GB/T 3671.1-1996 "Determination of Solubility and Solution Stability of Water-Soluble Dyes" specifies the test methods for determining the solubility and solution stability of water-soluble dyes, applicable to various types of water-soluble dyes. Solubility is determined by dissolving the dye to saturation at a specified temperature, filtering, and weighing the residue for calculation. Solution stability is assessed by observing the state of the dye solution after standing. The test requires instruments such as a constant-temperature water bath, analytical balance, filtration apparatus, and stoppered measuring cylinder, providing data for controlling the solubility performance of dyes in applications.
