ISO 14596:2007规定了测定液体石油产品、石油产品添加剂以及半固体和固体石油产品的硫含量的方法，这些石油产品通过适度加热液化或可溶于含硫量可忽略或准确已知的有机溶剂中。该方法适用于硫含量在0.001%(m/m)至2.50%(m/m)范围内的产品或添加剂；更高的含量可以通过适当稀释来测定。在进行该分析的材料中的预期浓度下，其他元素不会干扰。

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.
