BS EN 1563:2018 pdf download.Founding – Spheroidal graphite cast irons
1 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 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:
一ausferritic spheroidal graphite cast irons which are specified in EN 1564 [5];
一low alloyed ferritic spheroidal graphite cast irons which are specified in EN 16124 [6];
一continuous cast iron bars which are specified in EN 16482 [7];
一austenitic cast irons which are specified in EN 13835 [8];
一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.

7 Requirements
7.1 General
The property values apply to spheroidal graphite cast irons cast in sand moulds or moulds of comparable thermal behaviour. Subject to amendments to be agreed upon in the order, they can apply to castings obtained by alternative methods. The material designation is based on the minimum mechanical properties obtained in cast samples with a thickness or diameter of 25 mm. The designation is irrespective of the type of cast sample. Mechanical properties are wall thickness dependant as shown in Tables1, 2 and 3. For relevant wall thicknesses more than 200 mm, the manufacturer and the purchaser shall agree on the minimum values to be obtained and the type and size of the cast sample. Tensile testing requires sound test pieces in order to guarantee pure uni-axial stress during the test.
