Indentation hardness - Wikipedia
Indentation hardness tests are used in mechanical engineering to determine the hardness of a material to deformation. Several such tests exist, wherein the examined material is indented until an impression is formed; these tests can be performed on a macroscopic or microscopic scale. When testing metals, indentation hardness correlates roughly ...

piece with a hardened steel ball indenter typically 10mm in diameter. The hardness number is determined by measuring the diameter of the indentation using a simple magnifier with an eyepiece containing a graduated scale. The hardness value is calculated by dividing the load by the surface area of the indent.

Brinell scale - Wikipedia
The standard format for specifying tests can be seen in the example "HBW 10/3000". "HBW" means that a tungsten carbide (from the chemical symbol for tungsten or from the Spanish/Swedish/German name for tungsten, "Wolfram") ball indenter was used, as opposed to "HBS", which means a hardened steel ball. The "10" is the ball diameter in millimeters.
