It is not the intent of this practice to establish or recommend normal, cautionary, warning astm e2412 alert limits for any machinery.

Contaminants monitored include water, soot, ethylene glycol, fuels and incorrect oil. The objective of this monitoring activity is to diagnose the operational condition of the machine based on fault conditions observed astm e2412 the oil.
Such limits should be established in conjunction with advice and guidance from the machinery manufacturer and maintenance group. This creates a huge issue for some engines, mainly astm e2412 gas engines as they operate at higher combustion temperatures and therefore high Nitrous Oxides NOx are formed. The testing of Nitration is done in our laboratory by using FTIR Fourier transform infrared spectrometer, which can be coupled with Acid Astm e2412 Test and Viscosity to determine the extent of nitration and degradation of the oil.
The infrared data generated by this practice is typically astm e2412 in conjunction with other testing methods.
This includes varnish or lacquer in hot areas astm e2412 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. Level Zero and Level One Tests.
Work Item s – proposed revisions of this astm e2412.
ASTM E – standard practice for Condition Monitoring of Used Lubricants by FT-IR Spectrometry.
It is the responsibility of the user of this standard to establish astm e2412 safety, health, and environmental practices and atm the applicability of regulatory limitations prior to astm e2412. Link to Active This link will always route to the current Active version of the standard. Increase in viscosity due to thickning of the oil Increase in the acidity of the oil resulting in increase in Acid Number AN Increase in insolubles.
These warning or alarm limits can be a fixed maximum or minimum value for comparison to a single measurement or can also be based on a rate astj change of the response measured 1.
Warning or alarm limits the aetm where maintenance action on a machine being monitored is recommended or required can be determined through statistical analysis, history of the same or similar equipment, round robin tests or other methods in astm e2412 with correlation to equipment performance. Nitration Testing Equipment used by us in our Laboratory.
Testing Equipment astm e2412 by us in our laboratory: Nitration occours when there is sufficient heat and pressure in the combustion chambers of the engines which breakes the atmospheric nitrogen molecule astm e2412 to two atoms which thereafter react with oxygen to form Nitrous Oxides NOx.
The practice astm e2412 presented is not intended for the prediction of lubricant physical properties for example, viscosity, total base number, total acid number, etc. Measurement and data interpretation parameters are presented to astm e2412 operators of different FT-IR spectrometers to compare results by employing the same techniques.
Through normal blow-by, when nitrogen oxide products enter the lubricant, the react with the moisture and become acidic in nature and rapidly accelerate the oxidation rate of the oil.
A number of physical property tests complement wear metal analysis and are used to provide information on lubricant condition for example, Test Methods DDand D This practice is designed for monitoring in-service lubricants and can aid in the determination of general machinery health astm e2412 is not designed for astm e2412 analysis of lubricant composition, lubricant performance or astm e2412 package formulations.
Oxidation, nitration and sulfonation of base stocks are monitored as evidence of degradation.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are astn provided as part of 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 external astm e2412, and thus astm e2412 wear metal and other analyses used in a condition monitoring program 13- 2. While calibration to generate physical concentration units may be possible, it is unnecessary or impractical in many cases.
Historical Version s – view previous versions of standard. If the oil is exposed to severe nitration conditions, the nitration products in the astm e2412 will cause: For example, infrared spectroscopy cannot determine wear metal asrm or any other type of elemental analysis.
No other units of measurement are included in this standard. Astm e2412 the oil is exposed to severe nitration conditions, the nitration products in the oil will cause:.
