Abstract

A sample (12) to be tested is placed on the base (10) of a hardness tester. Three vertical penetrators (1) penetrate the sample surface under the action of a weight (6) in a sliding support (7) mounted on a column (8). A spring loaded plate (13) holds the sample against the base when the test is performed and is lowered into position by a handwheel (9) on the sliding support. Average movement of the penetrators is indicated on a dial (5) mounted on the column and acting against a plate (2) with articulated joints to the penetrators.
