Annotation of standard text ČSN EN 1561 (420953):
This document 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. NOTE - This document can also be applicable to grey cast irons cast in permanent moulds, provided the related cast samples are poured under the same conditions as the castings. This document specifies the characterizing properties of grey cast irons by either: a) the tensile strength of cast samples, b) if agreed by the manufacturer and the purchaser, the tensile strength of samples cut from a casting, c) the hardness determined 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 c) can be specified. This document specifies five grades of grey cast iron by a classification based on tensile strength determined 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 document does not cover technical delivery conditions for iron castings; see EN 1559-1 and EN 1559-3. This document does not apply to grey cast irons used for pipes and fittings which are covered by to EN 877 [1]
