Methods of test for petroleum and its products. Determination of chlorine and bromine content. Wavelength-dispersive X-ray fluorescence spectrometry Ingestion-build-78747 Specifications are also given for1 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 0,000 5 % (m m) to 0,100 0 % (m m), and
