Torque Testers Flexible-Beam and Torsion Bar Types 5 Oz-in. To 1000 Lb-Ft

摘要

The procedure describes the calibration of flexible beam and torsion bar type torque testers within the range of 5 oz-in. to 1000 lb-ft. The Test Instrument is used in determining the accuracy of torque wrenches. The flexible beam type has a beam as its measuring element, that is flexed in proportion to the torque applied to the input shaft. A dial-pointer system indicates the amount of flexure in terms of the applied torque. The torsion bar type operates in a similar manner, except that the measuring element is a bar which is twisted in proportion to the applied torque.
