Standard Test Method for Determination of Acids and Glycol Esters in Ethylene Glycol
N D7736
Annotation
This test method covers the determination of free acids and glycol esters in ethylene glycol by titration.
This test method is for used on ethylene glycol used for the manufacture of engine coolant. It can not be used on formulated engine coolant. The inhibitors will interfere with the determination.
The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
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.
