TECHNICAL DATA
14 Technical Data
Test method
Modified Vickers hardness according to the UCI-
method (DIN 50159 and VDI/VDE Guideline
2616, Part 1). Measurement is done with test
load applied.
Indenter
Diamond, Vickers pyramid angle 136°
Test materials
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.
Test load
10, 20, 30, 49 or 98 N, depending on the UCI
probe
