| Abstract: | The basic concept for the uncertainty of the testing has been described in this article, as well as the evaluation process and the basic method of the uncertainty during the mechanical property testing. And the relative uncertainty of the steel tensile testing during the mechanical property testing has been well evaluated, so that reliability of the conventional testing results in the laboratory has been verified as well. |
