GB/T 33421-2016 《Liquid acid dyes—Determination of shade and relative strength》 Related products
The GB/T 33421-2016 standard specifies methods for the determination of the color light and intensity of liquid acidic dyestuff. The standard includes dyeing method, which evaluates the color light and intensity by comparing with the standard sample, and solution Colorimetry, which calculates the intensity of dyestuff by measuring Absorbance by spectrophotometer. The color light and intensity evaluation suitable for liquid acidic dyestuff helps to ensure the performance conformity of dyestuff in practical applications.
