This standard specifies the method for the determination of ash content in carbon black and is applicable to rubber-grade carbon black, acetylene carbon black, and pigment carbon black. The principle involves incinerating the sample at high temperatures (typically several hundred degrees Celsius) to completely combust and volatilize the organic components of the carbon black. The remaining inorganic residue constitutes the ash, and its mass fraction is calculated by weighing. The core testing instruments used in this method are a high-temperature furnace (muffle furnace) and a precise analytical balance. This standard is one of the series of testing standards for carbon black products, and its formulation and revisions have been developed in alignment with the corresponding international standards.
