该方法旨在评估合成酯基航空润滑油在单相流条件下的结焦倾向，该条件在燃气轮机发动机的某些部件中发现，例如在轴承供油管中。本方法适用于本方法测定的结焦倾向在0.01至5.00 mg范围内的润滑剂。

This method is designed to evaluate the coking propensity of synthetic ester-based aviation lubricants under single phase flow conditions found in certain parts of gas turbine engines, for instance in bearing feed tubes. This method is applicable to lubricants with a coking propensity, as determined by this method, falling in the range 0.01 to 5.00 mg.
