Bibliography

This standard specifies a potentiometric method for the determination of inorganic chloride content in ethanol from 4 mg/l to 30 mg/l. The chloride content is determined in aqueous solution after dissolution of the evaporation residue of the ethanol sample.WARNING — Use of this standard may involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.NOTEFor the purposes of this document, the terms “% (m/m)” and “% (V/V)” are used to represent respectively the mass fraction and the volume fraction.
