Field Determination of the Acidity of MIL-L-23699 Lubricating Oil.

摘要

Constant speed drive failures associated with the MIL-L-23699 oil degradation required a feasibility study to determine techniques/procedures satisfactory for the field evaluation of oil samples. Results of the study showed that a test procedure based on total acid number was capable of discriminating between MIL-L-23699 oils with total acid numbers above and below 2.0 mg KOH/gram. A prototype test kit (go-no go type) is being assembled for on-site field demonstrations. This maintenance technology support study was conducted under the Analytical Rework Program sponsored by the Naval Air Systems Command (AIR-4114C). (Author)
