GB/T 41793-2022 "Test Methods for Artificial Leather and Synthetic Leather - Determination of Potential Phenolic Yellowing" is a testing method used to evaluate the degree of phenolic-induced yellowing that artificial leather and synthetic leather may undergo under specific conditions. This method simulates the material's exposure to phenolic substances (such as certain papers, woods, and adhesives) during packaging, storage, or use, in the presence of oxidizing agents like nitrogen oxides, to assess its tendency for color change. Related detection instruments typically include aging test chambers used to create and control constant temperature and humidity conditions, as well as yellowing resistance test chambers for accurately simulating and accelerating the test environment.
