1 Scope <p>This document specifies the properties of unalloyed and low-alloyed grey cast irons used for castings that have been manufactured in sand moulds or in moulds with comparable thermal behaviour.</p>
<p>This document specifies the characterizing properties of grey cast irons by any of the following:</p>
<p>a) the tensile strength of cast samples;</p>
<p>b) if agreed by the manufacturer and the purchaser, the tensile strength of samples cut from a casting;</p>
<p>c) if agreed between the manufacturer and the purchaser, the hardness of the material determined on castings or on a cast-on knob.</p>
<p>If agreed by the manufacturer and the purchaser, the combination of tensile strength from option a) or option b) and plus hardness from option c) can be specified. Information on specifying a combination of tensile strength and hardness is given in Annex B.</p>
<p>This document specifies eight grades of grey cast iron according to tensile strength (see Table 1) and six grades of grey cast iron according to Brinell hardness (see Table 2).</p>
<p>This document does not apply to grey cast irons used for pipes and pipe fittings and continuous cast products.</p>
<p>This document does not cover technical delivery conditions for grey iron castings.</p>
<p>NOTE General information on the engineering properties of grey cast irons is provided in ISO/TR 10809-1.</p>
