Short answer
A torque wrench calibration log records each calibration of one wrench: its identity, the reference torque tester and certificate, test points, as-found and as-left readings, deviation, pass or fail and next due date. A calibration laboratory or trained in-house technician completes it. ISO 6789-2:2017 covers calibration of hand torque tools; intervals come from your quality system or the manufacturer, often 12 months in practice.

Key takeaways
- The MapTrack torque wrench calibration log has 8 columns and room for 6 entries. Columns: Test Point, Set Torque (N·m), Reading 1 (N·m), Reading 2 (N·m), Reading 3 (N·m), Mean (N·m), Deviation %, Pass / Fail.
- ISO 6789:2003 was split in 2017: ISO 6789-1 sets conformance requirements and ISO 6789-2 covers calibration of hand torque tools.
- Recalibrate after a drop, overload or repair, whatever the due date, and record the reason on the log.
- If a wrench fails, tag it out of use and review safety-critical joints tightened with it since its last good calibration.
- Record the reference tester's certificate number so each result traces back to national measurement standards.

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 covered by ISO 6789-1:2017 and ISO 6789-2:2017 (Assembly tools for screws and nuts, Hand torque tools). ISO 9001 clause 7.1.5 covers monitoring and measuring resources, which include torque wrenches used in quality-controlled processes, and the traceability of measurement results. 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 (regulation 213), and correct fastener torque is part of that work; Part 5.1 itself does not apply to hand tools that rely only on manual power and are supported by hand (regulation 185). 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.

What to include in a torque wrench calibration log
This torque wrench calibration log covers 10 key areas:
- Instrument details: make/model, serial number, drive size, torque range, asset/ID number, and next calibration due date.
- Calibration event details: date calibrated, calibrated by, calibration location and environmental conditions (temperature, humidity where required).
- Reference standard: make/model, serial number and certificate number of the reference torque tester used, confirming traceability.
- Test points: 25%, 50% and 75% of full scale, tested in at least three directions as required by AS ISO 6789.
- As-found readings: actual torque applied at each test point before any adjustment, with deviation and pass/fail.
- As-left readings: readings after adjustment, confirming the wrench is within tolerance before being returned to service.
- Adjustment notes: details of any adjustments made during calibration.
- Overall result: Pass or Fail for the calibration event.
- Calibration history register: 8-row table on page 2 capturing date, calibrated by, next due, result and certificate number for each calibration event over the life of the instrument.
- Technician sign-off: declaration and signature.
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.

A common calibration interval is once a year or every 5,000 uses, whichever comes first; confirm it against ISO 6789-1:2017 and your calibration procedure. 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.
