Subject:	Unapproved minutes of the December 20, 2005 meeting.
Attendance - Jim Gutzwiller; Jim Matasic; Jeff Clark; Jim Moritz; Charlie Passut; Wim Van Dam (Chairman); Greg Shank; Riccardo Conti; Scott Richards; Mark Cooper; Ron Buck; Ken Goshorn; Pat Fetterman (Secretary)

Wim called the meeting to order and he asked Jeff Clark to review the issue regarding LTMS targets.
Jeff indicated that he is currently working with two different sets of targets for the liner wear parameter, and that situation is untenable long term. Currently, stand targets are based on arithmetic means and standard deviations, while lab targets are based on the Matrix Model. All other test parameters are based on the least squares means and root mean square error. 
Following a lengthy discussion of how this situation could be resolved, Greg Shank made the following motion with a second from Jim Moritz:
The Panel agrees to evaluate this issue using the all of data following the next round of reference tests which have a timeframe of at least one test per lab by March 1. 2005. The motion passed with unanimous support.
Riccardo Conti noted that the allowable range of EOT oil consumption with TMC820-2 in the T-12 is significantly tighter than in the T-10. He also noted a possible trend toward increasing oil consumption as testing progressed. He proposed increasing the K value for Oil Consumption to match the value used for Ring Weight Loss. Again, following significant discussion, Riccardo made the following motion with a second by Scott Richards:
The Panel agrees to change the K value for the final oil consumption parameter from the current value of 1.8 to 2.4. This motion passed with (4) affirmative, (0) negative and (6) waive.
Scott Richards provided a background history of the T-12 development in support of a request to allow calibration of test stands which were used in pre-matrix testing using targets developed from the (4) runs using TMC820-2 which were run to the correct test procedure. Jeff Clark noted that this change would impact the targets and control charts of all labs involved.
While the group was involved in active debate over how and why this would occur, Jim Rutherford calculated (twice) the revised targets and circulated them to the group. The final revised targets are:

Parameter       lnPb       lnPb2       CLW       TRWL       lnOC
Target            3.0269    2.1647      23.2         102          4.277
Std. dev.        0.2034    0.1074       4.5           15            0.095

After reviewing these targets with all labs, Wim re-called the following motion:
To develop "old ring" targets for TMC820-2 using only the (4) pre-matrix tests which were run with the correct procedure and include the impact of adding these tests on the control charts of all labs. This motion passed with (5) affirmative, (0) negative and (5) waive.
Jeff Clark agreed to redo all lab control charts and send out revisions ASAP.

The next meeting (probably teleconference) will be at the call of the Chairman to address T-12 to T-10 correlation data and the formal addition of low temperature pumpability limits on the 180 hour sample from the T-11 test.
