Résumé
ISO 14720-1:2013 defines a method for the determination of sulfur in powdered and granular non-oxidic ceramic raw materials and materials, such as silicon carbides, silicon nitrides, graphites, carbon blacks, cokes, carbon powders. If proved by the recovery rate, this method can also be applied for other non-metallic powdered and granular materials, e.g. silicon dioxide.
ISO 14720-1:2013 is applicable for materials with mass fractions of sulfur from 0,005 % to 2 %.
ISO 14720-1:2013 can also be applied for materials with higher mass fractions of sulfur after verification of the particular case.
