This document defines the grades and the corresponding requirements for ausferritic spheroidal graphite cast irons.<\/p>\n

This document specifies five grades of ausferritic spheroidal graphite cast iron by a classification based on mechanical properties determined on machined test pieces prepared from:<\/p>\n

    \n
  1. \n

    separately cast samples, side-by-side cast or cast-on samples;<\/p>\n<\/li>\n

  2. \n

    samples cut from a casting.<\/p>\n<\/li>\n<\/ol>\n

    This document also specifies two grades by a classification as a function of hardness.<\/p>\n
