BS EN 1563:2011

Founding. Spheroidal graphite cast irons (British 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 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 all aspects of:
- 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];
- austenitic cast irons which are specified in EN 13835 [7];
- spheroidal graphite cast irons used for pipes, fittings and their joints which are the subject of EN 545 [8], EN 598 [9] 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.
