本国际标准规定了测定液体中氯和溴含量的方法 石油产品、合成油和流体以及石油产品添加剂（包括废油） 可溶于氯/溴含量可忽略或准确已知的有机溶剂。该方法适用于 含氯量在0,000 5%(m/m)至0,1000%(m/m)范围内的产品或添加剂，以及溴 含量范围为0.001%(m/m)至0.1000%(m/m)。其他元件通常不会干扰，尽管铅 含量高于0,150%（m/m）时可能会产生干扰（参见注释2）。 注1就本国际标准而言，术语“%(m/m)”用于表示 材料。 注2:由于潜在干扰元素的范围相对较高，使用过的润滑剂可能会带来特殊问题 集中。对于一般使用过的润滑剂，灵敏度的下限可以是0,005 0%(m/m)，即使当 9.3的最后一段适用。

This International Standard specifies a method for the determination of the chlorine and bromine content of liquid petroleum products, synthetic oils and fluids, and additives for petroleum products (including used oils) that are soluble in organic solvents of negligible or accurately known chlorine/bromine content. The method is applicable to products or additives having chlorine contents in the range 0,0005 % (m/m) to 0,1000% (m/m), and bromine contents in the range 0,0010 % (m/m) to 0,1000% (m/m). Other elements do not generally interfere, although lead may interfere at contents above 0,1500 % (m/m) (see note 2). NOTE 1 For the purposes of this International Standard, the term "% (m/m)" is used to represent the mass fraction of a material. NOTE 2 Used lubricants may pose particular problems due to the range of potentially interfering elements at relatively high concentrations. For used lubricants generally, the lower limit of sensitivity may be 0,0050 % (m/m) even when the provisions of the last paragraph of 9.3 are applied.
