Calibration, Service & Repair

Properly maintained tools for safe and accurate bolt tightening

CALIBRATION

Calibration of manual, pneumatic, hydraulic and electronic tools, using equipment traceable to UKAS laboratories and capable of handling torque output from 10 to 100,000 Nm.

We offer calibration of hand torque wrenches to ISO 6789-1: 2017 and
ISO 6789-2: 2017.

ISO 6789 – 2:2017 Is the new calibration standard. The test rig is used to gather uncertainty data, whilst also controlling speed and technique to determine the torque peak measurement.

The data produced is then used to create a certificate of calibration.
 

ISO 6789 – 1:2017 can be used as an alternative to the above, this method uses the same test rig, but does not use uncertainty data collection. This method will highlight any readings outside the tools recommended tolerances.

The data produced is then used to create a certificate of conformance.

W. Christie Industrial Ltd offer either of the above standards to its customers when testing tools.

SERVICE

Scheduled servicing of torque tools and bolting equipment to ensure they are delivering the correct torque.

REPAIR

Tool inspections are carried out in order to determine any repairs or maintenance required and to provide a quotation. The repair and maintenance service is available for all types of torque tool.
