Demo test result

2014-10-29 (2.7 μm) 2458 HV with 0.3 μm maxpenetration at 40 mN

2014-11-3 (11 μm) 2645 HV with 0.4 μm maxpenetration at 80 mN

Remark Based on theoretical calculationin Instrumented Indentation TestASTM E2546.

Provides hardness vs load graphthat enables penetration point to

be determined.

Not based on indent diameter measurement, no image acquisition.

Need to adjust IIT hardness valueto optical method hardness value(using software).
