BS EN 1563:2011 pdf download – Founding — Spheroidal graphite cast irons
This European Standard defines the grades and the corresponding requirements for spheroidal graphite castirons.
This European Standard specifies 2 groups of spheroidal graphite cast iron grades by a classification basedon mechanical properties measured on machined test pieces prepared from cast samples. The first groupdeals 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] andEN 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 []and EN 969 [10];
the grades of spheroidal graphite cast iron as specified in EN 545 which are used for products such asindustrial valves, non industrial manually operated shut-off valves and flanges and their joints,which arethe subject of the applicable European product standards.

3Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
spheroidal graphite cast iron
cast material，iron，carbon and silicon-based,the carbon being present mainly in the form of spheroidalgraphite particles
NOTE Spheroidal graphite cast iron is also known as ductile iron, and less commonly as nodular iron.
3.2
ferritic to pearlitic spheroidal graphite cast iron
spheroidal graphite cast iron with a matrix containing ferrite or pearlite or a combination of both
NOTE Pearlite can be partially or totally replaced by bainite or tempered martensite in grades having higher strength
3.3
solid-solution strengthened ferritic spheroidal graphite cast iron
spheroidal graphite cast iron with a matrix mainly consisting of ferrite, solution strengthened mainly by silicon
3.4
graphite spheroidizing treatment
operation that brings the liquid iron into contact with a substance to produce graphite in the predominantly spheroidal (nodular) form during solidification
NOTE This operation is often followed by a second one called inoculation.
3.5
cast sample
quantity of material cast to represent the cast material, including separately cast sample, side by side cast sample and cast-on sample
3.6
separately cast sample
sample cast in a separate sand mould under representative manufacturing conditions and material grade
3.7
side-by-side cast sample
sample cast in the mould alongside the casting, with a joint running system
3.8
cast-on sample
sample attached directly to the casting
3.9
relevant wall thickness
wall thickness representative of the casting, defined for the determination of the size of the cast samples to which the mechanical properties apply
4 Designation
The material shall be designated either by symbol or by number as given in Tables 1, 2 or 3.
In the case of samples cut from the casting the letter C is added at the end of the designation by symbol.
NOTE The comparison of EN 1563 grade designations with the grades from the ISO standard for spheroidal graphite cast iron, ISO 1083:2004 [11], is given in Annex H.
5 Order information
The following information shall be supplied by the purchaser:
a) the number of this European Standard;
b) the designation of the material;
c) the relevant wall thickness;
d) any special requirements.
