标准范围

ISO 945-1:2008规定了通过对比目视分析对铸铁中石墨微观结构进行分类的方法。ISO 945本部分的目的是提供有关石墨分类方法的信息。其目的不是提供铸铁类型和等级适用于任何特定应用的信息。特定材料等级由拉伸试验或硬度试验的结果以及奥氏体铸铁的化学成分规定。对石墨形状和尺寸的解释不允许对满足相关材料标准中规定的要求做出统计上有效的声明。金属基体（如铁素体、珠光体）的结构对材料性能有显著影响。这种解释不是ISO 945本部分的目的。

ISO 945-1:2008 specifies a method of classifying the microstructure of graphite in cast irons by comparative visual analysis.The purpose of this part of ISO 945 is to provide information 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 metallic matrix (e.g. ferrite, pearlite) has a significant effect on the material properties. Such an interpretation is not the purpose of this part of ISO 945.
