What standards ensure UV protection in polyethylene outdoor bar stools?
Polyethylene outdoor bar stools are popular for their durability and weather resistance, but ensuring UV protection is critical for long-term use. Key standards include ASTM D4329, which tests plastic materials for UV exposure resistance, and ISO 4892, evaluating colorfastness and structural integrity under sunlight. High-quality polyethylene stools often incorporate UV stabilizers like carbon black or HALS (Hindered Amine Light Stabilizers) to prevent degradation. Additionally, certifications like the Blue Angel eco-label may indicate superior UV resistance. Choosing stools meeting these standards ensures fade resistance, extended lifespan, and reliable performance in sunny outdoor environments.
