Standard Test Method for Trace Ethylene Glycol in Used Engine Oil

SIGNIFICANCE AND USE
Leakage of aqueous engine coolant into the crank case weakens the ability of the oil to lubricate. If ethylene glycol is present, it promotes varnish and deposit formation. This test method is designed for early detection to prevent coolant from accumulating and seriously damaging the engine.
SCOPE
1.1 This test method covers the determination of ethylene glycol as a contaminant in used engine oil. This test method is designed to quantitate ethylene glycol in the range from 5 to 200 mass ppm.
1.2 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 specific warning statements, see Section 6.
Note 1—A qualitative determination of glycol-base antifreeze is provided in Test Methods D 2982. Procedure A is sensitive to about 100 ppm.
