"It is not as simple as a relationship to indentation hardness; a scratch incident is dynamic, whereas an indentation hardness test is static." Thus they considered the several types of loading that occur during a scratch test: compressive, shear, friction, and "traction" stresses, which are related to material fracture (for more information, see ANTEC[TM] 2007 technical paper "Relationship Between Surface Microstructure and Improved Scratch Whitening Resistance of Thermoplastic Polyolefins for Automotive Applications," by Hermel-Davidock, Seliskar, and Oelberg).

The indentation hardness of minerals is sufficiently characteristic to be used as a diagnostic tool; to measure it, a hard object under a known load is pressed into the surface of the substance to be tested.
The output of these hardness testers is typically a single indentation hardness value that is a measure of the relative penetration depth of the indentation tip into the sample.
