ISO 185:2005 PDF

Scope: This International 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 International Standard specifies the characterizing properties of grey cast iron by either a) the tensile strength of separately cast samples, or if agreed by the manufacturer and the purchaser, of cast-on samples or samples cut from a casting (see Table 1), or b) if agreed between the manufacturer and the purchaser, the hardness of the material measured on castings (see Table 2) 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. When specifying a combination of tensile strength and hardness, it is recommended to consult the information in Annex B. This International Standard does not apply to grey cast irons used for pipes and pipe fittings and continuous cast products. This International Standard specifies eight grades of grey cast iron according to the tensile strength (see Table 1) and six grades of grey cast iron according to the Brinell hardness (see Table 2).
