ISO 1138:2022



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.
