A) the main features:
Unidirectional twist: the sample uniformly rotating around its own axis in one direction 360 degrees as a twist to a predetermined number of times or specimen fracture
Bidirectional twist: the sample evenly around its own axis in one direction of rotation of 360 degrees as a twist to the specified number of times, the same number in the opposite direction of rotation or specimen fracture.
B) the main purposes:
Metal wire torsion testing machine for measuring the diameter (or characteristic dimension) of the metal wire 0.1-10.0mm ability to withstand plastic deformation and display wire surface and internal defects in one-way or two-way reversed.
C) Applicable standards:
Metal wire torsion testing machine for People's Republic of China standard GB / T 239-1999 (metal wire torsion testing methods), also apply to the international standard ISO 7800: 1984 (unidirectional metal wire torsion test methods) and ISO 9649: 1990 (metal wire bidirectional torsion test method).
