Abstract: In a method for evaluating mechanical tests of a coating on a substrate, in a first step a mechanical stress is applied onto the coating, in a second step the substrate having the coating is isothermally clamped, in a third step an infrared photograph is generated of the region in which the mechanical stress is applied onto the coating in the first step, and in a fourth step the infrared photograph is evaluated. A device is arranged for carrying out the method.

Abstract: A method is provided for detecting not fully set coatings and liquid or smearing impurities on a surface, in which in a first step a film is pressed onto a surface of a coating using a predefined press-on pressure, the film having a relative motion with respect to the surface of the coating, thereafter the film is pulled off the surface of the coating and finally it is determined whether impurities are adhering to the film. A device is also provided for performing the method, including at least one film, which may be pressed against a surface to be tested, at least one press-on roller having a surface by which the film is pressed against the coating, and at least one device for determining whether there are impurities adhering to the film.
