FAQ

How should I apply impact angle correction to my rebound hammer test result?
Here it is necessary to differentiate between classical rebound hammers (R-value) and the Silver Schmidt hammers (Q-value). Classical rebound hammers require an impact angle correction when the impact is not carried out horizontally. For the Original Schmidt, the correction can be found in the manual for vertically up and vertically down measurements. The Original Schmidt OS8000 applies a more advanced impact angle correction automatically for any angle. On the app, the user can see both the uncorrected and the corrected values. The Silver Schmidt hammers are intrinsically impact angle independent so no correction is necessary.
