DIN EN 13445-6:2015-12

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 to 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, bosses, etcetera. 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. The responsible German committee is Working Committee NA 012-00-05 AA "Unbefeuerte Druckbehälter" ("Unfired pressure vessels") at DIN Standards Committee Chemical Apparatus Engineering (FNCA).
