NJS Torsion tests
Model NJS is used to perform for torsion tests on various materials by imposing a torque.
There are two test methods:
-
Automatic test: Turn the hand wheel until the test rod breaks. The testing machine will automatically test the yield torque M1 and the maximum torque M2.
-
Manual test: To choose the test angles and torques of any 9 points during the test period and record them.
The machine can retrieve or print latest test results after a test.
It is suitable for applications in labs environment in scientific research dept., colleges and industrial enterprises to test the mechanical properties of materials under torsion conditions.
This series of testing machines conforms to standards of ASTM A938, ISO 7800:2003.，GB/T239-1998, GB10128 and others equivalent.
