BS EN ISO 14720-1:2013

Testing of ceramic raw and basic materials. Determination of sulfur in powders and granules of non-oxidic ceramic raw and basic materials. Infrared measurement methods | Status: Current, Under review

1 Scope This part of ISO 14720 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. This part of ISO 14720 is applicable for materials with mass fractions of sulfur from 0,005 % to 2 %. This part of ISO 14720 can also be applied for materials with higher mass fractions of sulfur after verification of the particular case.
