How do manufacturers test landscape chairs for resistance to mold, mildew, and other biological growths?
Manufacturers rigorously test landscape chairs for resistance to mold, mildew, and other biological growths to ensure durability and safety in outdoor environments. These tests typically involve exposing the chairs to high humidity, warm temperatures, and organic matter to simulate real-world conditions.
One common method is the ASTM G21 standard, which evaluates fungal resistance by inoculating materials with spores and monitoring growth over weeks. Accelerated weathering tests also replicate prolonged exposure to moisture and UV radiation, assessing how well coatings or materials inhibit biological growth.
Additionally, some manufacturers use salt spray tests or microbial challenge tests to verify resistance against algae and bacteria. Quality control often includes visual inspections, material sampling, and lab analysis to confirm long-term performance.
By combining these methods, manufacturers guarantee that landscape chairs remain mold-free and aesthetically pleasing, even in damp or shaded outdoor settings.
