BS ISO 1138:2007+A1:2012

Rubber compounding ingredients. Carbon black. Determination of sulfur content. | Status: Superseded, Withdrawn

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.
