A test to determine the hardness of metals and alloys by hydraulically pressing a steel ball into the metal and measuring the resulting indentation. The Brinell scale 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.
