[Postponed until June 2016 session in order to integrate the contents with additional provisions under development within the GRSG.]

31. The GRSG chair recalled that GRSG had already adopted at its previous session in May 2015 a new 02 series of amendments proposing provisions on a directional discharge of the pressure relief devices of CNG containers (submitted as ECE/TRANS/WP.29/2015/90 to the November 2015 session of WP.29). He added that GRSG had just adopted another amendment removing the provisions on welded cylinders and raising again the stringency of Regulation No. 110. Instead of adopting that amendment as a further new series of amendments, GRSG had agreed to remove ECE/TRANS/WP.29/2015/90 from the WP.29 agenda in November 2015 and to submit a new draft 02 series of amendments to UN Regulation No. 110, incorporating both proposals (directional discharge and removal of welded cylinders) for consideration at the March 2016 session of WP.29.

61. The consideration of ECE/TRANS/WP.29/2015/90 tabled under agenda item 4.7.9 was deferred to the March 2016 session of WP.29 (see para. 31 above).
