Weathering test chambers are instruments used to evaluate the impact of weather (sun, rain, temperature variations…) on the physical and mechanical characteristics as well as the look of materials used outdoors faster than by regular outdoor exposure tests. This is achieved thanks to artificial and accelerated weathering tests, which simulate natural weathering. Controlled cycles of ultraviolet radiation, light, salt, electric arcs, water spray (simulating the rain effect), and heating elements are used to simulate the natural conditions of sun, rain and temperature changes.
Typical applications include textiles, automotive, paints and coatings, plastics and polymers, paper, chemicals.
