Corrosion resistance testing for urban outdoor furniture involves exposing materials to specific chemical reagents that simulate harsh environmental conditions. Common reagents include sodium chloride (NaCl) for salt spray tests, which evaluates resistance to saline environments like coastal areas. Sulfuric acid (H2SO4) and acetic acid (CH3COOH) are used in acid rain simulations, replicating urban pollution effects. Additionally, copper-accelerated acetic acid salt spray (CASS) tests may employ copper chloride (CuCl2) to assess accelerated corrosion. These tests follow standards such as ASTM B117 and ISO 9227, ensuring furniture durability against corrosion from moisture, salts, and pollutants. The results help manufacturers select materials like stainless steel, aluminum, or treated woods that withstand long-term outdoor exposure, maintaining safety and aesthetics in public spaces.
