This European Standard defines the grades and the corresponding requirements for spheroidal graphite cast irons.This European Standard specifies 2 groups of spheroidal graphite cast iron grades by a classification based on mechanical properties measured on machined test pieces prepared from cast samples. The first group deals with ferritic to pearlitic grades. The second group deals with solid-solution strengthened ferritic grades.This European Standard does not cover technical delivery conditions for iron castings (see EN 1559-1 and EN 1559-3).This European Standard does not cover all aspects of: ausferritic spheroidal graphite cast irons which are specified in EN 1564; low alloyed ferritic spheroidal graphite cast irons which are specified in EN 16124; austenitic cast irons which are specified in EN 13835; spheroidal graphite cast irons used for pipes, fittings and their joints which are the subject of EN 545, EN 598 and EN 969[10]; the grades of spheroidal graphite cast iron as specified in EN 545 which are used for products such as industrial valves, non industrial manually operated shut-off valves and flanges and their joints, which are the subject of the applicable European product standards.
