If the BS&W test is performed on a 2190TEP Lube Oil sample, what does it primarily measure?

• A. Freezing point
• B. Pour point
• C. Water and sediment contamination
• D. Conductivity

Answer: (C)

Basic Sediment and Water testing is used to determine how much water and solid impurities have contaminated lubricating oil. Water in oil can cause corrosion, emulsions, and reduced lubrication, while sediment and sludge can clog filters and wear surfaces. The test works by separating water and solid contaminants from the oil so their quantity can be measured, giving a direct indication of contamination levels. Freezing point and pour point assess how oil behaves at low temperatures, not impurity content. Conductivity can hint at moisture but isn’t the direct measurement this test provides, which targets both water and sediment specifically.
