39、is a stand-alone document and may be used for pressure equipment with certain restrictions and limitations. NOTE For the design and fabrication of cast iron pressure equipment standards with higher elongations and ductility, see EN 13445-6:2014.“ Attention is drawn to the references to !EN 13445-6:2
40、014“for design and fabrication according to specific grades of material standards !EN 1563:2011“and !EN 13835:2012“which are found in some clauses of this standard, EN 15776. Requirements for the design, material, manufacturing and testing of pressure vessels and pressure vessel parts made from ferr
41、itic or austenitic spheroidal graphite cast iron grades with an elongation after fracture higher than 15 % are given in !EN 13445-6:2014“. Cast iron with elongation after fracture equal or less than 15 % may only be used for pressure equipment when operational and technical advantages are dictating
42、its use instead of the cast iron grades given in !EN 13445-6:2014“with elongation after fracture higher than 15 %.
