29. The expert from France proposed incorporating new provisions concerning refrigeration systems for cooling the cargo compartment which are connected to the compressed natural gas (CNG) and/or liquefied natural gas (LNG) system (ECE/TRANS/WP.29/GRSG/2016/16). The expert from Japan raised concerns about risks of increased filling cycles of CNG cylinders due to a higher filling frequency. He suggested supplementing the proposed provisions with additional test conditions to not exceed the maximum number of filling cycles of CNG cylinders (GRSG-111-18). A number of experts were of the opinion that the number of filling cycles of CNG cylinders specified in the test requirements of UN Regulation No. 110 would be sufficient to cover the higher filling frequencies. GRSG did not support the additional test conditions proposed by Japan.

30. GRSG adopted ECE/TRANS/WP.29/GRSG/2016/16 as amended below and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their March 2017 sessions, as draft Supplement 6 to the 01 series of amendments to UN Regulation No. 110.

Paragraph 18.1.7.1., replace “compartiment des marchandises” by “compartiment de chargement”.
Paragraph 18.5.1.3., subparagraphs (b) and (c), replace “compartiment des marchandises” by “compartiment de chargement” and “contrôle électronique” by “contrôle électronique GNC/GNL” (two times).

39. The expert from France presented GRSG-110-23 introducing new provisions for the use of natural gas refrigeration systems to vehicles propelled by natural gas (CNG or LNG). GRSG noted general support on the proposal and agreed to resume consideration of this subject at its next session in October 2016. For that purpose, the secretariat was requested to circulate GRSG-110-23 with an official symbol.
