Brinell test procedure – Hardness Know-How

The larger the indent left in the surface of a workpiece (specimen) by the Brinell indenter with a defined ball diameter and a defined test force, the softer the tested material. In order to determine the Brinell hardness (HBW) according to ISO 6506, the spherical, hard metal (tungsten carbide) indenter is pressed into a specimen (workpiece) with a defined test load (between 1 kgf and 3000 kgf).
