This document specifies two methods for the determination of the total sulfur in all types of carbon black for use in the rubber industry:
— Method A, using a combustion furnace;
— Method B, using an automatic analyser.
With respect to safety aspects and test precision, it is preferable to use automatic systems. Method B is therefore the preferred method. Classical chemical analysis (Method A) is acceptable if automatic equipment is not available.
