Scratch resistance
A scratch hardness tester can be used to test the scratch resistance of a coated surface. A scribe stylus is pulled over a test piece with a previously defined constant force. With a "Yes/No test" it is finally tested whether the scribe penetrates the surface up to the substrate with this force or not. A test at a minimum load that penetrates a surface to the substrate is performed by increasing the scoring force.
