UN R110: Proposal for Supplement 1 to the 05 of Amendments
Proposal defines the working pressure for an LNG tank to be the primary relief valve setting (paragraph 4.4.), without stating a minimum value of the said relief valve. If a vehicle has an on-board tank with a primary relief valve that opens at a lower pressure than that at which the filling station is set to stop, the primary relief valve will open during refueling and this is an obvious safety risk.
