What is torque wrench calibration?

A torque “wrench” is really a precise torque instrument used to accurately apply a predetermined

amount of torque to a fastener. “Calibration” is a set of operations to check and adjust the measuring

performance of a torque wrench to establish accuracy standards.

Torque wrench calibration standards are set by The American Society of Mechanical Engineers (A.S.M.E)

and are the recognized standard in the U.S and internationally. This is the standard used to manufacture

and test all CDI torque wrenches.
