The Vickers hardness test, an offshoot of the venerable Brinell test, has been used since the early 1920s. Although the concept of using one test method to cover a wide range of materials hasn't changed much in the last 90 years, upgrades to the equipment used to perform the test have ...

A first memory (82) stores the function HV = (x<2> (Ax<2> + Bx + C))<-1>, where x = df/fo, HV is the (Vickers) hardness value to be measured, fo is the fundamental frequency (natural frequency) of the free resonator and df the deviation of the fequency of the resonator ...
the material must be prepped and polished much more than other tests. Using the optical system makes it a more expensive and slower working machine than the Rockwell or Brinell testers. The level of accuracy provided by the Vickers Hardness Test is not needed for every application. So, it’s...
