hardness number

A number on a calibrated scale indicating the relative hardness as determined by a particular system of testing, e.g., Knoop, Mohs, Rockwell, Vickers hardness tests. A steel ball or diamond point is applied with a known variable load for a determined period of time to produce an indent whose depth or diameter can be measured.
