Title:Evaluation of Coking Propensity of Aviation Lubricants Using the Hot Liquid Process Simulator (Hlps) Single Phase Flow Technique
Issuing Committee:E-34 Propulsion Lubricants Committee
Scope: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.【英文标准名称】:Thermoplasticspipes-Longitudinalreversion-Testmethodandparameters
