GB/T 228.1-2021 specifies the method for tensile testing of metallic materials at room temperature (10°C–35°C). It is applicable to the performance determination of various metallic materials and products in multiple forms, such as plates, bars, and tubes. The standard defines the test procedures, parameter control, and result calculation requirements. The core equipment includes a universal testing machine, extensometer, and dimensional measuring tools such as calipers. By applying axial tensile loads, key indicators such as yield strength, tensile strength, and elongation after fracture are measured. For some materials, the test process must be controlled according to strain rate or stress rate. This standard provides a unified and reliable technical basis for material quality acceptance, product design, and process optimization.
