PB7000 Brinell Hardness Tester

With automatic operation the 7000 Series Brinell Tester provides a lot of capability in a basic Brinell tester package. The tester uses a hydraulic load system delivered through a Belleville spring measurement system which accurately controls the load.

Brinell Hardness 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.
