What weathering tests simulate long-term aging of WPC outdoor bar stools?

To evaluate the long-term aging of WPC (Wood-Plastic Composite) outdoor bar stools, several weathering tests are employed to simulate years of exposure to environmental stressors. Key tests include:

1. UV Exposure Testing: Simulates sunlight degradation using UV lamps to assess color fading and material weakening.

2. Thermal Cycling: Alternates between extreme temperatures to test expansion, contraction, and structural integrity.

3. Moisture Resistance Testing: Evaluates water absorption and swelling by exposing stools to high humidity or immersion.

4. Salt Spray Testing: Mimics coastal conditions to check corrosion resistance of metal components.

5. Xenon Arc Testing: Combines UV, heat, and moisture for accelerated aging, replicating real-world outdoor conditions.

These tests ensure WPC bar stools maintain durability, aesthetics, and functionality over time, making them ideal for outdoor use.
