scope:

This European Standard specifies requirements for the design and construction of onshore stationary liquefied natural gas (LNG) installations with a total storage capacity between 5 t and 200 t. This standard is not applicable to liquefaction process facilities based on hydrocarbon refrigerants. Larger installations are treated according to EN 1473:1997. If other dangerous substances are present in the facility, the aforementioned storage capacity thresholds may be reduced. The installations to which this standard is applicable include the following: - LNG satellite plants. The LNG may be supplied by road tankers, barge or rail carriers. After storage, LNG is vaporized and sent out to consumers; - LNG gas fuelling stations for vehicles. The installation is limited from the gas inlet or the loading LNG area to the gas outlet or the unloading LNG area. Filling systems are not covered here. For the purposes of clause 4 "Environment Impact" and clause 5 "Safety Plan", this standard applies where LNG storage capacity exceeds the threshold specified in the local regulation. If this value is not available, a threshold of 50 t is recommended. It is recalled that, in any case, local regulations prevail.
