How do manufacturers test the resistance of landscape chairs to prolonged exposure to direct sunlight?
Manufacturers rigorously test the resistance of landscape chairs to prolonged sunlight exposure to ensure durability and longevity. One common method involves accelerated weathering tests, where chairs are placed in specialized chambers that simulate intense UV radiation, high temperatures, and humidity cycles. These chambers replicate years of sunlight exposure in just weeks or months.
Another approach is real-world outdoor testing, where chairs are placed in high-sunlight locations for extended periods. Manufacturers monitor color fading, material cracking, and structural integrity over time. They also use spectrophotometers to measure color changes and tensile strength tests to assess material degradation.
Advanced labs may employ xenon-arc lamps, which closely mimic natural sunlight, to evaluate UV resistance. Data from these tests helps manufacturers select the best materials—such as UV-stabilized plastics, powder-coated metals, or treated woods—for long-lasting outdoor furniture. By combining lab and field tests, they ensure landscape chairs withstand years of direct sunlight without compromising quality.
