Introduction About Application Equipment Find out more DEFINITION OF THE VICKERS HARDNESS TEST The Vickers hardness test is a versatile hardness test method, used for both macro and micro hardness testing. It has a broad load range, and is suitable for a wide range of applications and materials.The Brinell hardness test was developed by Swedish engineer Johan August Brinell in 1900. The Rockwell hardness test was invented in the 20th century by Stanley P. Rockwell, and later refined by Hugh M. Rockwell. The Vickers hardness test, meanwhile, was developed at Vickers Ltd in the United Kingdom in 1921.
