Calibration Services
Mass and Related Quantities: Torque Measurements
General
The Mass and related quantities Laboratory of SCL 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.
Torque Wrenches / Torque Driver
For torque wrench and driver calibration, the meter's reading / indicator reading of the torque wrench / driver under test will be compared against the reading of the laboratory's reference torque transducer at, or nearest to, 20%, 60% and 100% of maximum capacity of the instrument under test unless otherwise requested.
Torque Testers / Torque Transducers
Calibration for Torque Testers / Torque Transducers
For a precision torque tester / torque transducer, the tester / transducer under test 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 tester / transducer under test in sufficient number of steps (normally about 7) distributed throughout its usable range, from lower test values to full scale capacity.
