This European Standard specifies the design, testing and marking requirements for caps and plugs used to form a pressure tight seal with liquefied petroleum gas (LPG) cylinder valves and pressure vessel valves. Sealing caps and plugs provide an additional seal for self-closing and manually operated valves. Dust caps and tamper evident seals that do not form an additional seal as part of their design are excluded from the scope of this European Standard.Cylinder valve caps and plugs may be used with valves for liquid and vapour manufactured in accordance with EN ISO 14245 and EN ISO 15995.Pressure vessel valve caps and plugs may be used with valves for liquid and vapour manufactured in accordance with EN 13175. Occasional liquid withdrawal valve caps and plugs are excluded from the scope of this European Standard. Reusable and single use sealing caps and plugs are included in this European Standard.This European Standard does not exclude the use of other designs that provide an equivalent level of safety.NOTEThe term "pressure vessel" does not include LPG tank vehicles, also called "road tankers", in CEN/TC 286 standards.
