Brinnel and Rockwell tests are cLassified as macrohardness tests and they aie not suitable for brittle materials. The Bnnnel test is the one of oldest tests used for determining the hardness of materials and is directly related to proportional limit and the ultimate tensile strength of dental gold alloys. The convenience of the Rockwell test, with direct reading of the depth of the indentation, has lead to its wide usage. The Knoop hardness test is used to obtain the values for both exceedingly hard and soft materials. The hardness value is independent of the ductility of the material. The Vickers test is employed for dental costing gold alloys. It is suitable for determining the hardness of brittle materials.
The Knoop and Vickers tests are classified as microhardness tests. Both of these tests employ toads less than 9.8N.
The Shore and the Barcot tests are used for measuring the hardness of rubbers and plastics.
