Coordinating Support of Fuels and Lubricant Research and Development (R&D) 2, Delivery Order 0001: Water Separation Methods Study
Abstract
An aircraft turbine fuel Water Separation Methods validation program has been completed. In the study water separation methods measurements were for the first time experimentally compared against actual coalescence test results. This program was part of an extended study both of ways to improve the ASTM D 3948 MSEP test method and of the effectiveness of other water separation test methods. The effect of fuel quality on coalescence was measured in the Navy Coalescence Tester (NCT) using jet fuel field samples and jet fuel samples prepared to simulate additive and contamination effects. The jet fuels evaluated in the NCT were then tested using the various water separation test methods, and the results compared against the actual coalescence results. The Interface Rating for the ASTM D 1094 Water Reaction Test was found to be non-responsive to any change in fuel coalescence quality. Thus, the D 1094 Interface rating results from this study clearly fail to show any evidence of test validity. The other test methods evaluated all showed a response to variations in fuel coalescence quality. Results of regression analyses of the other water separation methods test results against NCT continuous coalescence times were used to statistically compare the effectiveness of various tests.
