Njs Digital Steel Wire Torsion Test Equipment

Introduction:  

NJS-X Digital Steel wire torsion testing machine/ wire torsion tester is used to execute metal wire torsion test, measure the metal wire endure of plastic distortion ability in single or double direction torsion condition; check the surface or internal defect.

ISO 9649 Metallic materials -- Wire -- Reverse torsion test.  

GB/T 239.2 Metallic materials -- Wire - part 2. Reverse torsion test..

This Standard specifies a method for determining the ability of metallic wire of diameter dimension from 0,3 mm to 10,0 mm inclusive to undergo plastic deformation during reverse torsion. This test is used to detect surface defects, as well as to assess ductility.

Principle: 

A test piece of wire is twisted a specified number of turns through 360° around its own axis in one direction, and then a specified number of turns through 360° in the opposite direction.
