GB/T 12688.4-2011 《Test method of styrene for industrial use - Part 4：Determination of content of peroxides - Titrimetric method》 Related products

GB/T 1 2688.4 - 2011 Part 4 provides for the determination of peroxide content in industrial styrene by Titrimetric method. It is suitable for all kinds of industrial styrene products. The styrene sample is reacted with a specific reagent, and the peroxide is involved in the reaction. The peroxide content is calculated by the amount of titrant. The standard specifies the requirements of Burette and other instruments, and specifies the preparation and calibration of reagents. Detailed description of Sample Handling steps, including sample collection, storage and pre-experiment preparation. Standardized titration operation procedures, such as titration speed control and end point judgment. According to this standard, the peroxide content can be accurately determined, which helps industrial styrene mass control and production safety assurance.
