Since the early 1960s the Ball-on-Cylinder Lubricity Evaluator (BOCLE) test has been recognized as the best available method for providing a relative system of measurement of the lubricity properties of jet engine fuels. The technical effort described in this report was directed at refining and standardizing the (BOCLE) test. It focused on identifying variables suspected of affecting the test method precision. The Falex Ring was shown to significantly enhance BOCLE-test precision and eliminate many of the problems associated with the conventional AMS 6444 test cylinder. Test results showed that the source of the test ball can have a significant effect on BOCLE test results. SKF Swedish precision balls were found to provide optimum batch to batch consistency. Isopar M + 30 ppm DuPont DCI-4A was shown to be a reproducible fluid suitable for use as a standard reference fluid for BOCLE testing.
