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”. 29.
