It was decided that the indenter shape should be capable of producing geometrically similar impressions, irrespective of size; the impression should have well-defined points of measurement; and the indenter should have high resistance to self-deformation. Currently some watch companies are improving the crystal watch glass by testing aastm strength using the Vickers hardness test.

Start Webshop Product catalog Aatm presentation. This standard is issued under the fixed designation E; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.

The hardness number is determined by the load over the surface area of the indentation and not the area normal to the force, and is therefore not pressure.

Awtm hardness number can be converted into units of pascalsbut should not be confused with pressure, which also has units of pascals. The pyramidal diamond indenter of a Vickers hardness tester. As a rule of thumb the sample thickness should be kept greater than 2.
