Proper torque wrench calibration by a professional calibration lab is a must to ensure you are using reliable tools in each job you do. Torque wrenches should be calibrated annually, more often if they are being used daily or if your torque wrenches are being used for applications that require high levels of precision and accuracy.
if your torque wrench has been dropped or otherwise damaged you may want to have its calibration checked. National and international standards for torque wrench calibration intervals are every one year or every 5,000 cycles- so whichever comes first would be the time to get your torque wrench checked and calibrated to keep it up to standards.
Proper torque wrench calibration can be time consuming, so some manufactures have come out with their own torque checking devices to be used by the torque operator. These manufactures devices are quick and easy ways to check if your tool is in good shape, but these devices are not highly accurate which is why for critical applications you must have your torque wrench calibration done by a professional calibration lab
A regular schedule of torque wrench calibration will eliminate errors in your work due to the wrench being out of tolerance. While there is information available on how to perform your own torque wrench calibration, and devices for do-it-yourself checking from manufacturers, only a trained technician with NIST certified equipment can supply you with the highest level of torque wrench calibration services; and if you need to have a calibration certificate, doing a calibration by yourself is out of the question.
