Brinell Hardness Test. The Brinell hardness test entails measuring the diameter of indentation caused by a constant concentrated force applied by a steel or carbide spherical indenter on a test specimen. The steel ball indenter is first placed in contact with the material before a constant force is applied and maintained for a 10 to 15 second duration, known as the .The Vickers hardness test is ideal for testing of all metals and is therefore the method with the widest range of application.
