DANSK DS/EN 1563 PDF

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 prEN 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.
