Evaluation of Fouling Propensity of Aviation Lubricants Using the Mixed-Phase Flow Technique (High-Temperature Deposition Test)

2023-10-05
CURRENT
ARP8462
The high-temperature deposition test (HTDT) method is designed to evaluate the deposition and degradation characteristics of turbine lubricants when stressed under mixed-phase flow conditions found in certain parts of aviation gas turbine engines. This method is applicable to lubricants that form deposits in the range of 0.1 to 100 mg during the course of a test.

Evaluation of Coking Propensity of Aviation Lubricants in an Air-Oil Mist Environment using the Vapor Phase Coker

2014-04-03
CURRENT
ARP5921
This method is designed to evaluate the coking propensity of synthetic ester-based aviation lubricants under two phase air-oil mist conditions as found in certain parts of a gas turbine engine, for instance, bearing chamber vent lines. Based on the results from round robin data in 2008–2009 from four laboratories, this method is currently intended to provide a comparison between lubricants as a research tool; it is not currently a satisfactory pass/fail test. At this juncture a reference oil may improve reproducibility (precision between laboratories); a formal precision statement will be given when there is satisfactory data and an agreed on, suitable reference oil if applicable.

Compatibility of Turbine Lubricating Oils

2023-05-01
CURRENT
ARP7120
This method is used for determining the compatibility of a candidate lubricant with specific reference lubricants. The reference lubricants to be used will typically be mandated by the owner of the product specification against which the candidate lubricant is being compared. This method is split into two procedures (Procedure A and Procedure B) with a summary of each procedure contained in Section 4.
