A device for conducting accelerated aging tests of a coating, notably an outer coating for an aircraft, in particular allowing the testing of the durability of the coating after having been subject to all kinds of stresses, is desired. An object of the disclosure thus relates to such a device including test chambers subject to different and/or independently controllable test parameters, and including light for generating photo-oxidation, the device including a support for a sample of the coating, displaceable between the chambers for generating mechanical stresses by thermal shocks. The disclosure herein finds applications in many fields of industry, and preferentially in the field of aeronautics.

Devices and methods for conducting accelerated aging tests of a coating with several types of stresses

The disclosed embodiments concerns a traction pad to be bonded for coating adhesion or surface cohesion tests by tearing including a counterbore designed to control the thickness of the adhesive film. Support elements such as wedges or a border maintain the base of the counterbore at the required distance from the tested surface and openings are provided for evacuating the adhesive prior to its controlled hardening when the traction pad is applied on the tested surface.
