The GMW 3417-2011 standard specifies the natural climate exposure test method for automotive interior decoration and materials. This test aims to simulate the long-term exposure of materials under actual natural climate conditions to evaluate their durability and performance changes. The standard covers the exposure conditions of samples, test procedures and requirements for performance evaluation to ensure the Reliability and suitability of materials in various environments. The standard provides an important reference for the weathering resistance of interior materials to ensure their stable performance in actual use.
