To ensure that torque wrenches can accurately measure the tightness of a fastener, they must undergo regular calibration, as mentioned earlier. ISO 6789-1:2017 refers to the requirements and methods for testing quality and design conformance for hand torque tools. You can estimate the cost of torque wrench calibration while keeping the points mentioned earlier in mind. What Can Happen If My Torque Wrench Is Not Calibrated? We offer calibration for new and existing equipment, with specialists in our laboratory offering RS and UKAS-accredited services – which is recognised internationally as the industry mark of quality. Using your new torque wrench, apply a force to the handle. You can test if it is calibrated by seeing if it will move or not.

This tool is essential for throughbolts as it not only sets the anchor but also creates the necessary clamping force to secure the fixture. Testing the tools highlights any potential problems and allows them to be fixed before they can lead to a serious issue. Calibration also ensures the user can have confidence in the accuracy of their tool and that it complies with international standards. How often should they be calibrated?

If you're working with metric units, start by converting the weight to Newtons. To do this, multiply the number of kilograms by 9.807. In this example 9.07 kg x 9.807 = 88.94949 Newtons. Then, multiply the number of Newtons by the length in meters: 88.94949 Newtons x 0.6096 meters = 54.2 Newton meters. Torque wrenches are critical tools used in a wide variety of industries. Their accuracy is essential to ensure safe and efficient operation. The consequences of not having a calibrated torque wrench can be severe, leading to costly mistakes, downtime, and safety hazards. While calibrating a torque wrench is a relatively straightforward process, it requires specialised equipment and expertise – best provided by a professional calibration service. Depending on the precision requirements of your job, you may be able to work with a torque wrench with a couple of millimeters tolerance and can, therefore, consider you torque wrench to be calibrated. How to Calibrate a Torque Wrench Where specialised applications are concerned, the tightness of bolt fixing is critical to safety. Cromwell does not recommend you use anything other than the correct tool for the job. Torque wrench calibration is important to ensure the accuracy of torque readings and prevent under or over-tightening of bolts which can lead to equipment failure.

Ideally, torque wrenches should be calibrated at least once a year or after 5,000 cycles, whichever comes first. A torque wrench of any frequency can go out of calibration. It is essential to test the torque wrench periodically to maintain accuracy. Here are some tools to test the torque wrench calibration: Regular torque wrench calibrations are essential if you want your torque instruments to perform optimally over the long term. Failure to do so can harm the continuity of your operations, which can have a negative impact on both your productivity and your bottom line. Precise torque measurements give you the ability to tighten fasteners with the correct amount of tension. This enables you to avoid any costly mutual connection failures. For example, if your torque wrench is 24 inches long (a standard length for torque wrenches), the handle may start 18 inches along the tool.Set your new torque wrench to 25-foot pounds by placing the handle of the torque wrench on the mark on your scale. It’s vital to regularly calibrate instruments, as their accuracy will reduce over time and with use. The permitted frame of calibration error is 5% – with any error beyond that potentially affecting the performance of the tool quite seriously, which could lead to liability for product failure. Repeat this process at least three times to ensure accuracy and consistency. Once you’re confident that your torque wrench is properly calibrated, you can start using it with confidence. Remember to recalibrate regularly to maintain accuracy.
