31. The expert from Italy, in reference to ECE/TRANS/WP.29/GRSG/2017/29, proposed to amend Annex 3A of the Regulation, i.e. the test requirements for the periodic requalification of CNG cylinders to avoid structural failures during their service life (GRSG-114-32), including new provisions for a mandatory impact damage test for all cylinders without the use of shoulder pads. GRSG welcomed the specific test reports provided by Italy on CNG4 cylinders (GRSG-114-07, GRSG-114-14, GRSG-114-15). GRSG noted concerns and comments. Finally, GRSG agreed to refer it to the task force and to resume consideration of this subject at its next session on the basis of a revised official document.
