GB/T 13892-2012 is a standard for determining the iodine value of surfactants. The standard specifies the collection and preparation process of samples in detail to ensure that the samples can accurately reflect the characteristics of surfactants. The reagents and instruments used to determine the iodine value are clarified, and the accuracy of instruments such as Burette is strictly required. In terms of test operation, the reaction conditions, titration steps and data processing methods are clearly stated. By following this standard, the iodine value of surfactants can be accurately determined, which can be used to evaluate the degree of unsaturation of surfactants, providing key data support for the production, application and quality control of surfactants in chemical, daily chemical and other industries.
