Standard Test Method for Trace Quantities of Water in Aromatic Hydrocarbons and Their Mixtures by Coulometric Karl Fischer Titration
 N D7375

Annotation

This test method describes the use of the Coulometric Karl Fischer (KF) titration for the determination of water in aromatic hydrocarbons and their mixtures, derivatives and related chemicals.

This test method is applicable to samples with water concentrations from 10 to 400 mg/kg.

In determining the conformance of the test results using this method to applicable specifications, results shall be rounded off in accordance with the rounding-off method of Practice E 29.

Values stated in SI units are to be regarded as the standard. The preferred units are milligrams per kilogram (mg/kg).

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For a specific hazard statement see Section 8.
