5.10.1 Checking the fasteners of stud anchors
To ensure that the specified pretension as per the approval / operating
instructions has been correctly applied when the "Adaptive" operating
mode is used to tighten stud anchors, the first stud anchor and the
last stud anchor always have to be checked with a calibrated torque
wrench. This check of the applied installation torque has to be carried
out immediately after tightening (installation) of the stud anchor.
The check torque to be applied corresponds to the installation torque
specified for the stud anchor in question; obtain this information from
the instructions for use for this anchor issued by the stud anchor
manufacturer.
