Metal Wire Torsion Tester

Applicable standards:

GB/T 239.1-2012 "Metal materials wire Part I unidirectional torsion test method"

GB/T 239.2-2012 "Metal materials wire Part II Bidirectional torsion test method"

ISO 7800:2003 "Test method for unidirectional torsion of metal wires"

ISO 9649:1990 Test method for bidirectional torsion of metal wires

Test principle:

Unidirectional torsion: The sample rotates 360 degrees evenly around its axis in one direction as a single torsion to the specified number of times or the sample breaks.

Two-way torsion: the sample rotates 360 degrees evenly around its axis in one direction as a torsion to the specified number of times, and then rotates the same number of times in the opposite direction or the sample breaks.

Main parameters:

1, clamping metal wire diameter range: 3.0≤d(D)<5.0

2, the space between the two fixtures: 500mm

3. Clamp range: 3.0-5.0mm

4, twisting speed: 30, 60r/min

5. Power supply: AC220V 50Hz

6, Noise: <70 dB(A)
