Urban outdoor composite furniture must withstand harsh environmental conditions, including UV radiation, rain, temperature fluctuations, and pollution. To ensure long-term durability and safety, manufacturers rely on standardized aging resistance tests. Key international standards include ASTM D2565, which specifies methods for xenon-arc exposure to simulate sunlight and rain, and ISO 4892, covering various accelerated weathering techniques using light and water. The EN 15534 series provides European guidelines for wood-polymer composites, focusing on mechanical property retention after aging. These tests evaluate color stability, surface cracking, loss of gloss, and structural integrity. Compliance helps guarantee that furniture maintains performance and aesthetics over years of outdoor use, reducing waste and ensuring public safety.
