Fundamentals of Rockwell Hardness Testing
Fundamentals of Rockwell Hardness Testing Like the Brinell, Vickers, Knoop, Scleroscope and Leeb tests - all of which fall in the general category of indentation hardness tests - the Rockwell test is a measure of the resistance of material, specifically metals, to permanent indentation. Indentation hardness is not a fundamental property of a ...
Material hardness and hardness testing | ispatguru.com
The Rockwell hardness testing machine to measure the hardness of metal measures resistance to penetration like the Brinell test, but in this case, the depth of the impression is measured rather than the diametric area. With the Rockwell testing machine, the hardness is indicated directly on the scale attached to the machine.

Vickers hardness test - Wikipedia
The Vickers hardness test was developed in 1921 by Robert L. Smith and George E. Sandland at Vickers Ltd as an alternative to the Brinell method to measure the hardness of materials. The Vickers test is often easier to use than other hardness tests since the required calculations are independent of the size of the indenter, and the indenter can be used for all materials irrespective of hardness.
