This standard applies to a Storage plant, gas station and process plant for hydrogen, methane and ethene (ethylene), if the sum of the volumetric capacities (litres) of the transportable gas containers simultaneously present exceeds 501.
When calculating the volumetric capacity in the case of gas mixtures, only the proportion of the volume containing the gases listed above is taken into account.
Standard SFS 3179 shall be applied to a methane piping system for which the maximum allovvable vvorking pressure does not exceed 4 bar (0,4 MPa).
