Requirements for the sample ..................................................................................................... 8
6.1.1
The surface temperature of the sample should be less than 120 °C. ............................................ 8
6.1.2
The sample must feature a metallic smooth, ground surface, in order to eliminate erroneous
measurements brought about by coarse grinding or lathe scoring. The roughness of the finished surface
should not exceed 2 µm. .............................................................................................................................. 8
