Scope

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.
