The test is achieved by applying a known load to the surface of the tested material through a hardened steel ball of known diameter. It is desirable that the test load are limited to a impression diameter in the range of 2.5 to 4.75 mm.BHN - Brinell Hardness Number

What are the disadvantages of Brinell hardness test?What are the disadvantages of Brinell hardness test? Disadvantages of Brinell Hardness Test The main disadvantage of this test is that it is not suitable for small size objects due to large indentor impression. Slightly inaccurate hardness measurement while testing hard objects as ball indentor deforms. Not suitable for thin objects due to deep penetration. This test can only perform on the flat surfaces.

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 hardened steel ball as an indenter with a 3,000 kgf (29.42 kN; 6,614 lbf) force.
