ActiveFlexible cellular polymeric materials—Determination of fatigue by a constant-strain procedure
柔性多孔聚合物材料 恒定形变法测定疲劳性能
Application Summary AI generated
This standard specifies a test method for determining the fatigue resistance of flexible cellular polymeric materials, such as polyurethane foams, under repeated constant-strain compression. It is applied in the quality control and material selection processes for products like mattresses, upholstered furniture, and automotive seating, where long-term durability under cyclic loading is critical. The procedure simulates real-world usage conditions to evaluate how the material's mechanical properties degrade over time.
