Test apparatus for testing hard material containing friction-increasing paint layer, comprises test piece carrier, on which test piece is mounted such that test surface of test piece is temporarily pressed against paint layer

摘要

The test apparatus (1) comprises a test piece carrier (5) for receiving a test piece (17) with a test surface (18). The test piece is mounted to the test piece carrier, such that the test surface of the test piece is temporarily pressed against the paint layer (2) in the operating state of the test apparatus. The test piece comprises a material in the area of the test surface, which is scratched when in contact with the hard material particles contained in the paint layer. An independent claim is included for a method for testing a hard material containing friction-increasing paint layer.
