Testing and Calibrating

FAULTY TIGHTENING TORQUE HAZARD

An un-calibrated torque wrench can cause

screw connections, the torque wrench and

accessories to fail and produce faulty screw

connections. This might cause SERIOUS INJURY

or DEATH.

Always use tested and calibrated torque

wrenches ONLY. Always use tested torque

testing equipment ONLY.

Powerful forces are at work when using the

torque wrench. When torque wrenches are not

tested or not serviced there is a risk that they

will not bear the loads or will indicate faulty

tightening torques. ALWAYS take the following

safety information into account in order to

prevent SERIOUS INJURY or DEATH:

 ALWAYS test the accuracy of the torque

wrench with an approved torque tester

before use.

 NEVER use a faulty torque wrench.

 ALWAYS have the torque wrench

calibrated on a regular basis.

According to DIN EN ISO 6789 the minimum

calibration interval requirement for a torque wrench

is one year or 5000 load cycles (whichever case

occurs first). A firm's own specifications or quality

requirements for screwing applications can also

lead to considerably shorter calibration intervals.

WARNING

NEVER neglect recalibrating the torque wrench.

Improper calibration can cause the torque wrench

to be damaged.

Calibration should ONLY be implemented by

authorized specialists, an accredited calibration

laboratory or the manufacturer.

A calibration certificate as per DIN EN ISO 6789

comes with every new torque wrench. The torque

wrench and the calibration certificate are labeled

with the identical serial number.
