GB/T 1637-2006 "Soluble Vat Dyes—Determination of Shade and Strength" specifies the methods for determining the shade and strength of soluble vat dyes, applicable to the quality assessment of such dyes. The sample and the standard are dyed or printed on cotton or silk fibers under the same conditions, and the shade is compared by visual inspection or instrumental methods. The strength of the sample is evaluated based on the standard strength set as 100. The detection requires instruments such as a spectrophotometer, analytical balance, steaming box, standard light source cabinet, and printing machine to ensure consistency in the dyeing performance of the dyes.
