How do ODM manufacturers test the fade resistance of outdoor furniture finishes?

Outdoor furniture must withstand harsh environmental conditions, especially prolonged exposure to sunlight. ODM manufacturers rigorously test the fade resistance of finishes to ensure durability and longevity. Common methods include accelerated UV exposure tests, where samples are placed in specialized chambers simulating years of sunlight in weeks. Weathering tests, such as salt spray and humidity cycles, further evaluate performance. Industry standards like ASTM G154 and ISO 4892 guide these procedures. Additionally, real-world outdoor testing provides practical insights. By combining lab and field data, ODM manufacturers guarantee that finishes retain color and integrity, meeting consumer expectations for quality outdoor furniture.
