This International Standard specifies a method for the determination of the fraction of a test portion of pelletized carbon black that will pass through a sieve with 125 μm nominal aperture size under specified conditions (i.e. the fines content). It is applicable to all types of pelletized carbon black for use in the rubber industry.
