Torque calibration
Torque wrench calibration: when to calibrate and how to prepare
Torque wrench calibration helps you assess measured torque against the requirements of your assembly or maintenance work.
What is torque wrench calibration?
Calibration compares the tool's torque with a reference under defined conditions and reports the results and associated uncertainty. Adjustment or repair is a separate service to agree in advance.
When to calibrate and what to send
Follow your risk-based schedule and consider recalibration after impact, overload, repair or suspected malfunction. Send the make, model, range, unit, working points, direction and acceptance criteria, along with any prior certificate.
SK service and accredited scope

FAQ
Does calibration include adjustment?
Adjustment or repair must be agreed separately; request as-found results before work begins if needed.
