Torque Calibration Services
Infinity Group operates an Accredited Torque Calibration Laboratory, offering calibration of torque wrenches and screwdrivers to the internationally recognised standard ISO 6789 up to 1,500Nm.
ISO 6789 Standards
Accredited calibration for torque wrenches and screwdrivers to both ISO 6789:2003 and the newer ISO 6789:2017.
Tools & Meters
Calibration for torque closure meters, analysers, and watches, in addition to standard hand tools.
Wide Scope
Covering ranges from 0.05cNm up to 1,500Nm for hand torque tools and analysers.
Full Certification
With every calibration performed, we issue a certificate quoting full measured results.
ISO 6789:2003 vs 2017
Understanding the differences between the withdrawn standard and the new requirement.
ISO 6789:2003 (Old)
Classified as "withdrawn" but still technically valid. We can continue to calibrate to this standard if required.
ISO 6789:2017 (New)
Requires huge additional work to identify uncertainty contributions (reproducibility, loading position, output drive orientation).
Please specify which standard you require when sending tools.
Laboratory Scope
Most torque tools get a lot of abuse in service. Periodic calibration ensures they continue to give reliable, accurate performance.
Hand Torque Tools
Accredited calibration of wrenches and screwdrivers to ISO 6789:2003 or 2017.
Range: 0.2Nm to 1,500NmMeters & Analysers
Traceable calibration of torque meters and analysers.
Range: 0.05cNm to 1,000NmManufacturers Supported
