Why calibrate a torque wrench?
Torque wrenches are as only good as they can maintain their accuracy. An out of tune wrench can result in many dollars of damage. You can imagine the difference it would make with a racing car that depends on good engine compression and stable wheels. Your torque wrench needs to go to a place that can guarantee the accuracy of the calibration to National Institute of Standards Technology (NIST) standards.
What is Calibration?
Calibration is the comparison of your instrument to a working standard that has been previously calibrated to a higher standard like NIST. Radial force of the wrench is measured and compared to the standards in the allowable ranges. A wrench is in calibration if it can maintain 4 to 6 percent above or below what is allowable by the International Standards Organization (ISO).
