Today the so-called dynamic micro hardness with analysis of the force indentation function is replacing in many cases the conventional Vickers hardness measurement for evaluating the hardness of thin films such as coatings for wear protection with thicknesses in the range of several micrometers. This test procedure requires equipment with a numerically controlled loading unit and a high resolution mesurement of the indentation depth. This contribution shows, using various different examples, that the load indentation measurement can solve problems such as the influence of the operator, but the test conditions should be well selected to give comparable and meaningful results. Therefore, this paper analyzes the most important reasons for deviations in practice, and makes suggestions for a standardized test procedure and test documentation.
