How do manufacturers test the resistance of landscape chairs to damage from sunscreen or lotions?

Manufacturers employ rigorous testing methods to evaluate the resistance of landscape chairs to damage caused by sunscreen and lotions. These tests are critical for ensuring the durability and longevity of outdoor furniture exposed to chemical-laden personal care products.

One common method involves applying standardized amounts of sunscreen or lotion to the chair's surface, simulating real-world usage. The products are left to sit for specified durations, often under controlled temperature and humidity conditions to mimic outdoor environments. After exposure, the material is inspected for discoloration, staining, or structural weakening.

Advanced testing may use accelerated aging techniques, where chairs undergo repeated cycles of product application, UV exposure, and cleaning. Manufacturers also conduct abrasion tests to assess how repeated contact with lotions affects the material's surface over time.

High-quality outdoor furniture often undergoes third-party certification testing, such as ASTM International standards, to validate resistance claims. These tests help manufacturers select the most suitable materials—such as UV-resistant polymers or treated fabrics—for products destined for poolside or beachside use.

By combining laboratory simulations with real-world performance data, manufacturers can design landscape chairs that maintain their appearance and structural integrity despite frequent exposure to sunscreens and lotions.
