Oil Analysis Sampling Practice Recommendations
 Analysis
of used oil is analogous to a laboratory medical analysis with a blood
test. Like blood, lubricating oil contains a good deal of information
about the envelope in which it is circulating. Wear of metallic parts,
for example, produces a lot of minute particles, which are carried by
the lubricant. These small metal particles can give information about
the machine elements that are wearing, and can be detected by various
methods, for example, Atomic Emission Spectrometry. Determination of
larger particles can be done using optical or electronic microscopy, or
ferrography.
InfraRed Imaging
Solutions Inc. (IRIS)
partnered with Wear Check Canada and Wear Check USA for an accurate and
complete analysis of your used oil. Several methods are used to analyze
oil condition and contamination. These include spectrometry, viscosity
analysis, dilution analysis, water detection, Acid Number assessment,
Base Number assessment, particle counting, and microscopy. Oils undergo
destructive changes in property when subjected to oxygen, combustion
gasses and high temperatures. Viscosity change, as well as additive
depletion and oxidation occur to degrade the oil. The causes of oil
contamination are many, and can be classified according to source. Thus
there is contamination coming from outside the system - dust (silica);
liquids (mixture with other oils, water, other contaminated oil). The
second is in open systems - chains, cables, gears in contact with dust,
water, and so on. The third is in closed systems. The critical factor in
oil analysis is the interpretation of the oil analysis results. A
diagnostician interprets the oil test results and produces a concise
summary of the equipment, and oil condition.

Special
Sampling Considerations |
|
Follow up on abnormal samples |
IND 3 |
WearCheck advises that ferrographic analysis be performed with
resamples on equipment that tested abnormal. Filter analysis
allows the diagnostician to locate and detect major wear
situations. |
|
|
|
Extended oil drain intervals |
IND 2 |
Any equipment that is undergoing extended oil drain interval
testing should use MOB 2 test kits. These kits include TAN
testing to monitor the degradation of the oil, as well as the
build up of acids in the oil. Oils with high TAN levels
generally experience oil thickening, sludging, improper oil
flow, and corrosion of components. |
|
|
|
Critical Systems |
IND 3 |
IND 3 kits include the most comprehensive battery of tests to
monitor the oil condition, wear condition, and contamination
levels of the system. |
