How are landscape tables tested for resistance to UV radiation and color fading?
Landscape tables, designed for outdoor use, undergo rigorous testing to evaluate their resistance to UV radiation and color fading. These tests ensure the furniture maintains its structural integrity and aesthetic appeal despite prolonged exposure to sunlight.
One common method is the accelerated weathering test, where tables are placed in specialized chambers simulating intense UV radiation, moisture, and temperature fluctuations. These chambers replicate years of sun exposure in just weeks or months, allowing manufacturers to assess durability quickly.
Another approach involves real-world exposure testing, where tables are placed in open environments with high solar intensity. Researchers monitor color changes and material degradation over time, comparing results to lab-based simulations.
For color fading, spectrophotometry measures subtle shifts in hue and saturation, ensuring the table’s finish remains consistent. Materials like powder-coated metals, UV-stabilized plastics, and treated woods are often tested to meet industry standards such as ASTM G154 or ISO 4892.
By combining lab and field tests, manufacturers guarantee landscape tables withstand UV rays and retain their vibrant colors, offering consumers reliable outdoor furniture.
