Testing machines for torsion testing

Testing machines for torsion testing are mainly used in science, research and teaching, in testing laboratories and in production control during production.They are used to determine the torque load of specimens made of different materials in static tests, e.g: 

  • Plastics, composite materials
  • Screws, cardan shafts
  • Twisting tests on wires according to DIN ISO7800 and ASTM A938 as well as alternating twisting tests on wires according to DIN ISO 9649
  • Calibration of torque sensors
