    Alcohol soluble dyes - Determination for general properties of application

    GB/T 12680-2008 "Alcohol-soluble Dyes - Determination of General Properties" specifies the methods for determining the general properties of alcohol-soluble dyes, such as solubility, strength, hue, and fineness. It is applicable to various types of alcohol-soluble dye products. Solubility is determined using spectrophotometry or gravimetry, strength and hue are evaluated by comparison with standard samples, and fineness is tested by sieving. Instruments such as spectrophotometers, analytical balances, standard sieves, and constant-temperature water baths are required. This standard provides a unified technical basis for the quality control of alcohol-soluble dye products.
