    Dyestuffs - Determination of particle fineness - Microscope method

    GB/T 27596-2011 "Dyes — Determination of particle fineness — Microscopic method" specifies a method for determining the particle fineness of dyes using a microscope, applicable to the testing of disperse dyes and vat dyes. The principle involves observing the number of large particles with a particle size greater than 2 μm within a specific field of view under a microscope to qualitatively assess the fineness. The testing requires instruments such as a biological microscope with a magnification of at least 600× (equipped with an eyepiece micrometer), an electronic balance, and an electromagnetic stirrer, providing a standardized method for quality control of dye particle morphology.
