EUROLAB laboratory provides testing and compliance services within the scope of ASTM D2982 standard. These test methods cover the qualitative determination of glycol-based antifreeze in used lubricating oils (mineral base) with two procedures, one using reagents in tablet form and the other using laboratory shelf reagents.
In principle, test methods detect ethylene glycol, but also detect other 1,2-glycols that may be present.
When a positive result is obtained and a sample of unused oil is available, the unused oil is also tested and used as a reference.
Since the inception of this test method (1971), there have been many changes in base stock technology and additive technology. Therefore, when available, new, unused oil or a known sample of the same used oil free of antifreeze is tested as a reference.
If the glycol has deteriorated or oxidized thermally or otherwise, glycol-based coolant leaks into the crankcases may go undetected or result in low drift using these test methods.
Conditions in the crankcases may be such that the polluting glycols are sufficiently biased that the color indicator reaction does not occur or trigger a color change, to oxidize or degrade to such a degree.
Other test methods for the detection of coolants or coolant additives in lubricating oils should be used if results from these test methods alone are unsatisfactory or questionable.
Carbohydrates, such as sugars and sugar-containing substances, are sometimes used for sabotage purposes. If the presence of these substances is suspected, Procedure A includes a modification to eliminate these interactions.
Values stated in SI units should be accepted as standard. No other units of measurement are included in this standard.
This standard does not purport to address all, if any, safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health and environmental practices and to determine the applicability of regulatory restrictions prior to use.
