The Brinell hardness test is a method used to measure the hardness of materials, particularly metals and alloys. It involves pressing a hard spherical indenter into the material under a specific load and measuring the diameter of the resulting indentation.
In the Brinell hardness test, an optical method, the size of indentation left by the indenter is measured. In contrast to the optical Vickers method, in which a pyramid-shaped indenter is pressed into a specimen, the Brinell method uses a spherical indenter.

The Brinell scale / b r ə ˈ n ɛ l / characterizes the indentation hardness of materials through the scale of penetration of an indenter, loaded on a material test-piece. It is one of several definitions of hardness in materials science.
Brinell test procedure. In the Brinell hardness test, an optical method, the size of indentation left by the indenter is measured. In contrast to the likewise optical Vickers method,which involves a pyramid-shaped indenter being pressed into a specimen, the Brinell method uses a spherical indenter.
