- The test force is applied with an indenter of diamond quadrangular pyramid with a facing angle of 136 °. The definition of Micro Vickers Hardness value is the test force divided by the surface area of the indent after unloading.
- Formula：HV＝Test force（Kgf)/Surface area of the indent＝0.1891F/d2
Expression：704HV0.1/15 (Hardness value 704. Measured at a test force of 0.9807 N (100 gf) and a holding time of 15 s)
