GB/T 13892-2020 specifies the method for determining the iodine value of surfactants. The standard details the determination principle and covers the applicable surfactant types. There are clear specifications from the collection and preparation of samples, to the selection of reagents and operation steps during the determination process. Through a unified determination process, the iodine value of surfactants can be accurately obtained, providing a key basis for judging their unsaturation and mass. It is widely used in daily chemicals, chemical industries and other industries involved in surfactant production and testing.
