STANDARD published on 1.3.2026
The information about the standard:
Designation standards: SAE ARP5921A
Publication date standards: 1.3.2026
SKU: NS-1263670
Country: American technical standard
Category: Technical standards SAE
Annotation of standard text SAE ARP5921A :
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 to 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.
