This standard describes a method for determining the solvent resistance of pigments to evaluate the Stability of pigments in solvents. The solvent resistance of pigments means that they are not easily dissolved in solvents, thereby reducing the staining of solvents. The standard specifies the required chemically pure solvents, testtubes, Electric Oscillators and other materials and instruments, and provides detailed steps for testing. This method provides a standardized basis for evaluating the performance of pigments in different solvent environments, ensuring their performance and Reliability in practical applications.
