Minutes- 

T-10 / T-12 correlation -
Wim opened with a proposal that we spend about 50 minutes on the T-10 / T-12 correlation issues, and reserve the final 30 minutes for other Mack test issues. He aslo quickly reviewed the three proposals which are;
0) Reduced T-12 merits
0) Calculate T-10 from T-12
0) Revise merit system
Jim Rutherford offered that, while his proposal is, in his own words, "ugly", he still thinks it is the best use of all available data
Both Wim Van Dam and Bob Campbell reviewed their alternative proposals for a revised merit calculation, with Wim's approach concentrating on the candidate data, while Bob's approach centered on TMC820 data. Following a significant discussion of the three options, group consensus seemed to close around a "hybrid" approach to a new merit calculation which would use both TMC820 and candidate data. Wim agreed to draft a proposal for further discussion during a follow-on telecon on Thursday, the 30th.

T-10 stand calibration extension -
Jeff Clark indicated that the TMC would have serious concerns over a calibration extension, as it would, effectively, mean that the TMC is no longer monitoring the test. The greatest concern is not over lack of monitoring, but over the implications of that to outside groups such as API, ACC, ACEA and others…they must be alerted if  there is any change in the effective monitoring of this test. Following another signinicant discussion, a motion to extend the current calibration periods for the two stands involved passed with 8 positive and 1 negative responses.
Jeff immediately moved that the Panel chair should formally advise the HDEOCP, ACEA, EMA, API and ACC that the panel had taken this action to extend the calibration period of these two stands. This motion passed with unanimous support.

T-12 stand calibration extensions - 
Following a brief discussion, Jim Moritz moved that those T-12 stands which had run early calibration tests should have the "lost" tests added to the new calibration period. Jeff Clark will work with individual labs to work out the details of each extension. This motion also passed with unanimous support.

TMC820 reference oil resupply -
Jeff reported that the TMC is working with the oil supplier, and he expects to have a further update for tomorrow's meeting.
