See also: Hardness. Brinell Hardness Number Brinell Scale. Brinell hardness test is one of indentation hardness tests, that has been developed for hardness testing. In Brinell tests, a hard, spherical indenter is forced under a specific load into the surface of the metal to be tested. The typical test uses a 10 mm (0.39 in) diameter Brinell Hardness - an overview | ScienceDirect TopicsDavid Mills, in Pneumatic Conveying Design Guide (Third Edition), 2016. Hardness. Hardness can be defined as the resistance of a material to an applied pressure or force. Brinell hardness. The Brinell hardness number is a number proportional to the load or test force of a hard steel ball to the calculated curved area of the indentation formed. The ball diameter is 1, 2.5, 5, or 10 mm.
