- Scope
- This British Standard specifies a method for the calibration and classification of torque measuring devices using continuous torque application where the inertial effects are minimal. This includes torque measuring devices used for the calibration of hand torque tools conforming to BS EN ISO 6789, and torque measuring devices conforming to BS 7882. The information to be given on the certificate of calibration is also specified in this standard. Annex A provides diagrams of the continuous application of torque, and examples for the calibration of torque measuring devices. Annex B gives an example of determining uncertainty of the calibration results of the torque measuring device. Annex C shows how to calculate mechanical and electronic bandwidth.
