description	An automated laboratory apparatus for dynamically testing the durability of a coating is provided. The apparatus includes an actuator that drives at least one test unit. Each test unit includes a pressure chamber assembly having a main body and a clamping member. The main body includes a monitoring window, an opening, and an inner chamber wall defining a pressure chamber within the main body. The clamping member includes a central opening. The clamping member and main body are adapted to sandwich a substrate including the coating therebetween to close the pressure chamber. A driven member extends through the central opening in the clamping member and is contactable with the substrate. The actuator drives one or both of an oscillating linear and an oscillating rocking motion of the driven member. A method of testing the durability of a tire coated with a self-sealing sealant for leak-proof performance is also provided. La présente invention concerne un appareil de laboratoire automatisé pour tester dynamiquement la durabilité d'un revêtement. L'appareil inclut un actionneur qui entraîne au moins une unité de test. Chaque unité de test inclut un ensemble chambre de pression ayant un corps principal et un élément de serrage. Le corps principal inclut une fenêtre de surveillance, une ouverture et une paroi de chambre interne définissant une chambre de pression à l'intérieur du corps principal. L'élément de serrage inclut une ouverture centrale. L'élément de serrage et le corps principal sont conçus pour prendre en sandwich un substrat incluant le revêtement entre eux pour fermer la chambre de pression. Un élément entraîné s'étend à travers l'ouverture centrale dans l'élément de serrage et peut être mis en contact avec le substrat. L'actionneur entraîne l'un ou les deux parmi un mouvement oscillant linéaire et un mouvement oscillant de balancier de l'élément entraîné. L'invention concerne également un procédé de test de la durabilité d'un pneu revêtu d'un agent d'étanchéité auto-obturant pour déterminer une performance anti-fuite.
