Brinell Testers Operation: The Test Method

Widely used on castings and forgings, the Brinell test method applies a predetermined test force (F)
to a carbide ball of fixed diameter (D) which is held for a predetermined time and then removed. The
diameter (d) of the indentation width is measured twice - usually at right angles to each other and averaged.
A formula (see diagram) or chart (see links) is then used to convert the averaged measurements to a Brinell hardness number.

Test forces usually range from 500 to 3000 kilograms (occasionally down to 1kg in less frequently used
tests). Carbide* Brinell indenters are 10mm in diameter, although there are less frequently used tests
with light loads and smaller diameter indenters (from 5mm to 1mm). Generally, the Brinell tester load must be
held for 10 - 15 seconds although in practice shorter dwell times are often used if it is known not to
influence the test result. The Brinell test measurement is typically done to the nearest 0.05mm using
a standard 20X Brinell scope. This measurement is subject to operator influence.
