the NGV stakeholders.

22. GRSG considered ECE/TRANS/WP.29/GRSG/2014/27 on introducing a new class of compressed natural gas (CNG) components (Class 6). The proposal received a number of comments from GRSG. The expert from IANGV introduced GRSG-107-38 (superseding GRSG-107-03), for the follow-up discussion. Finally, GRSG adopted ECE/TRANS/WP.29/GRSG/2014/27 as amended by Annex III of the GRSG-107 session report. The secretariat was requested to submit the proposal to the March 2015 sessions of WP.29 and AC.1 as draft Supplement 3 to the 01 series of amendments to UN Regulation No. 110.

107th GRSG session (30 Sep-3

27. The expert from Japan introduced GRSG-107-09 and GRSG-107-37, informing GRSG about the outcome of a “Study group for CNG cylinders” established in Japan for investigation of safety related issues in UN Regulation No. 110. The expert from EC encouraged discussion on this subject. GRSG agreed to resume discussion on this subject at its May 2015 session, awaiting further information provided by the expert from Japan.
33. The expert from Japan introduced GRSG-109-08 (superseding ECE/TRANS/WP.29/GRSG/2015/27) proposing to remove from UN Regulation No. 110 the provisions for welded constructions of compressed natural gas (CNG) cylinders or metal liners, including high-strength steel CNG cylinders. The proposal received a number of comments on the need for performance oriented requirements and the transitional provisions. Instead of adopting the proposal as a new 03 series of amendments, GRSG preferred to defer the adoption by WP.29 of the draft 02 series of amendments to UN Regulation No. 110 (currently on the agenda of the November 2015 session of WP.29 as ECE/TRANS/WP.29/2015/90) to its March 2016 session to insert the amendments proposed by Japan. GRSG endorsed the submission of a new consolidated proposal for the 02 series of amendments as reproduced in GRSG-109-22-Rev.1.
34. In this respect, GRSG adopted the proposed text as reproduced in Annex VI to the report. The secretariat was requested to submit the proposal to WP.29 and AC.1 for consideration at their March 2016 sessions, as a new draft 02 series of amendments to UN Regulation No. 110 (superseding ECE/TRANS/WP.29/2015/90).

24. The expert from the Netherlands introduced ECE/TRANS/WP.29/GRSG/2014/29 to regulate the direction of discharging the pressure relief devices of CNG containers. He explained that the proposal addressed the safety of not only the vehicle occupants but also the surrounding area.

23. The expert from Belgium introduced ECE/TRANS/WP.29/GRSG/2014/28 clarifying the provisions for the periodic inspection of pressure relief valves. The expert from OICA suggested to improve the proposal by adding further instructions on how to conduct the tests. The expert from France raised similar comments and suggested to indicate the exact test that should be conducted either visually or physically. The expert from IANGV argued the lack of empirical evidence for the proposal and suggested a five-year frequency of visual inspection frequency. The expert from Germany stated that the proposal addressed issues beyond of the scope of the type approval procedures. Finally, GRSG agreed to resume discussion on this matter at its May 2015 session.
33. The expert from Belgium presented GRSG-106-15 reflecting the current provisions of UN Regulation No. 110 on the periodic requalification of CNG gas cylinders (Annex 3A) and LNG tanks (Annex 3B). She questioned the differences in the periodicity for the inspection of such cylinders and tanks. Following the discussion, GRSG underlined the need to investigate this subject and agreed to keep GRSG-106-15 on the agenda.

38. On the same subject than that mentioned under para. 35 above (new provisions for “valve control at stop-start”), the expert from CLEPA introduced ECE/TRANS/WP.29/GRSG/2013/26 proposing similar amendments to UN Regulation No. 110. GRSG adopted the document, as reproduced in Annex III of the session report, and requested the secretariat to submit the amendments to WP.29 and AC.1 for consideration at their March 2014 sessions as part (see para. 37 above) of draft Supplement 2 to the 01 series of amendments to UN Regulation No. 110.
32. Recalling the discussion at the previous session of GRSG, the expert from the Netherlands presented GRSG-106-07 proposing new provisions on a directional discharge of the pressure relief devices of GNG containers. GRSG noted a number of comments on the possible location of the containers on the vehicle and questioned the need to also address vehicles with LNG or even hydrogen containers. Following the discussion, GRSG agreed to resume consideration at its next session in October 2014, on the basis of a revised proposal to be submitted by the expert from the Netherlands.
41. The expert from the Netherlands introduced ECE/TRANS/WP.29/GRSG/2015/6 proposing new provisions on a directional discharge of the pressure relief devices for Compressed Natural Gas (CNG) containers. The expert from Germany presented GRSG-108-08 proposing a number of improvements to the proposed text. Following the discussion, GRSG noted a general support on the final proposal as reflected in GRSG-108-08-Rev.2.
42. GRSG adopted ECE/TRANS/WP.29/GRSG/2015/6 as amended by Annex IV to this report. The secretariat was requested to submit the adopted proposal to WP.29 and AC.1 for consideration at their November 2015 sessions, as draft 02 series of amendments to UN Regulation No. 110.
