scope:

This European Standard defines grades and the corresponding requirements for malleable cast irons. This European standard specifies five grades of whiteheart malleable cast iron and nine grades of blackheart malleable cast iron, based on mechanical properties measured on cast samples (which are test pieces). This European Standard specifies Brinell hardness values determined only when these values are requested by the purchaser. This European Standard does not cover technical delivery conditions for malleable cast iron castings. Reference should be made to EN 1559-1 [3] and EN 1559-3 [4]. This European Standard does not cover chemical composition, except phosphorus (see Clause 6). Grade EN-GJMB-300-6 (5.4100) malleable cast iron shall not be used for any pressure application, e.g. also pressure applications not covered by the Pressure Equipment Directive 2014/68/EU.
