Hardness Test Blocks / Indenters
The daily or periodic verification of the hardness testing machine by the user is an important point
on the way to a safe test result. In order to ensure perfect functioning of the hardness testing
system, an indirect check of the machine by means of calibrated reference materials, also called
hardness test blocks, is recommended to be carried out right before the daily use. In the indirect
test, all parameters of the hardness testing system (test force, measuring system, indenter) are
checked by the indentation on the calibrated reference material block. If the device is used only
once a week, the check should only take place on this day. In three-shift operation, a check at the
beginning of the shift is useful.
The hardness range of the hardness comparison plates should be selected so as to correspond as
closely as possible to the hardness of the material to be tested. Now, at least one indentation, but
more preferably several, is generated and evaluated. For example, damage to the indenter, and
other disturbancies are easily noticed before testing the actualmaterial.
