TIV is a portable test instrument for optical
hardness testing according to Vickers
under test load (Fig. 11). An optical
system including a CCD camera enables
viewing “through the diamond” (Through-
Indenter-Viewing). For the first time this
new method makes it possible to directly
watch the process of the Vickers diamond
penetrating the test material on the display.
The TIV technique can be used to carry
out a hardness test without any additional
calibration on different materials thanks
to the optical method of measurement.
Moreover, the static test load application
also makes it possible to carry out measurements
on both thin and small objects,
as well as on coatings.
