This standard specifies the core methods for evaluating the performance of fluorescent whitening agents. It determines the maximum absorption wavelength of the sample and the absorbance value (UV absorption) at this wavelength, comparing them with those of a standard sample to calculate the fluorescence intensity that characterizes its whitening ability. The core instrument for detecting these parameters is an ultraviolet-visible spectrophotometer. This method is applicable to evaluating various types of fluorescent whitening agent products, including both water-soluble and non-water-soluble ones. The results are of significant importance for quality control in industries such as printing and dyeing, as well as detergents.
