As components wear, elements are suspended in the lubricant. S•O•S Fluid Analysis can measure the levels of these wear elements and provide insight into the condition of the component.
Trend analysis (the comparison of historical oil sample results as the basis for normal test results) and proprietary wear tables are used to determine if wear rates are normal or abnormal.
Trends are established by repeated oil sample results from the same compartment. Three to five samples are needed to establish a trend, making regular sampling a critical part of your maintenance program.
