This European Standard specifies the grades and corresponding requirements for austenitic cast irons. These requirements are specified in terms of:
— graphite form and metal structure: either flake or spheroidal graphite in an austenitic matrix;
— chemical composition: as given for each of the grades;
— mechanical properties measured on machined test pieces prepared from cast samples.
This standard does not cover technical delivery conditions for iron castings, see EN 1559-1 [1] and EN 1559-3 [2].
