Torque Calibration Services

Quality Testing Calibration (QTC) provides ISO/IEC 17025 accredited torque calibration services for manufacturers, laboratories, and industrial operations that rely on accurate torque application and verification. Proper torque control supports product quality, equipment reliability, and compliance requirements across assembly and testing environments.
Our torque calibration services are performed under an accredited quality system with measurement traceability maintained through calibrated reference standards. Certificates include documented results suitable for audits and quality system requirements.
ISO/IEC 17025 Accredited & NIST-Traceable
QTC performs torque calibration under ISO/IEC 17025 accreditation as recognized by A2LA. Accredited capability and uncertainty are defined in our official scope:

Accredited Torque Calibration Ranges
QTC’s current A2LA Scope of Accreditation (Cert. No. 4699.01) lists accredited torque capability for torque analyzers and torque wrenches as follows:
| Parameter | Accredited Range | CMC (±) |
|---|---|---|
| Torque Analyzers | 5 to 50 lbf·in | 0.23% of reading |
| Torque Analyzers | 25 to 250 lbf·in | 0.28% of reading |
| Torque Analyzers | 25 to 250 lbf·ft | 0.28% of reading |
| Torque Analyzers | 100 to 600 lbf·ft | 0.17% of reading |
| Torque Wrenches | 1 to 250 lbf·ft | 1.4% of reading |
| Torque Wrenches | >250 to 600 lbf·ft | 0.65% of reading |
Accredited torque calibration applies within the ranges shown above. Actual measurement uncertainty may vary depending on the specific device and calibration conditions.
Torque Calibration Methods
Torque calibration is performed using controlled application and verification of torque values across multiple points within the device’s operating range. This process helps confirm accuracy and repeatability for torque tools and verification equipment used in production and quality programs.
- Calibration of torque wrenches across applicable set points
- Calibration and verification of torque analyzers
- Documented results and uncertainty reporting
- Calibration certificates suitable for audits and quality records
If your torque calibration program requires specific reporting formats, acceptance criteria, or decision rules, those requirements can be addressed at the time of quote.
