Evaluation of Coking Propensity of Aviation Lubricants Using the Hot Liquid Process Simulator (HLPS) Single Phase Flow Technique ARP5996A

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 3.00 mg.
