Sample Type Definitions

Particle Count = Number of particles in specified size range per fluid volume (usually per ml or 100ml).

Viscosity = Kinematic viscosity is a measure of a fluids resistance to flow under gravitational forces.

Neutralization = Total Acid Number (TAN) Applied to industrial (non crankcase) oils, the (TAN) is a measure of total acid concentration of the oil.

Neutralization Number = Total Base Number (TBN) Applied primarily to crankcase applications, (TBN) measures the reserve alkalinity (additives) of an oil.

Fourier Transform Infrared (FTIR) Spectroscopy = FTIR is the method that provides a rapid means to monitor multiple oil parameters simultaneously.

Ferrous Density = An increase in the population of large (>5 microns) ferrous particles usually suggest the presence of an abnormal wear condition and should serve as a warning of failure.

Analytical Ferrography = An exception diagnostic test, it involves the analysis of debris deposited onto a ferrogram slide of filtergram membrane.

Water Content by Karl Fisher = The Karl Fisher test is usually performed after the sample is screened with the hot-plate "crackle test" of FTIR.

Elemental Spectroscopy = This test quantifies the presence of dissolved and some undissolved inorganic materials by element in the oil.

Flash Point Test = The flash point identifies the presence of volatile molecules from fuel and other flammable contaminants.

Rotating Bomb Oxidation Test(RBOT) = This test method utilizes an oxygen-pressured bomb (vessel) to evaluate the oxidation stability of the sample of oil at high temperatures in the presence of water and a copper catalyst oil.
