Tanks must meet leak tests performed when equipped with all accessories normally attached to them. It is tested at a relative internal pressure equal to twice the operating overpressure, but in no case less than an overpressure of 30 kPa (0,3 bar).
Any overpressure or any pressure exceeding the working pressure will be automatically compensated by suitable devices (vents, safety valves, etc.). Grilles will be designed to prevent the risk of fire. Especially while the tanks are being filled, any fuel that may leak will not fall on the exhaust system. It will be channeled to the ground.
Tanks must not be located within or on a surface (floor, wall, bulkhead) of the passenger compartment or any other compartment integrated with it. A partition shall be provided to separate the passenger compartment from the tanks. The compartment may include openings (for example, for locating cables) provided that it is arranged so that fuel cannot flow freely from the tank(s) into the passenger compartment or other compartment integrated with it during normal conditions of use.
