The Vickers hardness test method, also referred to as a microhardness test method (ASTM E-384, E92 and ISO 6507), consists of indenting the test material with a diamond indenter. This indenter has the form of a pyramid with a square base and an an...

As defined in ISO 6508 & ASTM E-18, the Rockwell test is the most commonly used hardness test method. It is generally easier to perform, and quicker than other types of hardness testing methods.
The Rockwell method measures the permanent...

Most commonly used to test materials that have a structure that is too coarse or that have a surface that is too rough to be tested using another test method, e.g., castings and forgings. Brinell testing often use a very high test load (3000 Kgf) ...

Universal hardness testers are in fact hybrid instruments allowing the user to make Rockwell, Vickers and Brinell hardness tests according to the applicable ISO, ASTM and JIS standards, with one single machine.
Universal hardness testers do ...
