ISO 14596:2007规定了一种用于测定液体石油产品，石油产品添加剂和半固体和固体石油产品的硫含量的方法，其通过适度加热液化或溶于可忽略或准确已知硫的有机溶剂中内容。该方法适用于含量在0.001％（m/m）至2,50％（m/m）范围内的硫含量的产品或添加剂;较高的含量可以通过适当的稀释来确定。其他要素不会影响受到本分析的材料预期的浓度

ISO 14596:2007 specifies a method for the determination of the sulfur content of liquid petroleum products, additives for petroleum products, and semi-solid and solid petroleum products that are either liquefied by moderate heating or soluble in organic solvents of negligible or accurately known sulfur content. The method is applicable to products or additives having sulfur contents in the range 0,001 % (m/m) to 2,50 % (m/m); higher contents can be determined by appropriate dilution. Other elements do not interfere at concentrations anticipated in the materials subject to this analysis.
