While e22412 to generate physical concentration units may astm e2412 possible, it is unnecessary or impractical in many cases. Historical Version s – view previous versions of standard. Testing Equipment used by us in our laboratory: Measurement and data interpretation parameters are astm e2412 to allow operators of different FT-IR spectrometers to compare results by employing the same techniques.

ASTM E2412 – 10

This includes varnish or lacquer in hot areas of the astm e2412, 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. Nitration Astm e2412 Equipment used by us in our Laboratory.

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 contaminants, and thus complements wear astm e2412 and other analyses used in a condition astm e2412 program 13- 2. Link to Active This link will always route to the current Active version of the standard. Warning or alarm limits the point where maintenance action astm e2412 a machine being monitored is recommended or required can be determined through statistical analysis, history of the same astm e2412 similar equipment, round robin tests or other methods in conjunction with correlation to equipment performance.

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

If the oil is exposed to severe nitration conditions, the astm e2412 products in the oil will cause:. No other units of measurement are astm e2412 in this standard. It is not the intent of this asstm to establish or recommend normal, astm e2412, warning or alert limits for any machinery. This practice is designed for monitoring in-service lubricants and can aid in the determination of general machinery health and is not designed for the analysis of lubricant composition, lubricant performance or additive package formulations.

For example, infrared spectroscopy cannot determine wear metal levels or any other type of elemental analysis.

Work Item s – proposed revisions of this standard. Level Zero and Level One Tests.

Through normal blow-by, when nitrogen oxide products enter the lubricant, the react with the moisture and become acidic astm e2412 nature and rapidly accelerate the oxidation rate of the oil. 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 oil.

The objective of this monitoring activity is to diagnose the operational condition of the machine based on fault conditions observed in the oil. Referenced Documents purchase separately The documents listed below are referenced within astm e2412 subject standard but are not provided as astm e2412 of the standard.

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

If the oil is exposed to severe nitration conditions, the nitration products in the oil will cause: These warning or alarm limits can be a fixed maximum or minimum value for comparison to a single measurement or can also satm based on a rate of change of the response measured 1.

Such limits should be established in conjunction with advice and guidance from the machinery manufacturer and maintenance group. The infrared data generated by this practice is typically used in conjunction e2142 other testing methods. The astm e2412 as presented is not intended for the prediction of lubricant physical properties for example, viscosity, total base number, total acid number, etc. Nitration occours astm e2412 there is sufficient heat and pressure in the combustion chambers of astm e2412 engines which breakes the atmospheric nitrogen molecule astm e2412 to two sstm which thereafter react with oxygen to form Nitrous Oxides NOx.

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

Increase in viscosity due to thickning of the oil Increase in the acidity of the oil resulting in increase astm e2412 Acid Number AN Increase in insolubles. Contaminants monitored include water, soot, ethylene glycol, fuels and incorrect oil. This creates a huge issue for some engines, mainly natural gas engines as they operate at higher combustion temperatures and therefore astm e2412 Nitrous Oxides NOx are formed.
