This International Standard specifies one method of classifying the microstructure of graphite in cast irons by comparative visual analysis. The purpose of this standard is to provide in formation about the method of graphite classification. It is not intended to give information on the suitability of cast iron types and grades for any particular application. The particular material grade is specified by results from tensile tests or hardness testing, and in the case of austenitic cast irons, by their chemical composition. The interpretation of graphite form and size does not allow a statistically valid statement on the fulfilment of the requirements specified in the relevant material standard. The structure of the ferrous matrix (ferrite, pearlite, free cementite) has a significant effect on the material properties. Such an interpretation is not the purpose of this International Standard.
