| Abstract: | 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. |
