The measurement of micro-hardness with loads between 0.09807 N and 0.9807 N has been carried out in direct mode (appraiser measured the dimensions of indentations with a measuring device fitted to the micro-hardness tester, a part of microscope) and in modified remote modes. The reference block -- certified reference material with defined specified hardness and its uncertainty was used as a specimen, particular measurement involved indirect calibration of tester. The influence of applied load on the measured value of micro-hardness was evaluated by Meyer's index n and PSR method. The difference between values obtained by particular modes is statistically significant. [ABSTRACT FROM AUTHOR] |
