Test for the hardness of a substance
according to the area of indentation made by
a 10-mm/0.4-in hardened steel or sintered
tungsten carbide ball under standard loading
conditions in a test machine. The resulting
Brinell number is equal to the load (kg)
divided by the surface area (mm^2) and is
named after its inventor Johann Brinell.
