Just like any other measuring instrument, torque tools can drift and fall out of calibration. This can cause negative outcomes when using torque tools, including cause of defects and faulty products. To prevent the negative repercussions, torque tools should be calibrated and tested regularly. A routine calibration schedule should be created for each torque tool to ensure its calibration is up to par when being used.
To assist you with creating a torque tool calibration schedule, we have created a guide below on how to determine frequency of torque tool calibration.
A general rule of thumb for torque tool calibration is to recalibrate a torque instrument every six to twelve months. However, use of this rule of thumb is rare for many reasons. Many factors play into when a torque tool needs to be calibrated and for this reason, calibration frequency for each torque tool owner/user.
When calculating torque tool recalibrate, the following questions should be asked and considered:
While the above factors are all very important to consider when determining a torque tools calibration schedule, the real key to determining frequency is judgement. Judgement should be used to decide a routine and stick to it. The more regularly you calibrate your torque tool, the more likely it is to not fall out of calibration and cause severe repercussions.
Considering calibrating your own torque wrenches?
This guide helps you make an informed decision on whether that’s the best idea.
