T-12 Soot Window and Results on New Parts Batch
Intertek's recent T-12 on the new hardware missed the 100 hour soot window. Jim Moritz has sent soot samples to Lubrizol and Afton to verify soot measurements. Jeff mentioned that it is reasonable to include all valid soot measurements to determine the soot values, but that it isn't good to remove or "pick-n-choose" data. Further discussion on the soot window was tabled pending a final soot determination on Intertek's test. ExxonMobil will be going on test soon, the break-in is currently running. Data to date on the new parts batch is summarized in the table below.

Lab	A	B	D	F	G	
CLW	26.8	31.3	27.4		27.3	
TRWL	97	69	93		60	
Pb	27	29	22		23	
Pb 250-300	9	10	7		10	
OC	62.1	68.5	65.9		59.1	
Fe 100hr	66	70	58		56	
Fe 300hr	202	299	213		219	

New Rings for T-11
Consensus existed to immediately pursue a ring batch for the T-11 that is in the same porosity range as the previous batch(es). Greg Shank will consult with Ken Goshorn. Discussion ensued regarding using old parts for T-11 builds, but no other actions were taken.

Next Meeting(s)
A teleconference will be held Tuesday, October 14. A face-to-face meeting will be held once all the T-12 data is in, the date was set for October 23 in San Antonio.
