適用范圍：Is applicable to NR, CR, SBR, BR, IR, IIR, EPDM, NBR, and ebonite (see ISO 1629). The principle of the method is oxidation by ignition in an atmosphere of oxygen in the presence of hydrogen peroxide, conversion of sulfur to sulfuric acid, and determination of the sulfate by titration with barium perchlorate. The method is applicable for the determination of all the sulfur present in a rubber or rubber product, except that contained in barium sulfate.
