A method for testing a thermography apparatus, the thermography apparatus being designed for carrying out a thermography method, the method for testing being employed to test the thermography apparatus for its correct operation with a view to the detection of delaminations, the method for testing comprising:
- employing a test component comprising a delamination introduced deliberately into the coating system with defined properties in at least one defined region of the test component, and
- detecting the at least one defined delamination of the coating system on the test component by using the thermography method employed in the thermography apparatus.
