Torque

The Laboratory can provide calibration services for manually operated torque wrenches and drivers, mechanical torque testers (e.g. torque meter) and electronic torque testers (e.g. torque transducer) from 0.05 to 1 000 N.m.

For torque wrench and driver calibration, the reading of the test instrument will be compared against the reading of a measurement standard torque transducer at, or nearest to, 20%, 60% and 100% of maximum capacity of the submitted instrument unless otherwise requested.

For a precision torque tester, the test device will be calibrated against the torque generated by weights hanging at the end of a beam. Calibration is made by applying torque of known values to the test device in sufficient number of steps (normally about 7) distributed throughout its usable range, from lower test values to full scale capacity.
