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.
