September Found Ms. Thom Back in Denver for the SAE E34 & E38 Meetings
September 25-26, 2019 Cherry Creek, CO - Working on the alternative aviation gasoline development document for ASTM uncovered a potential "lost" consideration. From the beginning it was recognized that the interactions between the aviation gasoline and the piston engine oil needed to be considered. Because of the function of the engine oil in the pistons, the oil is routinely exposed to small amounts of the AvGas. This interaction has been considered in the ASTM Guide, D7826. But what had begun to slip through the cracks was the control on the oil itself. The technical content and requirements of the two oil standards, SAE J1899 "Lubricating Oil, Aircraft Piston Engine (Ashless Dispersant)" and SAE J1966 "Lubricating Oils, Aircraft Piston Engine (Non-Dispersant Mineral Oil)" have been the basically the responsibility of the US Navy. The original standards covering the oils were MIL-L-22851 and MIL-L6082, which were migrated to the SAE system in the early 1990s.
This has worked fine and there have been no issues with this status. But now the US Navy would like to relinquish primary responsibility for the content of the standard and the testing of potential new oils. To support this, the SAE committee responsible for these oils have begun reviewing the current document and the historical development to be able to move the testing requirements, both test method and results more overtly to the standards. Again, this is how the system is supposed to work. And it is no small challenge. But what Baere personnel came to realize was that this effort was happening AT THE SAME TIME as the considerations for testing of new AvGas formulations with the piston oils.
The result of this realization was to send our Sr. Staff Chemist to the E38 meetings in Denver with the understanding Baere may need to become a more active participant in SAE. Which we have done. So now we are going to be part of a smaller working group undertaking the challenge of capturing how the industry got to where it is with aviation piston oils and what is important to test, measure, and report. This won't be easy, but we are looking forward to the effort!
Mixing Work and Pleasure
The International Association for the Stability and Handling of Liquid Fuels
In September Ms. Thom was a session chair and a participant in the biennial IASH Symposium held in Long Beach, CA. This is a meeting of all things liquid fuel, from Marine Diesel to fuel for nuclear power plants. And obviously some aviation related fuels along the way. Melanie was chair for the Microbiology session. And it went great! As always, the symposium was an impressive collection of presentations, networking, and trade show activities. For those of you who are members of IASH, the proceedings will be on our website soon. For you who want to know more, visit www.IASH.net.
We weren't allowed to take photos in the sessions themselves, but there is an award dinner that is a big deal. This year it was on the Queen Mary and we had to dress for dinner...
