GB/T 21892-2015 "p-Aminophenol" specifies the requirements, sampling, test methods, inspection rules, as well as marking, labeling, packaging, transportation, and storage of p-aminophenol products, and is applicable for the quality control of such products. Compared to the previous version, the standard adjusts indicators such as purity and amino value, and introduces new control items including transmittance, nickel content, and sodium metabisulfite. Testing requires instruments such as high-performance liquid chromatography, ultraviolet-visible spectrophotometers, and atomic absorption spectrophotometers. The standard also references relevant standards to regulate the testing process, providing a unified technical basis for quality verification of p-aminophenol products.
