 The Knoop Hardness test is good for testing plating or thin sheets. It uses a pyramid shaped diamond that makes a very small indentation. It's often used for foils but works well for plating as well.

 We use a micro-hardness tester for our research. Most hardness tester manufacturers that I talked to initially were not familiar with this type of testing but we found that LECO were able to step up with the right instrument.
This uses the Vickers or Knoop method both of which are selectable and only require slightly different indentation head.
