Thus, water hardness is usually reported as milligrams of calcium carbonate per liter of solution. The U.S. Geological Survey (www.usgs.gov) provides the following general guidelines for classification of waters: Soft: 0 to 60 mg/L hardness as CaCO 3 Moderately hard: 61 to 120 mg/L hardness as CaCO 3 Hard: 121 to 180 mg/L hardness as CaCO 3VICKERS HARDNESS TEST: The Vickers hardness test uses a square base diamond pyramid as the indenter. The included angle between the opposite faces of the pyramid is l36°. The Vickers hardness tester operates on the same basic principle as the Brinell tester, the numbers being expressed in the terms of load and area of the impression.Specimens of various metals (aluminium, brass, copper, high speed steel in this experiment) Indenters Rockwell hardness testing machine (b)Theory There are many de nitions for hardness depending on the material. For metals, the most appropriate one would be ‘resistance to permanent deformation’. Hardness can be
