What should a torque wrench calibration log include?

A torque wrench calibration log should record instrument identification (make, model, serial number, drive size, torque range, asset number), calibration date, technician name, reference standard used (make/model/serial/certificate number), test points tested (typically 25%, 50% and 75% of full scale), as-found readings at each test point, as-left readings after adjustment, deviation from set value, pass/fail status for each test point, overall result, and next calibration due date. A separate history log allows multiple calibration events to be tracked over the instrument service life.

How often should torque wrenches be calibrated?

AS ISO 6789 recommends calibration at least annually or every 5,000 uses, whichever comes first. In practice, most maintenance and safety-critical applications require annual calibration at minimum. Torque wrenches should also be calibrated after any significant impact, drop, overload or suspected damage, and when the tool has been out of service for an extended period. High-usage environments (production, assembly lines, heavy industry) may require more frequent calibration intervals.

What is the acceptable accuracy tolerance for a torque wrench?

AS ISO 6789-1 specifies that type I torque wrenches (indicating) must be accurate to within ±4% of reading, and type II (setting) wrenches must be accurate to within ±4% of reading in the clockwise (tightening) direction. Some quality management systems and safety-critical applications set tighter tolerances. The acceptable tolerance for your application should be defined in your calibration procedure or quality management system.

Who can calibrate a torque wrench in Australia?

Torque wrenches can be calibrated in-house if your organisation has appropriate calibrated reference equipment and a documented calibration procedure. For traceable calibration to national standards, calibration should be performed by an NATA-accredited laboratory or a technician using equipment with a current NATA-traceable certificate. For safety-critical applications (pressure systems, structural connections, aerospace), NATA-accredited calibration is strongly recommended.

What happens if a torque wrench is found out of tolerance during calibration?

If a torque wrench fails calibration at any test point, it must be adjusted and retested. If adjustment brings the wrench back within tolerance, the as-left readings are recorded and the wrench can be returned to service. If the wrench cannot be adjusted to meet tolerance, it should be removed from service, tagged as out of tolerance and either sent for repair or disposed of. Critically, you should review any safety-critical fasteners tightened with the wrench since its last successful calibration, as those joints may need to be re-torqued with a verified tool.

What is a torque wrench calibration log?

A torque wrench calibration log is a formal record that documents the calibration of a torque wrench against a traceable reference standard. Calibration verifies that the wrench applies the intended torque value accurately within an acceptable tolerance, typically within plus or minus 4% per AS ISO 6789. The log captures the instrument details, the calibration event data (reference standard, test points, readings, deviations, adjustments), the outcome (Pass/Fail), and the next calibration due date. A calibration history register on the second page tracks multiple calibration events over the life of the instrument, providing a consolidated view of tool accuracy trends and drift patterns.

In Australia, torque wrench calibration is governed by ISO 6789:2017 (Assembly tools for screws and nuts, Hand torque instruments), adopted locally as AS ISO 6789. ISO 9001:2015 Section 7.1.5 requires that monitoring and measuring resources, including torque wrenches used in quality-controlled processes, be calibrated at specified intervals and records maintained. Calibration records are required wherever torque is a safety-critical parameter, such as structural connections, pressure system fasteners, vehicle wheel nuts and lifting equipment. For NATA-accredited laboratories and facilities, calibration must be traceable to national measurement standards through the National Measurement Institute. WHS Regulations 2011, Chapter 5, require that plant used at a workplace be maintained and inspected in accordance with manufacturer recommendations, which includes calibrating torque tools that affect fastener integrity. Maintaining a calibration log provides documented proof that safety-critical fasteners are being tightened with verified, accurate tools, which supports due diligence, audit compliance and legal defensibility in the event of a fastener-related incident.

Benefits of using this torque wrench calibration log

Safety assurance: confirms that safety-critical fasteners (wheel nuts, structural bolts, pressure systems) are tightened to the correct torque, reducing risk of failure.
ISO 9001 compliance: quality management systems require monitoring and measuring equipment to be calibrated and records maintained.
Traceability: links each calibration event to a traceable reference standard, supporting audit and regulatory requirements.
Detect out-of-tolerance tools: as-found readings reveal whether the wrench was in tolerance before adjustment, providing an early warning of drift.
Maintenance planning: calibration history shows whether calibration intervals are appropriate and whether repeated adjustment suggests a worn or damaged tool.
Legal and insurance protection: documented calibration records demonstrate due diligence if fastener failures are investigated.

How to use this torque wrench calibration log

Record the instrument details at the top of page 1: make/model, serial number, drive size, torque range and asset/ID number.: Verify the torque wrench identity against your tool register. Record the drive size and full-scale torque range, as these determine the test points used during calibration.
Record the reference standard details (make/model, serial number, certificate number) to establish traceability.: The reference torque tester must have a current calibration certificate traceable to national standards. Record the certificate number and confirm the reference tester accuracy is at least four times better than the wrench tolerance.
Allow the torque wrench to stabilise at room temperature before testing. Apply the wrench five times at the set torque to condition it before recording readings.: Temperature affects torque tool accuracy. Let the wrench sit at room temperature for at least 30 minutes if it has been stored in extreme conditions. The five conditioning applications warm up the internal mechanism and improve reading consistency.
Set the wrench to 25% of its full scale. Apply torque to the reference tester. Record the actual displayed torque as the as-found reading. Calculate deviation (%). Mark Pass or Fail based on your acceptance criteria (typically ±4% per AS ISO 6789).: Apply torque smoothly and steadily to the reference tester. Record the peak reading displayed on the reference instrument as the as-found value. Calculate deviation as a percentage of the set value and compare against the acceptance criteria.
Repeat at 50% and 75% of full scale, recording as-found readings and pass/fail for each.: Test at each point in the same direction (typically clockwise for tightening). Take multiple readings at each test point as required by AS ISO 6789 and record the average or individual readings per your calibration procedure.
If any test point fails, adjust the wrench and record the as-left readings at each test point. Note the adjustment made.: Use the manufacturer adjustment mechanism to bring the wrench into tolerance. After adjustment, repeat the full calibration sequence and record the as-left readings at each test point. Document the specific adjustment performed.
Record the overall result (Pass/Fail), set the next calibration due date, and sign off.: The overall result is Pass only if all test points are within tolerance after any adjustment. Set the next calibration due date based on your calibration schedule (typically 12 months or 5,000 uses). The technician must sign the record.
Transfer a summary entry to the calibration history log on page 2.: Record the calibration date, technician name, next due date, overall result and certificate number in the calibration history register. This provides a consolidated view of the wrench calibration status over its service life.

How often should you complete this log / register?

AS ISO 6789 recommends torque wrenches be calibrated at least once per year or every 5,000 uses, whichever occurs first. For tools used in safety-critical applications - structural bolting, wheel fasteners, pressure equipment - annual or more frequent calibration is standard practice. Many quality management systems specify calibration intervals in their calibration schedules based on risk level and usage frequency.

Torque wrenches should also be calibrated immediately after any significant shock, drop or overload event, after extended storage, and before use on any safety-critical application. A calibration label or tag attached to the wrench should clearly display the calibration due date, enabling operators to identify out-of-date tools before use.
