-suitable for hardnees tests even under rough work shop conditions if large ball indenters and high test forces are used.
-suitable for hardnees tests on inhomogeneous materials because of the large test indentations,provided that the extent of the inhomogeneity is small in comparison to the test indentation.
-suitable for hardness tests on large blanks such as forged pieces , castings, hot-rolled or hot-pressed and heat-treated components.
-relatively little surface preparation is required if large ball indenters and high test forces are used.
-measurement is usually not affected by movement of the specimen in the direction in which the test force is acting.
-simple , robust and low-cost indenters
