GB/T 7383-2007 is for the determination of hydroxyl value of nonionic surfactants. It clarifies the determination principle, stipulates the reagents, instruments, etc., and elaborates the operation process in detail, including Sample Handling, reaction conditions, titration steps, etc., which can accurately determine the hydroxyl value. This standard provides a key means for mass control of nonionic surfactants, helps manufacturers monitor product performance, standardizes industry detection methods, ensures stable mass of different batches of products, and promotes standardization and standardization of the nonionic surfactant industry.
