Desert Site Outdoor or Natural WeatheringFor hot and dry desert conditions Sub-Tropical Testing Service established a facility in Surprise, Arizona located just west of Phoenix, Arizona. Weathering tests in the Arizona Desert have become regarded as an excellent location for durability studies. Higher annual solar irradiation and lack of humidity in the arid desert of Arizona can have a completely different effect than in other environments.
