ISO 14720-1:2013定义了一种测定粉末和粒状非氧化陶瓷原材料和材料（如碳化硅、氮化硅、石墨、炭黑、焦炭、碳粉）中硫的方法。如果回收率证明，该方法也适用于其他非金属粉末和粒状材料，例如二氧化硅。 ISO 14720-1:2013适用于硫质量分数为0005%至2%的材料。 ISO 14720-1:2013也适用于特殊情况验证后硫质量分数较高的材料。

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.
