See Chinese contents: GB/T 228-2002 GB/T 228-2002: Metallic materials -- Tensile testing at ambient temperature
This Standard specifies the principle, definitions, symbols and designations, test piece and its dimension measurement, testing apparatus, conditions of testing, property determination, rounding off of numerical values of determination results, and test report for tensile testing of metallic materials. This Standard applies to determination of tensile properties of metallic materials at ambient temperature. Whereas, the tensile testing for the metallic products with a small cross section dimension such as metal anchors, ultra-fine wires and capillary tubes requires separate agreement.
