Spheroidal graphite cast iron -- Classification
This standard has been revised by ISO 1083:2004.
This second edition cancels and replaces the first edition (ISO 1083:1976), in which only six grades of spheroidal graphite cast iron were defined. Defines nine grades of spheroidal graphite cast iron and their classification in two distinct categories (separately cast test samples and cast-on test samples, respectively). An annex gives a classification as a function of hardness.
