WEATHERING MATERIALS IN SOUTH FLORIDA SINCE 1928 Position Average Yearly Solar Radiation at an incidence angle of 5º South: Average Relative Humidity Average Ambient Temperature Average Yearly

Hialeah is located in the Miami Area. Samples are exposed under the hot, humid and Sunny climate typically experienced in south Florida.

2 WEATHERING MATERIALS IN SOUTH FLORIDA SINCE 1928 Position Average Yearly Solar Radiation at an incidence angle of 5º South: Average Relative Humidity Average Ambient Temperature Average Yearly Rainfall: 25º 51 N, 80º18 W 6182MJ/m² 84% 24ºC 1650mm ISO/IEC A2LA Accredited DuPont has run outdoor weathering tests in Hialeah, Florida since 1928, almost 85 years. Hialeah is located in the Miami Area. Samples are exposed under the hot, humid and Sunny climate typically experienced in south Florida. The tip of the Florida peninsula is considered a benchmark climate and the Gold Standard for outdoor weathering tests. Exposures can be performed on virtually anything: finished products, materials, or even raw materials - anything that requires high performance in outdoor environments, such as garden products, automotive coatings, as well as interiors, banners, flags, patio furniture, pond liners, pool covers and construction materials. These tests may be used for new product development and qualification, warranty certification, liability protection or competitive benchmarking.

OUTDOOR WEATHERING EXPOSURE APPLICATIONS All outdoor exposures meet the requirements of ASTM G7 Standard Practice for Outdoor Exposure of Organic Materials unless otherwise specified Open Back

4 OUTDOOR WEATHERING EXPOSURE APPLICATIONS All outdoor exposures meet the requirements of ASTM G7 Standard Practice for Outdoor Exposure of Organic Materials unless otherwise specified Open Back Exposure: Samples exposed on adjustable standard aluminum racks. Flexible samples can be backed with expanded metal for support without influencing sample temperature. Commonly used angles: Application Angle Textile Architectural Automotive Fenestration & Siding Custom angles to 90. Black Box Exposure: The sample is mounted on a rack, which is backed by a matblack painted aluminum box. Sunlight heats the air trapped inside the box, raising the temperature of the samples during the day. The black box can be angled according to customer requirements but is most commonly used at 5 degrees to the horizontal. This test is primarily used for automotive coatings, and other coatings that have to withstand a high-temperature end-use environment. All exposure angles are available as requested. Backed Exposure: Samples exposed on adjustable standard aluminum racks with a backing of untreated plywood The backing produces a higher temperature-testing environment that may be more representative of in use conditions Degrees Farenheit Surface Temperature of Exposure Panels Clear Sky at Noon 0 Blue White Red Black Sample Colour Black Box Insulated Back Open Back

BEHIND GLASS WEATHERING EXPOSURE APPLICATIONS All under glass outdoor exposures meet the requirements of ASTM G24 Standard Practice for Outdoor Exposure of Organic Materials unless otherwise

This type of test is used for products with indoor end-use environments such as draperies, upholstery fabric and interior automobile trim. ASTM G24 specifies single strength window glass.

5 BEHIND GLASS WEATHERING EXPOSURE APPLICATIONS All under glass outdoor exposures meet the requirements of ASTM G24 Standard Practice for Outdoor Exposure of Organic Materials unless otherwise specified. Exposure Behind Glass: Samples on adjustable standard aluminum racks or on a black box are exposed behind a layer of glass. This type of test is used for products with indoor end-use environments such as draperies, upholstery fabric and interior automobile trim. ASTM G24 specifies single strength window glass. Other standards often require special glasses that are appropriate for simulation of the end-use environment, such as automotive windshield glass. All angles and backings are available.

Entire component testing is designed to take these variables into account.
