ASTM D5808 is the Standard Test Method for Determining Organic Chlorine in Aromatic Hydrocarbons and Related Chemicals by Microcoulometry
This test method covers the determination of organic chloride in aromatic hydrocarbons, their derivatives, and related chemicals.
The method is applicable to samples with chloride concentrations to 25 mg/kg. The limit of detection (LOD) is 0.2 mg/kg and the limit of quantitation (LOQ) is 0.7 mg/kg. With careful analytical technique or the measurement of replicates, or both, this method can be used to successfully analyze concentrations below the LOD.
