Why Regular Calibration is Vital to Industrial Torque Wrench Capabilities?
Having the most accurate and reliable tools is vital to mechanical services. It is natural for torque wrenches to go out of calibration with time and consistent use. Regular calibration servicing will ensure that your tools are as accurate and effective as possible.
Why is Torque Wrench Calibration Essential?
In most cases, it is presumed that a manual or hydraulic torque wrench will distribute the demanded torque value if set appropriately. However, torque wrenches have moving parts that will be subject to wear. They are also exposed to harsh operating conditions in the field, which increases the risk of damage. The need to control torque is a very important task to provide quality and safety. The allowable window of calibration error is 5% and any error beyond that may seriously disturb the performance of the tool.
How Often Should Wrenches Be Calibrated?
There is no one-size-fits-all practice for torque wrench calibration. Since there are different types of wrenches used for an assortment of jobs, each requires calibration after specific intervals to perform the job well.
It’s understandable that not everyone uses the same schedule for calibration. For some professionals, it’s once a year and others have their tools calibrated every six months, depending on their ISO QC protocol. Many experts suggest calibration after 2,500 repetitions, based on the idea that a tool’s performance is affected between 2,500 and 3,000 repetitions. A good rule of thumb to follow is the more the tool is used, the more often calibration will be needed.
Helpful Tip: The Calibration Interval Committee of NCSL International has published Recommended Practices for Calibration to help guide you to a reliable calibration schedule.
Regular calibration will help ensure your tools are working to their full potential and will provide you peace of mind that their accuracy is on point.
