Materials testing machines - Calibration of static torque measuring devices
|Publication Date:||1 December 2005|
|ICS Code (Mechanical testing):||19.060|
This standard is generally applicable to torque measuring devices by which the torque is defined by measuring the elastic deformation of a loaded member or a proportional measurement of it. The torque measuring device is defined as the complete device, from the torque transducer up to and including the display unit.
This standard is applicable to the calibration of torque measuring devices for static calibration of testing machines. Furthermore, it should be used for torque measuring devices for general applications (e.g. as torque sensors in power assembly tools, performance test benches etc.) as well as for transfer standards. The procedure for the classification of these devices is described, as well as a suggestion for determining the measurement uncertainty (see Annex C). When using the torque measuring device for measuring alternating torques, additional consideration is required in accordance with Annex E. This standard is not applicable to torque wrenches.
