European foreword
This document (prEN 16482:2022) has been prepared by Technical Committee CEN/TC 190 “Foundry
technology”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 16482:2014.
The following modifications were implemented in this new version:
— new normative references;
— new reference to ASTM A536-84 (2009) Standard Specification for Ductile Iron Castings in the text
and Bibliography;
— modification of Table 2 “Tensile properties of continuous cast spheroidal graphite cast iron bars”,
where 2 Grades were modified to fulfill requirements also of ASTM A536-84 (2009): EN-GJS-400-
18C;
— new Table 4 “Minimum impact energy values measured on V-notched test pieces machined from
cast samples for ferritic grades of the ferritic to pearlitic group” in 7.4 (imported from
EN 1563:2019);
— new Table 5 “Straightness of continuous cast bars” in 7.7;
— new subclause 7.8 “Ultrasonic Testing”;
— new Figure 1 “Dimensions of grey cast iron tensile test pieces”;
— new Figure 2 “Dimensions of spheroidal graphite cast iron tensile test pieces”;
— modification of Table A.1 “Guidance values for Brinell hardness”;
— modification of Table B.2 “Machining allowances for continuous cast iron bars”;
— modification of Table D.2 “Examples of mechanical properties measured on continuous cast iron
bars with a diameter of 160 mm”.

Introduction
The European Standards EN 1561:2011 and EN 1563:2018 classify grey cast irons and spheroidal
graphite cast irons respectively, which are cast in sand moulds or moulds of comparable thermal
behaviour.
This document classifies grey cast iron and spheroidal graphite cast iron bars, which are produced by
the continuous casting process.
Due to the high cooling rate during solidification and further cooling, both graphite and matrix structure
differ from those obtained by sand casting and consequently the mechanical properties in relation to
section thickness [8], [9].
The mechanical properties of continuous cast iron bars are evaluated on machined test pieces prepared
from samples cut from the bars.
However, for many applications, tensile strength or hardness are not the only interesting or
determining properties. Other mechanical or physical properties can be decisive for the use of grey cast
iron or spheroidal graphite cast iron, for example: thermal capacity, thermal diffusivity, damping
capacity, thermo-cycle fatigue and toughness.
Additional technical data for grey cast irons is given in EN 1561:2011 and for spheroidal graphite cast
irons in EN 1563:2018 and Annex D of this document.

1 Scope
This document defines the grades of grey cast iron and spheroidal graphite cast iron bars, which have
been produced by the continuous casting process.
This document specifies the characterizing properties of grey cast iron bars by either:
a) the tensile strength measured on machined test pieces prepared from samples cut from the bars, or
b) the hardness measured on the bars.
If agreed by the manufacturer and the purchaser, the combination of both tensile strength from option
a) and hardness from option b) can be specified.
This document specifies the characterizing properties of spheroidal graphite cast iron bars by the
tensile strength measured on machined test pieces prepared from samples cut from the bars.
This document specifies 4 grades of grey cast iron and 14 grades of spheroidal graphite cast iron by a
classification based on tensile strength and 4 grades of grey cast iron by a classification based on Brinell
hardness.
This document specifies also the straightness of the bars.
This document does not cover technical delivery conditions for iron castings (see EN 1559-1:2011 and
EN 1559-3:2011).
