Episode 046 | Oil Analysis Limits with Elaine Hepley (Polaris Laboratories)
Ғылым және технология
Oil analysis - your business is most likely doing it, collecting the data, and then never looking at the data ever again. How do I know this? Because I have seen countless examples.
In this podcast, Elaine Hepley from Polaris Laboratories takes a look at oil analysis data, how it is analysed, and how we set limits.

Great content. Agree that only the surface was adressed. The guest was very knowledgable.
Great episode! Thank you!!

Thanks for watching Gary! Elaine is a superstar.
The company I work for has a single reporting application for condition monitoring (and more). Good thing is it automatically pulls our sample data from the labs database for us to analyze. We've just recently started with some auto acknowledgement of samples so it saves us having to look at many samples that are flagged as heathy from the lab (because the labs don't really have time for proper analysis I always check the healthy UOA results along with moderate, abnormal, severe etc..). Its not a perfect system as there are absolute limits in place for various elements/cleanliness etc. that may not always be practical or workable for every piece of equipment, but from my side as a technician there is some time saving advantages where we are only looking at samples that have some potential issue that is progressing.
Absolute values make sense when time is irrelevant. For example, lead in engine oil, it does not matter if 100 hours or 500 hours. If lead is above for example 3 ppm this is usually a key indicator ( aswell as others) that the oil is deteriorating. However lead can also be a wear indicator aswell (when present in certain alloys) in which case time may or may not be relevant aswell.

Good point
Where can I find a list of top lubricant formulation labs and what are common tests slates for lubricants as formulations are modified?

Common test slates for lubricant properties are elemental analysis, Acid Number or Base Number, viscosity either at 100 or 40 degrees and then there is oxidation, nitration. In some cases FTIR spectra can be helpful as well. There are other specialized tests such as Water Separability, air release, foam that can also be done but not all of these tests are applicable for all fluid types. It really just depends on what you are looking for to manage with your fluid analysis program. What are some of your issues you see or have? Start with that.
