Abstract
Depth sensing hardness measurements have been performed in a round robin test on metallic alloys and glass with different degrees of surface roughness. The standard deviation of the penetration depths has been determined for fixed load values between 0.05 N and 87.1 N, respectively, and analyzed dependent upon the arithmetic roughness. The contribution of the roughness to the depth sensing hardness can be shown as follows: The standard deviation of the Depth Sensing Hardness Value will be lower than 10 % if the penetration depth is more than twentyfold of the arithmetic mean roughness. This simple rule yields nearly independent of the material investigated in this work.
