Measuring a coating’s hardness using the indentation method, the
Elcometer 3095 Buchholz Hardness Tester consists of a bevelled disc indenting tool which is fitted into a stainless steel block exerting a constant test load of 500g (17.6oz).
The gauge is placed on to the coating and then removed after 30 seconds. The length of any subsequent indentation in the coating is measured using the graduated microscope.
The result is expressed as units of Buchholz Indentation Resistance using the scale provided.

One method is the indentation method, using the Elcometer 3095 Buchholz Hardness Tester; where a known downward force is applied to a formed shape for a predefined timeframe, and the amount of indentation left in the coating is measured.
