1 Scope
This International Standard specifies three methods for the determination of the total
sulfur in all types of carbon black for use in the rubber industry:
-
— Method A, using an oxygen bomb calorimeter;
-
— Method B, using a combustion furnace;
-
— Method C, using an automatic analyser.
With respect to safety aspects and test precision, it is preferable to use automatic
systems. Classical chemical analysis (Method A and Method B) is acceptable if automatic
equipment is not available.
