ActiveFlexible cellular polymeric materials—Determination of compression set under humid conditions
柔性多孔聚合物材料 在潮湿条件下压缩永久变形的测定
Application Summary AI generated
This standard specifies a test method for measuring the compression set of flexible cellular polymeric materials, such as polyurethane foams, after exposure to humid conditions. It is applied in quality control and product development for materials used in sealing, cushioning, and insulation applications where moisture resistance is critical, including automotive interiors, furniture, and construction. The test evaluates how well these materials retain their elastic properties under combined compressive stress and high humidity, ensuring long-term performance in damp environments.
