The transfer torque wrench is used as a transfer standard for calibrating torque
wrench calibrating devices.
Generally, when a torque wrench calibrating device is used, torque is gener­
ated by exerting force on the lever of the torque wrench to be calibrated (e.g.
the triggering torque wrench to be used in the workshop). When calibrating the
torque wrench calibrating device, on the other hand, a transfer torque wrench
(the indicating torque wrench) is inserted into the calibrating device instead of a
torque wrench in need of calibration. The torque is generated in the same way
as for normal use, so that the measurement conditions for the calibrating
device are identical. This is of particular importance with respect to the para­
sitic loads acting at the same time as the actual calibration torque, namely lat­
eral force and bending moment.
The design of the TTS transfer torque wrench is adapted to German Calibra­
tion Service guideline DKD‐R 3‐8
wrench calibrating devices.
To conform to the strict requirements regarding the traceability of a transfer
standard, a transfer torque wrench must be calibrated in an accredited calibra­
tion laboratory (in Germany, this is a DKD laboratory). The DKD calibration
certificate in accordance with guideline DKD‐R 3‐7
