GB/T 3780.14 - 2010 is a standard for the determination of sulfur content in carbon black. It clearly specifies the measurement process of sulfur content in carbon black, from sample collection, pretreatment to selection of appropriate detection methods, such as combustion method, as well as result calculation and data processing. Sulfur content affects carbon black performance and application, especially in rubber and other industries. The standard provides a unified measurement method for carbon black production, trade and use enterprises, which helps to control product mass, ensure that carbon black meets the mass requirements of relevant industries, promote the standardization of carbon black industry testing, and improve product Stability and applicability.
