• Material Hardness

     · Even ceramic and composite material hardness measurements are possible. The most commonly used scales are "B" and "C". In Rockwell hardness test, prior to applying the testing load, a small minor load is applied to seat the indenter into the test piece and remove the effect of any surface irregularities. This provides better accuracy.
