Abstract: A testing device for checking the quality of a paint or lacquer layer includes at least one friction element moving device. To prevent an impression on a test region, the friction element moving device is configured to (i) initially move at least one friction element in frictional contact along a defined path, e.g., a circular path, over a test region of a paint or lacquer layer, and (ii) subsequently eliminate the frictional contact between the friction element and the test region during the movement of the friction element.

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: An automated laboratory system, which includes a vessel supply rack for supplying vessels in a vessel supply position, a movable vessel pick-up table for picking up and moving a vessel from the vessel supply position to the vessel filling position, a movable metering table disposed above the vessel pick-up table and configured for picking up and moving at least two metering containers configured to hold chemical substances, the metering containers being able to be positioned above the vessel filling position to fill chemical substances into a vessel, a scale, disposed underneath the vessel filling position for determining a substance quantity filled into a vessel, and a stirrer, disposed above the vessel filling position, for mixing of substances filled into a vessel. Also described is a method for operating such a laboratory system.

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.

Abstract: A method and a device for inspecting surface coatings on workpieces, in particular of lacquer coatings, using an image capture and/or image processing system. The image capture and/or image processing system is designed to measure and/or process electromagnetic radiation from surface coating and/or a layer beneath it which is at least partially outside of the visible wavelength range.
