The metal material tension test is the most important content testing its quality and production process.Various index parameters obtained during testing process are a key factor reflecting mechanical properties of metal material,however,in actual teasion test,its test result and test parameters can be under the influence of many fac-tors,making accuracy of the test sample,tester calibration,holding method correctness and tension rate control pro-duce marked influence on the test results.Making process of the test sample must comply with strict standard in or-der to ensure the whole material pwerformance.
