Brinell scale is a measure of indentation hardness of materials based on the size of penetration of an indenter. Learn about its history, test details, common values, and comparison with other hardness scales.
Skala twardości Brinella – skala oznaczania twardości metali na podstawie testu dokonanego metodą opracowaną przez szwedzkiego inżyniera Johana Augusta Brinella w 1900 roku. Twardość w skali Brinella oznacza się HBW [1] i leży w zakresie od 3 do 650.
Learn how to measure the hardness of a material using the Brinell Hardness Test method, which involves applying a force to a spherical indenter and measuring the indentation size. Find out the formula, the unit, the advantages, and the standards of this test method.

The Brinell hardness test consists of applying a constant load, usually in the range 500–3000 N, for a specified period of time (10–30 s) using a 5 or 10 mm diameter hardened steel or tungsten carbide ball on the flat surface of a work piece. The Brinell hardness number (HB) is then obtained as: (1)
