Analysis on Confirmation of the Changed Methods of Tensile Test for Metallic Materials at Room Temperature

By means of the tensile tests of standard tensile samples of low alloy steel under different loading conditions, the influence of control mode and loading rate on mechanical properties of materials was analyzed. And in order to confirm that the laboratory has the ability to continue to meet the requirements of the test standard, combining with tensile test methods for metallic materials at room temperature, it was discussed in detail including the measures should be taken by the laboratory after the testing standards were changed, as well as to the reconfirmed methods, procedures and problems should be paid attention to.
