Proposal for a new series of amendments to UN Regulation No. 110 to improve the specifications for the installation and inspection of CNG cylinders and of LNG tanks and their accessories. This proposal addresses incidents caused by cylinder corrosion. The proposal aims to reinforce the requirements for adequate cylinder protection and for sufficient access to the cylinder and its accessories to allow regular visual inspection.

Proposal to require, in instances where ogive protective covers are fitted to a cylinder, that the covers be removed before conducting the impact damage (drop) test.

Proposal to harmonize the requirements on Compressed Natural Gas (CNG) and/or Liquefied Natural Gas (LNG) vehicles of UN Regulation No. 110 with those of the international standard ISO 11439:2013.
