GB/T 14853.4 - 2013 is a standard for the determination of the accumulation strength of carbon black granulated for rubber. It clearly stipulates the specific operation process from sample collection, instrument preparation to determination of the accumulation strength, covering test conditions setting, data recording and result calculation methods. The accumulation strength is a key indicator for measuring the mass and performance of granulated carbon black, which affects its storage, transportation and application in rubber processing. The standard provides unified testing specifications for carbon black production and Rubber enterprises, helps to control product mass, optimize production links, and promote the standardization process of testing in the rubber granulated black carbon industry.
