How often should the accuracy of the tension calibrator be confirmed?

The accuracy of the tension calibrator should be confirmed annually to ensure it is functioning correctly and providing reliable measurements. Regular calibration is critical in maintaining the integrity and safety of structural steel connections, as inaccurate tension measurements can lead to structural failures due to inadequate bolt tensioning. Annual checks help to confirm that the tension calibrator remains within acceptable limits and adheres to industry standards, supporting consistent and reliable results in bolting practices. This approach strikes a balance between thoroughness and practicality, ensuring that any potential issues are identified in a timely manner without imposing overly frequent checks that might disrupt operations.
