The metal wire torsion testing machine is suitable for determining the ability of metal wires with a diameter (or characteristic dimension) of 0.05–30 mm to withstand plastic deformation during unidirectional or bidirectional torsion, and for revealing surface and internal defects of the wire.
Applicable Standards:
The metal wire torsion testing machine complies with the national standards of the People's Republic of China, GB/T 239.1-2012 "Metallic materials—Wire—Unidirectional torsion test method" and GB/T 239.2-2012 "Metallic materials—Wire—Bidirectional torsion test method". It also complies with the international standards ISO 7800:1984 "Metallic materials—Wire—Unidirectional torsion test" and ISO 9649:1990 "Metallic materials—Wire—Bidirectional torsion test".
