3. Mr. Dijkhof indicated that the comments from Germany probably are due to different fill pressures used in Germany and that higher fill pressures may result in boil off.

35. The expert from Germany withdrew GRSG-105-31. He presented GRSG-106-27 requiring the mandatory exterior protection of gas cylinders instead of leaving the decision up to the manufacturer. The experts from France and OICA preferred to adopt such mandatory provisions together with a set of transitional provisions. GRSG agreed to resume consideration at its next session in October 2014, on the basis of a revised proposal by the expert from Germany.

41. The expert from Germany announced to prepare, for the next session of GRSG, a set of draft amendments to UN Regulation No. 110 preventing the LNG container from being overfilled and requiring the installed of a safety system against flooding by LNG (GRSG-105-31). GRSG noted that these issues had already been discussed by the LNG Task Force.

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.
