Aftertheimpactdevicehasbeenusedfor1000‐‐2000times,pleaseusethe
nylon brush provided to clean the guide tube and impact body. When
cleaningtheguidetube,unscrewthesupportringfirst,thentake out the
impactbody, spiral the nylonbrushincounter‐clockwisedirectionintothe
bottom of guide tube and repeat a few times to remove any dust or small

3.2ImpactDeviceSelection
RefertoAppendixTable1andTable3forselectionofimpactde v i c e .
Note：For Verification, Take 5 tests around the test block and get
your average. This average value should be within the acceptable
tolerance of the test block value. If this value exceeds the
allowable tolerance of the test block, a calibration should be
performed. See above.

3.3PreparationoftheSampleSurface
Preparation for sample surface should conform to the relative requirement in
AppendixTable3.
Test surfaces should be at or close to room temperature for optimal
performance
