GB/T 3671.2-1996 "Determination of Cold Water Solubility of Water-Soluble Dyes" specifies the method for determining the solubility of water-soluble dyes in cold water, applicable to various types of water-soluble dyes. In cold water at 25°C ± 1°C, the dye is gradually added and stirred until saturation is reached. After filtration, the undissolved portion is weighed to calculate solubility. The test requires instruments such as a constant temperature water bath, analytical balance, magnetic stirrer, and filtration apparatus, specifically evaluating the dye's solubility in low-temperature aqueous environments.
