This standard defines a method for the determination of sulphur in powdered and granular non-oxidic ceramic raw materials and materials, which are completely oxidised at higher temperature in an oxygen atmosphere, e.g. carbon and graphite materials. For materials, which are not completely oxidisable under these conditions, it is possible to determine sulphur,that can be released under these conditions e.g. the adherent sulphur. This standard is applicable for materials with mass contents of sulphur < 10 % and ash contents < 20 %. The defined method is limited for materials with mass contents of barium < 10 mg/kg, because the sulphur bonded in barium sulfate is not detectable with this method. For the lower detection limit of this method a sulphur content of 0.5 mg/kg in case of ICP OES and 5 mg/kg in the case of IC, has to be considered as recommended value.
