ISO DIS 1083

Description / Abstract: This document defines the grades and the corresponding requirements for spheroidal graphite cast irons.

This document specifies two groups of spheroidal graphite cast iron grades by a classification based on mechanical properties measured on machined test pieces prepared from cast samples. The first group deals mainly with ferritic to pearlitic grades. The second group deals with solid-solution strengthened ferritic grades.

This document also specifies a classification as a function of hardness.

This document does not apply to:

• 
  
  spheroidal graphite cast iron used for pipes, fittings and accessories which are specified in accordance with ISO 2531 and ISO 7186;

• 
  
  highly alloyed (austenitic) spheroidal cast irons which are specified in accordance with ISO 2892;

• 
  
  ausferritic cast irons which are specified in accordance with ISO 17804.
