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