This European Standard specifies requirements for the design, materials, manufacturing and testing of pressure
vessels and pressure vessel parts intended for use with a maximum allowable pressure, PS, equal or less than 100
bar and shell wall thicknesses not exceeding 60 mm, which are constructed of ferritic or austenitic spheroidal
graphite cast iron. The thickness limitation of the shell does not apply to thickness of flanges, reinforcements,
The allowable grades do not include lamellar graphite cast iron grades for ferritic and austenitic grades, which are
explicitly excluded from this European Standard because of low elongation and brittle material behaviour, which
requires the use of different safety factors and a different approach.
NOTE 1 Austenitic spheroidal graphite cast iron grades are principally used for high and low temperature applications and for
their corrosion resistance properties.
NOTE 2 The allowable grades of spheroidal graphite cast iron are listed in Tables 3 and 4. Service conditions are given in
