The metal wire torsion testing machine complies with the Chinese standards GB/T 239.1-2012 "Metallic materials – Wire – Part 1: Simple torsion test" and GB/T 239.2-2012 "Metallic materials – Wire – Part 2: Reversing torsion test," as well as the international standards ISO 7800:2003 "Metallic materials – Wire – Simple torsion test" and ISO 9649:1990 "Metallic materials – Wire – Reversing torsion test."
This metal wire torsion testing machine is suitable for determining the ability of metal wires with diameters (or characteristic dimensions) of 10μm-10mm to withstand plastic deformation under unidirectional or bidirectional torsion, and for revealing surface and internal defects in the wire.
