The HG/T 3689-2014 standard specifies testing methods for yellowing resistance of footwear materials such as liners and substrates. Methods A (solar lamp method) and B (ultraviolet tube method) are used to simulate the effect of sunlight or ultraviolet rays on footwear materials and to evaluate the degree of color change. The standard applies to white and light-colored footwear materials to ensure their yellowing performance under light, helping manufacturers improve the durability and aesthetics of footwear materials.
