ISO 1138:2007


ISO 1138:2007 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.
