COOLANT SPECIFCIATIONS AND TEST METHODS

ASTM D 3634 (Standard Test Method for Trace Chloride Ion in Engine Coolant) Chloride is a common corrosive ion that can potentially be found in coolants, usually from the use of poor quality water. It may also be determined by ASTM 5827 (Standard Test Method for Analysis of Engine Coolant for Chloride and Other Anions by Ion Chromatography).
