GB/T 21878-2008 《Water-soluble sulphur dyes - Determination of spectrostrength》 Related products

This standard specifies a method for determining the spectral intensity of water-soluble sulfide dyes and is suitable for evaluating the spectral performance of dyestuff relative to the standard sample. Calculate the percentage of the spectral intensity of the sample relative to the standard sample by formulating the dyestuff solution and measuring the optical density at the wavelength of Maximum absorption on a spectrophotometer. This standard specifies in detail the equipment requirements, test conditions and calculation methods, which help to ensure the color Stability and mass conformity of the product in the production and use of dyestuff.
