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
Product Advantages:
Evaluates Torsional Ductility: Directly measures the wire's ability to withstand twisting before fracture.
Standardized Testing: Enables testing according to widely recognized national and international standards.
Reveals Defects: Torsional stress can highlight material imperfections or inconsistencies not apparent under other tests.
Supports Quality Control: Provides a reliable method for ensuring consistent wire quality.
Versatile: Can perform both unidirectional and bidirectional torsion tests.
Controlled Parameters: Allows for precise control of twisting speed and specimen length for repeatable results.
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)
