Active Standard: Standard Test Method for Chloride Ions in Brackish Water, Seawater, and Brines

ASTM D4458

Scope

1.1 This test method2 is applicable to the measurement of chloride in highly mineralized waters such as oil field brines, seawater, and brackish water. The test method is based upon the titration of chloride with silver nitrate, using a visual indicator.
