How do manufacturers test landscape tables for resistance to UV radiation and fading?

Manufacturers rigorously test landscape tables for UV resistance and fading to ensure they withstand prolonged sun exposure without degrading. Here’s how they do it:

1. Accelerated UV Testing Chambers: Tables are placed in specialized chambers that simulate intense sunlight using UV lamps. These chambers replicate years of sun exposure in weeks or months, allowing manufacturers to assess fading and material degradation quickly.

2. Xenon Arc Testing: This method uses xenon arc lamps to mimic full-spectrum sunlight, including UV, visible, and infrared light. It evaluates not just color fading but also structural integrity under cyclic weather conditions.

3. Outdoor Real-World Exposure: Some manufacturers place tables in high-sunlight regions (e.g., Arizona or Florida) for extended periods. This real-world testing provides data on how colors and materials perform over time.

4. Spectrophotometer Analysis: After exposure, devices measure color changes precisely, comparing results to industry standards (e.g., ASTM G154 or ISO 4892) to rate UV resistance.

5. Material-Specific Protocols: UV-stabilized plastics, powder-coated metals, and treated woods undergo tailored tests. For example, HDPE tables are evaluated for chalkiness, while metals are checked for coating adhesion.

By combining these methods, manufacturers ensure landscape tables remain vibrant and durable, even in harsh outdoor environments.
