It is mainly used for the detection of torsion and mechanical properties of materials and finished products at room temperature, as well as for the torsion failure of materials and finished products. The test specimen is installed between adjustable clamping fixtures, which can be used to test the torsion mechanical properties of different tested specimens. The test machine uses computer control operation, and the software synchronously displays the curves of torque - time, twist angle - time, torque - twist angle, torque - angle and so on. The parameters such as angle, torque and torque peak are displayed in real time, and the test results can be stored and printed.

Implementation standard: GB/T 10128, "torsion test method for metallic materials at room temperature", JJG 269 "verification regulation for torsion testing machine".
