Phạm vi áp dụng / Scope of standard

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 mainly 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 [3] and EN 1559-3 [4])

This European Standard does not cover:

- ausferritic spheroidal graphite cast irons which are specified in EN 1564 [5];

- low alloyed ferritic spheroidal graphite cast irons which are specified in EN 16124 [6];

- continuous cast iron bars which are specified in EN 16482 [7];

- austenitic cast irons which are specified in EN 13835 [8];

- spheroidal graphite cast irons used for pipes, fittings and their joints which are the subject of EN 545 [9], EN 598 [10] and EN 969 [11];

- the grades of spheroidal graphite cast irons 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.
