Organization: DIN

Status: active
Page Count: 35
ICS Code (Irons): 77.080.10
scope:

This European Standard specifies the properties of unalloyed and low-alloyed grey cast irons used for castings, which have been manufactured in sand moulds or in moulds with comparable thermal behaviour.

This European Standard specifies the characterizing properties of grey cast irons by either

a) the tensile strength of cast samples, or

b) the hardness measured on the castings or on a cast-on knob.

If agreed by the manufacturer and the purchaser, the combination of both tensile strength from option a) and hardness from option b) may be specified.

This European Standard specifies six grades of grey cast iron by a classification based on tensile strength measured on machined test pieces prepared from cast samples (see Table 1) and six grades of grey cast iron by a classification based on Brinell hardness (see Table 2).

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 apply to grey cast irons used for pipes and fittings according to EN 877 [5].
