What must be eliminated during the oil sampling process?

The focus during the oil sampling process is to obtain an uncontaminated sample that accurately reflects the condition of the lubricant within an equipment system. Hence, all forms of contamination must be eliminated. This includes any substances or particles that could interfere with the analysis, such as dirt, water, other fluids, or gaskets that may deteriorate. Contamination can lead to inaccurate readings and misinterpretation of the oil's condition, resulting in poor decision-making regarding maintenance or replacements.

While factors like heat exposure, air pressure variations, and material obstructions may impact the sampling process, the primary concern is ensuring that the sample itself is free from contamination to provide reliable diagnostic information related to the equipment's health. Thus, emphasizing the elimination of all forms of contamination is crucial for the integrity of the oil analysis.
