Testing the Reserve Alkalinity: Base Number

Testing the Reserve Alkalinity: Base Number
Testing the Reserve Alkalinity: Base Number Base Number (BN) testing is very similar to AN testing, except that the properties are reversed.  The sample is titrated with an acidic solution to measure the oil’s alkaline reserve.  ASTM test methods D-2896 or D-4739 are most commonly used to measure BN.  Measuring the BN can help ensure…

Gauging Acidity: Acid Number

Gauging Acidity: Acid Number
Gauging Acidity: Acid Number Acid Number (AN) is an indicator of oil serviceability.  It is useful in monitoring acid build-up in oils due to the depletion of antioxidants. Oil oxidation causes acidic byproducts to form. High acid levels can indicate excessive oil oxidation or depletion of the oil additives and can lead to corrosion of…
