Overview
The Brinell scale characterizes the indentation hardness of materials through the scale of penetration of an indenter, loaded on a material test-piece.
💡
Pro Tips
Load (P) is typically measured in kilogram-force (kgf).
Ball diameter (D) and indentation diameter (d) are in millimeters (mm).
The indentation diameter must be smaller than the ball diameter.

Fun Facts
"The Brinell test was the first widely used and standardized hardness test in engineering."
"It was proposed by Swedish engineer Johan August Brinell in 1900."
"The test uses a heavy load (up to 3,000 kgf) and a 10 mm diameter carbide or steel ball."
