GB/T 3780.30 - 2023 is part 30 of the carbon black standard, focusing on the determination of high temperature volatiles, using thermogravimetric method. The standard stipulates the use of equipment such as Thermal Gravimetric Analyzer to clarify sample preparation requirements, such as sample volume and storage method. Detailed description of operating parameters such as heating procedure and Temperature range, and accurate determination of high temperature volatiles by recording the mass change of the sample during the heating process. This provides a key means for carbon black quality control, helping manufacturers to control product purity and Stability, and meet the strict requirements of carbon black quality in rubber, plastics and other industries.
