3 Categories of Lubrication Analysis

3 Categories of Lubrication Analysis

What are the 3 categories of lubrication analysis?

  1. Machine Health
  2. Lubricant Health
  3. Contamination

1. Machine Health

For machine health lubricant analysis, we are looking for the presence of wear metals that may have generated from components in the oil. After sampling, we can see if it's normal or severe wear.

Test Methods:

  • Analytical Ferrography
  • Ferrous Wear Concentration
  • Elemental Spectroscopy

2. Lubricant Health

we are looking to see if the lubricant is still fit for use. And one of the best ways to accomplish this is to ensure that you are using the correct lubricant. You would be surprised how many cases we see where the wrong lubricant is being used.

We also want to make sure that there hasn't been a significant degradation in the lubricant.

Test Methods:

  • FTIR Spectroscopy
  • Acid Number
  • Viscosity
  • Elemental Spectroscopy

3. Contamination

We are looking for any form of material that may have entered the lubricating system.

Test Methods:

  • Particle Count
  • Water Content
  • Elemental Spectroscopy

Oil Analysis Testing Methods

For each of these 3 categories of lubrication analysis, we use over 50 methods to ensure accurate results. In this blog, we have listed the main 8 testing methods we use and which category they are most often used in.

8 Main Oil Analysis Testing Methods

  1. Analytical Ferrography
  2. Ferrous Wear Concentration
  3. FTIR Spectroscopy
  4. Acid Number
  5. Viscosity
  6. Particle Count
  7. Water Content
  8. Elemental Spectroscopy

All of these testing methods can be used for each category, but some are naturally going to provide more accurate results. Elemental spectroscopy is a great test method that can fit in all three categories because with this test, we are looking for the presence of wear metals, the presence of elements used as lubricant additives, and the presence of elements that could be associated with contamination.
