ASTM D5827

Analysis of Engine Coolant for Chloride and Other Anions by Ion Chromatography

Applicability: ASTM D5827 is a standard test method used for the chemical analysis of engine coolant for chloride and several other common anions. It is applicable to both new and used engine coolant, and samples can be analyzed directly without pretreatment other than dilution as required by the linear range of the equipment.

Purpose: The purpose of ASTM D5827 is to qualitatively and quantitatively determine chloride and other common anions in engine coolant by high-performance ion chromatography (HPIC), covering the milligrams per litre to low percent range in a single chromatographic analysis. Results are used to evaluate coolant against manufacturers’ blending specifications and applicable ASTM specification limits.
