Torque Calibration Machines

Our Universal range of torque tool calibration machines are designed to feature automated operation to allow for faster torque wrench and torque screwdriver calibrations to ISO 6789:2017 international standards whilst also minimising operator effort and error.

We also have the equipment to perform BS 7882:2017, BS 7996:2018 and DIN 51309 calibrations on torque measuring devices via automated means, significantly reducing the calibration times and necessary operator effort.

Frequently Asked Questions

ISO 6789:2017 is the latest edition of the ISO 6789 standard for the calibration of manual torque tools. The 2017 version of the standard is divided into 2 parts:

Part 1 (BS EN ISO 6789-1:2017): Requirements and methods for design conformance testing and quality conformance testing.

Part 2 (BS EN ISO 6789-2:2017): Requirements for calibration and determination of measurement uncertainty.

More information can be read in our white paper: https://www.awstorque.co.uk/files/AWS%20White%20Paper%20-%20ISO%206789-2017%20v4.pdf

BS 7882:2017 is the latest edition of the BS 7882 standard for the calibration and classification of torque measuring devices.

This is the globally accepted British standard, focussing specifically on the methodology for calibration, calculation of the uncertainty of measurement, and determination of the overall classification for the torque measuring device under test.

This is an alternative solution to that prescribed briefly in Annex C of ISO 6789:2017.

Automated operation such as is seen on the AWS UTWCM and UTSCM means that the user controls the calibration machine via a handheld pendant controller, with the torque being applied via a stepper motor and gearbox combination within the machine rather than the user having to apply force to the tool or device themselves, by hand or applying weights.

A comprehensive list of benefits automated operation will bring to your laboratory can be read in our blog: https://www.awstorque.co.uk/support/white-papers/benefits-of-automated-operation.html

The BS EN ISO 6789:2017 torque standard recommends that torque tools should be calibrated every 12 months or every 5,000 operations of the tool, whichever comes earlier.

BS 7882:2017 recommends that for torque measuring devices, recalibrations should take place at least every 2 years to ensure the device is reading your torque values accurately and reliably.

Yes! The AWS Intelligent Instrumented Transducer Cable allows you to convert your current mV/V transducers from any manufacturer into truly intelligent digital transducers to be used with the AWS torque tool calibration machines.
