How do manufacturers test the resistance of landscape chairs to mold and mildew growth?
Manufacturers employ rigorous testing methods to evaluate the resistance of landscape chairs to mold and mildew growth, ensuring durability for outdoor use. One common approach involves exposing chairs to high-humidity environments, simulating real-world conditions where moisture promotes fungal growth. Accelerated aging tests may also be conducted, where chairs are subjected to cycles of wetness and warmth to observe mold development over time.
Some companies use specialized chambers that replicate tropical climates, monitoring how quickly mold spores colonize the chair materials. Additionally, antimicrobial coatings or treated fabrics are tested by inoculating surfaces with mold cultures and measuring inhibition rates. Standards like ASTM G21 provide guidelines for assessing fungal resistance in synthetic materials.
Beyond lab tests, outdoor field trials offer real-world insights, with chairs placed in shaded, damp locations for months. Manufacturers may also conduct abrasion tests to evaluate whether wear-and-tear compromises mold-resistant treatments. These comprehensive evaluations help ensure landscape chairs remain aesthetically pleasing and hygienic even in humid environments.
