The Rockwell hardness test is the most used and versatile of the hardness tests. For soft materials such as copper alloys, soft steel, and aluminum alloys a 1/16 diameter steel ball is used with a 100-kilogram load and the hardness is read on the B scale.
The hardness of plastics is most commonly measured by the ShoreÂ® (Durometer) test or Rockwell hardness test. Both methods measure the resistance of plastics toward indentation and provide an empirical hardness value that doesn't necessarily correlate well to other properties or fundamental characteristics.
