What are the most common UV resistance tests performed on the Landscape Square table?

To ensure the longevity and aesthetic appeal of Landscape Square tables in outdoor settings, several standardized UV resistance tests are commonly performed. These evaluations simulate prolonged sun exposure to predict material performance.

The most prevalent test is the Xenon Arc Exposure, which replicates full sunlight spectrum including UV, visible, and infrared light. This accelerated weathering test, following standards like ASTM G155 or ISO 4892-2, rapidly assesses color fading, chalking, and gloss loss.

Equally important is the QUV Accelerated Weathering Test using fluorescent UV lamps. This method, standardized under ASTM G154, focuses specifically on UV degradation by cycling between UV exposure and condensation. It effectively reveals cracking, brittleness, and color change in table materials.

Industry professionals frequently conduct Color Fastness Testing using spectrophotometers to measure Delta E values. This quantifies color deviation after UV exposure, with higher values indicating greater fading. Many manufacturers supplement these with Outdoor Real-Time Weathering studies in high UV index locations, providing correlation data for accelerated tests.

These comprehensive evaluations help manufacturers select appropriate UV stabilizers, coatings, and materials—ensuring Landscape Square tables maintain structural integrity and visual appeal despite continuous solar exposure.
