This standard is a quality testing method standard for carbon black and powder agents used in rubber products. Its core specifies the procedure for determining sieve residue using the water washing method. This method involves washing the sample on a standard test sieve with water as the medium to separate and measure the mass fraction of coarse particles (sieve residue). The standard explicitly applies to materials such as carbon black that have not been oil-treated and is not suitable for oil-treated materials. This test is crucial for evaluating the dispersibility, purity, and processing performance of carbon black in rubber products, serving as a key basis for quality control in related industries.
