Standard Test: Gearbox or bearing oils
Although contamination by dirt and water should be closely monitored in manual transmissions, differentials, final drives and planetaries, the biggest concern for these systems is the type of wear occuring.
The test includes:
Elemental Metals (24) by ICP (or Spectroscopy)
Elemental Analysis, or Spectroscopy, identifies the type and amount of wear particles, contamination and additives. Determining metal content can alert you to the type and severity of wear occurring in the unit. Measurements are expressed in parts per million (ppm). It provides rapid screening of used oils for indications of wear.
Water % by Crackle (Karl Fischer if Crackle is Positive)
To detect the presence of water in lubricating oil. Water contamination is detrimental to any lubricant.
Viscosity @ 40°C or 100°C
ASTM test uses a constant temperature bath. The efflux time is measured between two points. The viscosity is computed by using a calibration constant and the efflux time. Viscosity is reported in centistokes (cSt) at 40ºC or 100ºC.
Total Acid Number (TAN)
TAN is a measure of the total concentration of acids, both weak and strong, present in the oil. It is an indicator of oil health. Useful in monitoring acid buildup in oils due to depletion of antioxidants. High acid levels can indicate excessive oil oxidation or depletion of oil additives, which can lead to corrosion of the internal components.
The Particle Quantifier exposes the oil sample to a magnetic field. The presence of any ferrous (iron based) metal causes a distortion in the field, which is represented as the PQ Index. PQ Index correlates well with Direct Read Analytical Ferrography (large).
Sample bottle size: 90 ml.
