The Aluminum Beaker Oxidation Test is one of the tests specified for MERCONtm service ATF. The test is now being run at independent laboratories. Passing this and other specified tests is part of the process required to obtain a licence to describe an ATF as MERCONtm.
The performance of test facilities at independent laboratories has been monitored by evaluating test data obtained with reference ATFs provided by Ford. The data so obtained, together with data obtained at Ford and other laboratories, have been used to generate a statistically significant data base. This data base has been used to better define test repeatability and reproducibility and thus provide an improved basis for monitoring the performance of test facilities.
This paper provides a summary of the test procedure, reviews the data supporting the validity of the test, and presents information on the repeatability and reproducibility of the test method.
