Laboratory’s Hardness Testing Capabilities

Materials can have different degrees of hardness and this can affect properties like friction and wear characteristics during use.  The laboratory has a range of hardness testing instrumentation to evaluate metals, plastics, rubbers and certain coatings depending on their thickness.

Two types of hardness testing equipment for metals and alloys are available:-Shore A Hardness tester for plastics

Hardness testing can be used a fast and cost effective alternative to tensile testing. A hardness test can be used to estimate the ultimate tensile strength UTS of steels. This approach is not valid for non ferrous materials though.

For rubbers, plastics and some polymeric coatings two other tests are available:

  • Shore A and Shore D durometers can be used for measuring plastics and rubbers.

Rockwell hardness tester Vickers hardness tester

Typical Applications of Hardness Testing

  • Measuring the hardness of tool steels
  • Measuring the hardness of bearing materials
  • Shore hardness for rubbers and plastics.
