The Vickers hardness test was developed in 1921 by Robert L. Smith and George E. Sandland at Vickers Ltd as an alternative to the Brinell method to measure the hardness of materials. [1] The Vickers test is often easier to use than other hardness tests since the required calculations are independent of the size of the indenter, and the indenter .This article discusses the 9 sand test types methods and equipment used in the foundry to test moulding sand with the proper formula, diagrams, summary, PPT and animation. The list of moulding sand testing methods is as follows: Permeability test. Hardness test. Moisture content test. Clay content test. Grain fineness number (GFN). 5.3 Because microindentation hardness tests will reveal hardness variations that commonly exist within most materials, a single test value may not be representative of the bulk hardness. Vickers tests at 1000 gf can be utilized for determination of the bulk hardness, but, as for any hardness test, it is recommended that a number of indents are made and the average .
