This standard specifies the terminology, principles, and methods for testing the torsional properties of metallic materials at room temperature. It determines multiple torsional mechanical properties, such as shear modulus, specified non-proportional torsional strength, and torsional strength, by applying torque to cylindrical specimens until fracture. The core instrument required for performing this test is a torsion testing machine (e.g., a microcomputer-controlled torsion testing machine or a digital display torsion testing machine), which should be capable of precisely controlling the torsional speed and measuring torque and torsional angle.
