4.4.1 About the Indent Depth Brinell Hardness Test (HBT)
The indent depth Brinell hardness test is a combination of the indenter and the test force used in the
Brinellhardnesstest.ThistestmethodcalculatestheBrinellhardnessfromthedi󰀨erenceofthedepth
before and after applying the preliminary test force of the Rockwell hardness test method.
Therefore,performthetestaftercalibratingusingtestblockswithdi󰀨erent,knownBrinellhardness
values as a reference.
