Rockwell hardness test . zwickroell.com The result of a Brinell method depends on the tested material .II. Theory and Principle of the Rockwell Hardness Test. The Rockwell Hardness Test uses a depth-differential method to test for hardness. A predetermined minor load is applied to the test sample, and the depth measurement is taken. Then a major load is applied to the same spot, which creates a deeper indentation.
