3.5.3. | Working Party on General Safety Provisions (GRSG) (109th session, 29 September-2 October 2015)

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.

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.
