How to take a good lubricating oil sample?

How can we obtain a good lubricating oil sample? Oil samples in tiny bottles ranging in size from 50 mL to 150 mL are collected for routinely used oil analysis. Because the samples are from a large system, it is critical that the captured oil be fully representative in order for the analysis to statistically represent current conditions in terms of degradation, contamination, and wear. As a result, sampling techniques are critical.

Quality of Oil

Sampling should be done while the machinery is running (provided it is safe to do so) or within 30 minutes after shutdown. The sampling procedure described below should be adopted as best practice and used consistently for all subsequent samples so that findings may be compared with reliability.

Purging of Sampling Point

Before collecting oil, flush the sample connection to eliminate any dirt or impurities. It is advised that enough oil be drained to ensure that the sample is clean and representative.

Good Lubricating Oil Sampling Volume

Make sure the sample bottle is at least 80% filled. This is done to guarantee that there is enough material to complete the whole test package and to allow the laboratory to homogenize the sample.
