ASTM D3427 Air Release Properties Of Hydrocarbon Based Oils
Agitation of lubricating oil with air in equipment, such as bearings, couplings, gears, pumps, and oil return lines, may produce a dispersion of finely divided air bubbles in the oil. If the residence time in the reservoir is too short to allow the air bubbles to rise to the oil surface, a mixture of air and oil will circulate through the lubricating oil system. This may result in an inability to maintain oil pressure (particularly with centrifugal pumps), incomplete oil films in bearings and gears,and poor hydraulic system performance or failure.

ASTM D8184 Particle Quantifier Instrument for Ferrous Wear Debris
KN-8184 Particle Quantifier Instrument for Ferrous Wear Debris conforms to ASTM D8184 Standard Test Method for Ferrous Wear Debris Monitoring in In-Service Fluids Using a Particle Quantifier Instrument. This test method is intended for the application of PQ magnetometry in assessing the progression of wear in machinery, for example, engines and gearboxes, by trending the mass of ferrous debris in samples of lubricating oils or greases.

ASTM D94 Saponification Number Of Petroleum Products
A known mass of the sample is dissolved in a suitable solvent, such as butanone (methylethylketone), xylenes, or Stoddard Solvent, or a combination thereof (Warning— Extremely flammable. Vapors can cause flash fire), and is heated with a known amount of alcoholic potassium hydroxide (KOH). The excess alkali is titrated with standard acid, and the saponification number is calculated.

ASTM D6082 High Temperature Foaming Characteristics Of Lubricating Oils
The tendency of oils to foam at high temperature can be a serious problem in systems such as high-speed gearing, high volume pumping, and splash lubrication. Foaming can cause inadequate lubrication, cavitation, and loss of lubricant due to overflow, and these events can lead to mechanical failure

FTIR Spectrometer for Lubricants
Lubricant oils exhibit various chemical changes during their life time. This starts by simple changes such a fuel dilution of the fuel used or the uptake of soot (ASTM E2412) from the combustion. Numerous chemical reactions with combustion products lead to oxidation (ASTM D7414), nitration (ASTM D7624) or sulfation (ASTM D7415) of the lubricant and can be summarized as degradation products. To enable cycle times known from modern lubricants a wide variety of additives are added. These additives are used up during operation.

ISO 6617 Ageing Characteristics Tester
The oxidation stability test of mineral transformer oils is a method for assessing the amount of sludge and acid products formed in a transformer oil when the oil is tested under prescribed conditions. Good oxidation stability is necessary in order to maximize the service life of the oil by minimizing the formation of sludge and acid.
