GB/T 10661-2010 "Fluorescent Brightener VBL (C.I. Fluorescent Brightener 85)" specifies the requirements, test methods, inspection rules, and other relevant content for this product, applicable for its quality control. The standard covers indicators such as appearance, fluorescence intensity, whitening intensity, and shade, with newly added limit requirements for heavy metal elements and harmful aromatic amines. The determination of fluorescence intensity requires the use of instruments such as a UV-visible spectrophotometer and a 10mm quartz cuvette, measuring the extinction value at a wavelength of 348nm to calculate the results, providing a technical basis for product quality consistency and safety.
