Measuring at least 6 mm apart in different positions of the measurement hardness value 5 times, take the average (micro-porous materials are measuring at least 15 mm). In order to stabilize determination conditions, to enhance determination accuracy, hardness tester device should be in the same determination on supporting producer determination.
