Variability in Oil Analysis Results Two consecutive samples, at normal sampling intervals from the same machine, are never expected to have exactly the same results, but occasionally the second set of results appears to have either changed by more than a normal amount, or possibly have shifted in a counter-intuitive direction (i.e. gotten better without…

The Importance of Performing Oil Sampling on a Regular Basis
The importance of oil sampling on a regular basisRoutine oil sampling is the key to a successful maintenance program. Oil testing provides essential information to determine the condition of your equipment. Baseline of normal wear can be established during the first few months of a program. As the program matures, only routinely scheduled testing can…

Understanding Particle Counting Methods
Understanding Particle Counting Methods Particle counting is considered by many to be one of the most important test for used oil analysis. Many problems can be quickly and easily identified by monitoring the number and size-distribution of particles in an oil sample. The ISO Code is the most common unit of reporting the number of…

Know the Proper Base Number of Your Oil
Know the Proper Base Number of Your Oil The base number (BN) is a property that is more associated with engine oils rather than industrial oils. It can be defined as the oil’s ability to neutralize acids that are produced during use. The higher the base number in the engine oil, the more acid it…

How to Design a Successful Oil Analysis Program: Determine Test Packages
How to Design a Successful Oil Analysis Program: Determine Test Packages Oil analysis test packages should be carefully considered. Different equipment have different test profile requirements. When determining what test packages to choose, the actual equipment and the surrounding environment should dictate what tests are appropriate. Keep in mind that with oil analysis your goal…

Testing For Water
Testing For Water Water is one of the most destructive contaminants faced by industrial maintenance departments. Studies have shown that water present at any level can reduce bearing life from 10 to 100 times. While the overall tolerance for water varies from machine to machine, a good general alarm limit for water contamination is 0.05%…
