Tensile tests are used to clarify the basic mechanical properties of tested specimens and the obtained stress-strain relation gives important information for plastic flow under metal forming processes, i.e. formability and anisotropic properties. The specimen size, test procedure and data measurement method are specified under tensile test standards in order to assure reliability of the tested data. However, many various tests are performed in industrised, universities and research institutes for their convenience in reality. In this study we performed tensile tests according to the different test method and compared their results. These finding will contribute the understanding of each test method.
