Modified Vickers hardness according to the UCI-
method (DIN 50159 and VDI/VDE Guideline
2616, Part 1). Measurement is done with test
load applied.
Diamond, Vickers pyramid angle 136°
Preferably metals, to which the alphaDUR mini
can be calibrated with standard hardness test
blocks. Tests on ceramics, glass and plastics are
also possible using comparison measurements
for calibration purposes.
10, 20, 30, 49 or 98 N, depending on the UCI
probe
Vickers (HV) 10 - approx. 3000
Conversion range see chapter 15
<2% to the value of the hardness test block
100 000 readings including date, time and
pass/fail evaluation.
Mean value, minimum, maximum and standard
deviation (absolute and relative). Single readings
can be deleted.
