Lubricating Oil Sampling Procedures
Lubricating Oil Sampling ProceduresTo properly evaluate machine conditions, the oil samples submitted for analysis must be representative of the system from which they are taken. For best results, follow these guidelines:1. The machine being sampled should be brought to normal operating temperature. ...

Infrared Analysis - Lubricating Oil Analysis
Infrared Analysis - Lubricating Oil AnalysisInfrared Spectroscopy ("IR" or "FTIR") is a technique that is very useful for: identifying oil and foreign-body contamination, identifying additive concentrations or depletions, and identifying oil degradation reactions. The technique is based on the principle ...

Wear Metals/Elemental Analysis - Lubricating Oil Analysis
Wear Metals/Elemental Analysis - Lubricating Oil AnalysisElemental analysis is used to evaluate and quantify wear metal elements, additive elements and contamination elements. Wear metals are analyzed to pinpoint problem areas through trend analysis. By analyzing the additive elements, the oil type can ...

Particle Count - Lubricating Oil Analysis
Particle Count - Lubricating Oil AnalysisFluid cleanliness is critical in hydraulic and other systems where high fluid pressure and velocity are involved. Excessive fluid particulate contamination is a major cause of failure of hydraulic pumps, motors, valves, pressure regulators, and fluid controls. ...

Total Base Number (TBN) - Lubricating Oil Analysis
Total Base Number (TBN) - Lubricating Oil AnalysisThe total base number is an expression of the amount of alkaline additives in the lubricant that are capable of neutralizing the acid products of combustion.A new oil starts with the highest TBN it will possess. During the time the lubricant is in service, ...
-
Total Acid Number (TAN) - Lubricating Oil Analysis
Total Acid Number (TAN) - Lubricating Oil AnalysisThe total acid number is the quantity of acid or acid-like constituents in the lubricant. An increase in TAN from that of the new lubricant should be monitored. The TAN of a new oil is not necessarily zero since oil additives can be acidic in nature. ...

Nitration - Lubricating Oil Analysis
Nitration - Lubricating Oil AnalysisNitration products are formed during the fuel combustion process when combustion by-products enter the engine oil during normal operation or as a result of abnormal "blow-by" past the compression rings. These products, which are more common in oils used to lubricate ...

Oxidation - Lubricating Oil Analysis
Oxidation - Lubricating Oil AnalysisLubricating oil in engines and other components combines with available oxygen under certain conditions to form harmful by-products. Heat, pressure, and catalyst materials accelerate the oxidation process. By-products of oxidation form lacquer deposits, corrode metal ...

Fuel Soot - Lubricating Oil Analysis
Fuel Soot - Lubricating Oil AnalysisFuel soot is composed of carbon and is always found in diesel engine oil. Laboratory testing is used to determine the quantity of fuel soot in used oil samples. Stringent exhaust emission regulations have placed greater emphasis on fuel soot levels. One of the most ...
