How do ODM manufacturers test the resistance of outdoor furniture to acid rain?

Outdoor furniture must withstand harsh environmental conditions, including acid rain, which can cause corrosion and deterioration over time. ODM manufacturers employ rigorous testing methods to ensure their products meet high durability standards.

One common approach is accelerated weathering tests, where furniture materials are exposed to simulated acid rain in controlled laboratory conditions. These tests replicate the chemical composition of acid rain, typically using diluted sulfuric and nitric acid solutions. The furniture undergoes repeated cycles of wetting and drying to mimic real-world exposure.

Another method involves salt spray testing, which evaluates corrosion resistance by exposing materials to a saline mist. While not identical to acid rain, this test provides insights into how metals and coatings will perform in corrosive environments.

Manufacturers also conduct real-world exposure tests by placing furniture in areas with high acid rain frequency. This long-term testing helps validate lab results and assess performance under natural conditions.

By combining these methods, ODM manufacturers ensure outdoor furniture maintains its structural integrity and aesthetic appeal despite acid rain exposure, delivering reliable products to consumers worldwide.
