SAE ARP5088C PDF

The test method describes the procedure for determination of the total acid number (TAN) of new and degraded polyol ester and diester-based gas turbine lubricants by the potentiometric titration technique. The method was validated to cover an acidity range of 0.05 to 6.0 mg KOH g^-1. The method may also be suitable for the determination of acidities outside of this range and for other classes of lubricants.
