This Standard specifies the principle,definitions,symbols and designations,test piece and dimension measurement,testing machine,testing requirment,properties’ determination,rounding of results and test report for tensile testing method of metallic material.
This Standard is applied to determine the mechanical properties of tensile testing at ambient tempera-ture for metallic material.With the agreement,the tensile test method can be used for the smaller dimension of cross-section metallic products,e.g.metallic foil,superthin wire and capillary tubing.
