Torque
During calibration, clockwise and counter-clockwise torque measurements are carried out, and the data related to the calibration is presented on a calibration certificate along with the measurement uncertainty of each measurement. The emphasis is placed on the quality of the calibration certificate to assure compliance with the ISO/IEC 17025:2017 standard.
The lbf-ft is an SI-derived unit defined in the SI base unit of the N-m. Miller Instruments may report torque in Newton-meter or pound-force-ft units on a calibration certificate. Although lbf-ft is not an SI unit, the relationship between the Newton and meter is known, and thus measurement traceability to the SI may be established. Our scope of SCC accreditation in torque may be found on the National Research Council’s CLAS website:
