The Evaluation of a Test Scheme for the Approval of Diesel Lubricity Additives for Refinery Use
The objective of this project was to define test criteria to ensure that the refinery application of
lubricity additives would be free from unwanted side-effects.
To satisfy these criteria a number of laboratory tests were selected and evaluated in `round robin' tests with respect to discriminating power and use within the participating laboratories.
Simultaneously maximum permitted deviations were determined, so that the properties of fuels treated with lubricity additve could be differentiated from base fuels. In addition boundary conditions for pure additives were established to guarantee satisfactoriy storage stability and application.
In total six test criteria with corresponding laboratory tests were established. In order to guarantee freedom from negative side effects with lubricity additives, these six chosen experimental criteria should form part of refinery requirements.
