Web(August 2024) The rubber compound, including the vulcanizing system, is shaped on the mill as 6–8 mm thick sheets. Round-shaped samples with 45 mm diameter are cut from the sheets. The samples are pierced in the middle in order to allow the rotor shaft to pass. Before the beginning of the measurement, the instrument is heated up to 118 degree C. 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. 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 can be used for all materials irrespective of h…
