適用范圍：This part of ISO 945 specifies a method of classifying the microstructure of graphite in cast irons bycomparative visual analysis.The purpose of this part of ISO 945 is to provide information about the method of graphite classification. It isnot 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 ofaustenitic cast irons, by their chemical composition. The interpretation of graphite form and size does notallow a statistically valid statement on the fulfilment of the requirements specified in the relevant materialstandard. The structure of the metallic matrix (e.g. ferrite, pearlite) has a significant effect on the materialproperties. Such an interpretation is not the purpose of this part of ISO 945.
