3种金属材料夏比冲击试验方法标准分析及对比

Analysis and Comparison of Three Charpy Impact Test Method Standards for Metallic Materials

从试验原理、试样要求、试验设备、试验程序、冲击试验结果处理及报告等方面对GB/T229—2007,EN ISO 148-1:2016,ASTM E23—18等3个金属材料夏比冲击试验方法标准进行了分析和对比。结果表明:GB/T 229—2007和EN ISO 148-1:2016的内容基本相同;ASTM E23—18冲击试验标准相比GB/T 229—2007和EN ISO 148-1:2016,在试样尺寸及设备尺寸公差方面要求更为严格,相关的试验规定也更加详细。

The Charpy impact test method standards for metallic materials(GB/T 229—2007,EN ISO148-1:2016 and ASTM E23—18)were analyzed and compared from the aspects of test principle,sample requirements,test equipment,test procedures,impact test results processing and report.The results show that the contents of GB/T 229—2007 and EN ISO 148-1:2016 are basically the same.Compared with GB/T 229—2007 and EN ISO 148-1:2016,ASTM E23—18 impact test standard has more stringent requirements on specimen size and equipment dimension tolerance,and the relevant test regulations are more detailed.
