Oxidation, nitration and sulfonation of base stocks are monitored as evidence of degradation.

Such limits should be established in conjunction with advice astm e2412 guidance from the machinery manufacturer and maintenance group. This creates a huge issue for some engines, mainly natural gas engines as they operate at higher combustion temperatures and astm e2412 high Nitrous Oxides NOx are formed. This practice is designed for monitoring in-service lubricants and can aid in the determination of general machinery health and is not designed for astm e2412 analysis of lubricant composition, lubricant performance or additive package formulations.

The infrared data generated by this practice is typically used in conjunction with other testing methods. While calibration to generate physical concentration units may be possible, it is unnecessary or impractical in many cases. Warning or alarm limits the point where maintenance action on a machine being monitored is recommended or required can be determined through statistical analysis, history of the same or similar astm e2412, round astn tests or other methods in conjunction with correlation to equipment performance.

Through normal blow-by, when nitrogen oxide products enter the lubricant, the react with the moisture and become acidic in nature and astk accelerate the oxidation rate of the oil. It is not the intent of this practice to establish or recommend normal, astm e2412, warning asym astm e2412 limits for any machinery.

Contaminants monitored include water, soot, ethylene glycol, fuels and incorrect oil. Referenced Documents purchase astm e2412 The documents listed below are referenced within the subject standard but are not provided as part astm e2412 the standard.

Molecular analysis of lubricants and hydraulic fluids by FT-IR spectroscopy produces direct information on molecular species of interest, including additives, fluid breakdown products and astm e2412 contaminants, e22412 thus complements wear metal and other analyses used in a condition monitoring program 13- 2. A number of physical property tests complement wear metal analysis and are used to provide information on lubricant condition for example, Test Methods DDastm e2412 D This includes varnish or lacquer in hot areas of the engine, and sludge in cooler areas of the engine which may lead to ring sticking and filter plugging, respectively Increase in blow-by which will lead to top-end wear.

Increase in viscosity due asstm thickning of the oil Increase in the acidity of the oil resulting in increase in Acid Number AN Increase in insolubles. If the oil is exposed to astm e2412 nitration conditions, the nitration products in the oil will cause: Nitration occours when there is sufficient heat and pressure in the asstm chambers of the engines which breakes the atmospheric nitrogen molecule down to astm e2412 atoms which thereafter react with oxygen to form Nitrous Oxides NOx.

If the oil is exposed to severe nitration conditions, the nitration astm e2412 in the oil will d2412.

ASTM E – standard practice for Condition Monitoring of Used Lubricants by FT-IR Spectrometry.

Testing Equipment used by us in e412 laboratory: Measurement and data interpretation parameters are presented to allow operators of different FT-IR aetm to compare results by employing the astm e2412 techniques.

The objective of this monitoring activity is to diagnose the operational condition of the machine based on fault astm e2412 observed in the oil.

These warning or alarm limits can be astm e2412 fixed maximum or minimum asym for comparison to a single measurement or can also be based on a rate of change of the response measured 1. The testing of Nitration is done in our laboratory by using FTIR Fourier transform infrared spectrometer, which can be coupled with Acid Number Test and Viscosity to determine the extent of nitration and degradation of the astm e2412.

The practice as presented is not intended for the prediction of lubricant physical properties for example, viscosity, total base number, total acid number, etc.

It is the responsibility of astm e2412 user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of astk limitations prior to use.
