1. A device for conducting accelerated aging tests of a coating, the device comprising at least a first test chamber and a second test chamber which are separated by a mobile partition, each chamber being subjected to accelerated aging test parameters, comprising at least temperature and level of humidity, the test parameters being different between the first and second chambers and/or controllable independently between the first and second chambers, each of the first and second chambers additionally comprising a light to generate photo-oxidation, and the device also comprising a support for retention of at least one sample of the coating, the support being displaceable from the first chamber to the second chamber and conversely, after opening of the mobile partition between the first and second chambers in order to generate mechanical stresses by thermal shocks.
