NBN EN 13835:2012

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].
