How do manufacturers test the slip resistance of resin-treated WPC Outdoor Loungers?

Manufacturers test the slip resistance of resin-treated WPC (Wood-Plastic Composite) Outdoor Loungers using standardized methods to ensure safety and performance. Common techniques include the ASTM F1679 (Mark II) test, which measures the coefficient of friction on wet and dry surfaces. The process involves placing the lounger material on an inclined plane and gradually increasing the angle until slippage occurs. Additionally, some manufacturers use the DIN 51130 standard, which evaluates slip resistance under realistic conditions, such as with contaminants like oil or water. These tests help verify that the resin treatment enhances grip, making the loungers suitable for outdoor use in wet or slippery environments. Advanced labs may also employ tribometers for precise friction measurements. By rigorously testing slip resistance, manufacturers ensure compliance with safety standards and customer expectations.
