    Dyes - Determination of pH value

    GB/T 2390-2013 "Determination of pH Value of Dyes" specifies the method for determining the pH value of dyes, which is applicable to the testing of relevant indicators for various types of dyes. The test involves accurately weighing the sample using an analytical balance, preparing a dye aqueous solution or dispersion of specified concentration with a volumetric flask and pipette, and measuring the pH value of the solution at a specified temperature using a precision pH meter. The testing process requires ensuring that the instruments are properly calibrated, providing fundamental data for adjusting the pH value of the dye bath and controlling dyeing effects during dye application.
