The aging resistance test for urban outdoor composite furniture materials simulates harsh environmental conditions to evaluate durability and longevity. Key factors include prolonged UV exposure, which tests color stability and surface degradation; temperature fluctuations from sub-zero to extreme heat, assessing thermal expansion and contraction; moisture and humidity cycles, evaluating water absorption and mold resistance; and cyclic weathering that combines these elements to replicate real-world stress. Tests often use accelerated weathering chambers that control irradiance, temperature, and spray cycles. Standards like ASTM G154 or ISO 4892 provide guidelines, ensuring materials withstand urban outdoor environments, including pollution and mechanical wear, without significant loss of integrity or appearance.
