GB/T 46470-2025
Leather—Tests for colour fastness—Colour fastness to migration into polymeric material

GB/T 46470-2025 modifies the adoption of the international standard ISO 15701, specifying test methods for assessing the risk of color migration from leather to polymer materials in contact with it (such as PVC outsoles for footwear and interior artificial leather). By placing leather in close contact with polymers under specific temperature, humidity, and pressure conditions for a certain period, the staining grade on the polymer surface is evaluated.
