This standard specifies a method for the determination of large particle content in disperse dyes and reducing dyestuffs using a single-layer filter cloth filtrate method. By making dyestuff into a suspension and then filtrating and comparing it with a standard sample card for rating, the standard provides an important basis for evaluating the fineness and uniformity of dyestuff, ensuring the mass Stability of dyestuff products in practical applications.
