The document is a recommended guide for evaluating new or replacement test methods. It considers applicability, suitability, accessibility, and return on effort. Particular emphasis should be placed on completing the “strategy definition” portion of this document (Stage 2), to capture all relevant process stages and complete in a recognizable order for any specific development project. The overall process should: 1 address the rationale behind testing; 2 result in a thorough review of whether a test is fit for purpose; 3 act as a pathway for vetting if a test should be added to AS5780. If, in any project, this process is not an exact fit, users should feel free to adjust, as necessary. The process provides the following stages:

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.

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.
