Testing of ceramic raw and basic materials - Determination of content of sulphur in powders and granules of non-oxidic ceramic raw and basic materials - Part 2: Optical emission spectrometry by inductively coupled plasma (ICP OES) or ion chromatography (I
This draft standard specifies a method for the determination of content of sulphur in powders and granules of ceramic raw and basic materials by optical emission spectrometry by inductively coupled plasma (ICP OES) or ion chromatography (IC) after burning in an oxygen flow. It is applicable to materials with mass fractions of sulphur less than or equal to 10 %, of ignition residue less than 20 % and of barium less than 10 mg/kg. Mass fractions of sulphur of 0,5 mg/kg when determined by ICP OES and of 5 mg/kg when determined by IC are guide values for the low application range of this method.
