3.2 Preparation of the sample
Unsuitable material samples can cause measuring errors. Therefore, test preparation
and execution should be carried out according to the sample properties. The
preparation of the sample and its surface should meet these basic requirements
:
During the surface preparation of the sample, its surface should not be exposed to
thermal cooling or heating.
The test surface should be flat and have a metallic gloss. There must be no oxide
layers or other contamination
