| Brinell hardness number | A number related to the size of the permanent impression made by a ball indenter of specified size (usually 10 mm in diameter) pressed into the surface of the material under a specified load: where P = applied load in kg, D = diameter of the ball in mm, and d = diameter of the impression in mm. (05 Mar 2000) |
| Brinell hardness number |
A measure of hardness determined by the Brinell Hardness test, in which a hard steel ball under a specific load is forced into the surface of the test material. The number is derived by dividing the applied load by the surface area of the resulting impression.

| Brinell hardness n. |
a number indicative of the degree of relative hardness of a material, calculated after measuring the diameter of the impression made by a steel ball pressed under a known load into the surface of the material being tested; equal to the load in kilograms divided by the surface area of the indentation in square millimeters.
