SCREWDRIVERS AND TORQUE WRENCHES

ISO 6789:2017

How does it affect a torque tool user?
If a current end user was previously content to buy a new torque tool and put it into service on the basis of the calibration
certificate supplied with the tool by the manufacturer, then they can continue to do so after the standard changes, even though the
new piece of paper is now called a declaration of conformance.
If the end user’s quality control processes currently require a traceable calibration certificate issued by an accredited laboratory
then they will already not accept the current manufacturer’s document but will be paying for a calibration in an accredited
laboratory�
If the end user is currently happy with the manufacturer’s document for a new tool, then a periodic assessment from their
in-house facility or from a sub-contractor should provide an equivalent level of confidence in the performance of the tool. Under
the new Part 1 these sub-contractors will be able to continue that work as long as they observe the new changes, but they will
not be able to call it a calibration and will not be able to issue a calibration certificate. They will be able to issue a declaration of
conformance.
In essence, one of the key changes in the standard is to protect
the use of the term calibration. It will initially be confusing to
both end users and service providers, but the International
Standards Organisation has clear definitions of words such as
calibration and we will have to adapt our thinking to conform.

Torque Wrench Calibrator (TWC)
To help our customers meet the requirements of this new
standard we have launched the TWC Auto which enables
torque wrench calibration or testing in accordance with ISO
6789-2:2017. Further details can be found on page 111.
