How do ODM manufacturers test for water resistance in outdoor furniture?

ODM manufacturers employ rigorous testing methods to ensure outdoor furniture meets water resistance standards. Common techniques include spray testing, submersion tests, and humidity chambers. Spray testing simulates rain exposure, while submersion evaluates prolonged water contact. Humidity chambers assess material durability in damp conditions. Manufacturers also use industry standards like ISO 2448 or ASTM D870 for consistency. High-quality materials like powder-coated aluminum or UV-resistant fabrics are often tested to guarantee long-term performance. These methods help ODM producers deliver durable, weather-resistant outdoor furniture to global markets.
