scope:

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 Part 3) [1]. This European Standard does not cover all aspects of: . ausferritic cast irons which are specified in accordance with EN 1564 [2]; . low alloyed ferritic spheroidal cast irons which are specified in accordance with prEN XXX[3]; . EN 13835, austenitic cast irons [4]; . spheroidal graphite cast iron used for pipes, fittings and their joints which are the subject of EN 545, EN 598 and EN 969; . the grades of spheroidal graphite cast iron as specified in EN 545 which may be used for cast iron 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.
