1. Test Monitoring Center Report to the Mack Test Surveillance Panel
January 23, 2007
San Antonio, TX

2. Reference Oil Testing Summary
T-8 Test Activity
Very Low
1 calibrated lab
2 calibrated stands
Issue: Lab(s) now without reference oil!!

3. Options (assuming the T-8 must live)
T-8 Reference Oil Issue
Options (assuming the T-8 must live)
Use T-11 as a replacement
slow to develop and not much energy so far
Voluntarily re-distribute remaining
has already been requested
success far from certain and can’t be forced
Get a different reference oil
most likely the best fit

4. TMC 1005-2 as T-8 Reference Oil
Positives
Five T-8 test results on 1005
Plenty available
Labs would be able to run immediately

5. TMC 1005-2 as T-8 Reference Oil
Negatives
Data is old (9 years)
Data is on a previous blend
Data is incomplete
Relative Viscosity (100% Shear) data doesn’t exist
Causes problems determining SAs (but not calibration status)

6. TMC 1005-2 as T-8 Reference Oil
Possibilities
Targets
VI38 (mean & stdev) = 5.85 & 0.72
RV48 (mean & stdev) = 2.09 & 0.15
RV2 - none
Control Charts
Suggest temporary expansion of Shewhart K to 2.00 until five tests
Either suspend or freeze current RV2 SAs

7. Reference Oil Testing Summary
T-11 Test Activity
Moderate
5 calibrated labs
6 calibrated stands
Oil has been introduced
More on this in a few moments

8. T-11 Correction Factors – Soot and MRV
T-11 Top Ring Change in May ’05
Total of 34 tests
30 tests on 820-2
4 tests on 820-3
Current CFs were set at 20 tests on new hardware (oil 820-2)

9. T-11 Correction Factors

10. T-11 Correction Factors
Do we update (and possibly freeze) the correction factors for Soot at 12 cSt and MRV based on 30 tests?

11. T-11 Reference Oil Update
TMC has been introduced
4 tests
3 passes, 1 fail (very mild on Soot at 12)
TMC will update as data comes in
No new tests expected until April

12. T-11 Reference Oil Update

13. Reference Oil Testing Summary
T-12 Test Activity
Low
6 calibrated labs
9 calibrated stands
Test targets nearing update (n = 19)
Sure to require significant discussion

14. Mack SP Items for Consideration
T-8 & T-11 Fuel Sulfur Measurements
QC measurements (not fuel spec sheet)
D 129 “or equivalent” (Sept. ’05)
not specific enough, undefined
D 129, D2622, D 4294, or D 5453
under consideration?
if no action, then D 129 only

15. Mack SP Items for Consideration
T-12 Piston Deposits
Currently mandatory
originally asked for in case C13 was a no-go
Mack SP voted to remove (3-1-9)
Change generates an Information Letter
Negative must be addressed before change is effective

16. Mack SP Items for Consideration
T-11 New Stand Definition (Sect. 11.4)
Time limit
Currently shown as one year from cal test
Conflicts with:
Meeting minutes (Feb. ’05) and LTMS doc
Suspect clerical error
Suggest change to “one year from cal expiration”

17. Mack SP Items for Consideration
T-11 Soot Calculations
Soot at 4, 12, and 15 cSt
Linear Interpolation
NOT specified in Section 11.6

18. Mack SP Items for Consideration
T-11 Soot Calculations
Current
11.6 Test Results—The test results are Soot Content at 4 cSt Viscosity Increase (%), Soot Content at 12 cSt Viscosity Increase (%), Soot Content at 15 cSt Viscosity Increase (%), and MRV Viscosity (cP)

19. Mack SP Items for Consideration
T-11 Soot Calculations
Suggested Fix
11.6 Test Results—The test results are Soot Content at 4 cSt Viscosity Increase (%), Soot Content at 12 cSt Viscosity Increase (%), Soot Content at 15 cSt Viscosity Increase (%), and MRV Viscosity (cP).
Use linear interpolation for calculating soot contents (at a given viscosity increase), using new oil 90-pass DIN shear viscosity result as the minimum viscosity (sections and )
Renumber following sections as appropriate ( to ).

20. T-12 to T-10 Merit Calculation
Action Item Update
T-12 to T-10 Merit Calculation
JAC asked to investigate where this should live
Answer: T-12 test method
BUT!!!
not until ballot clears Sub. B
Reports forms already updated
