IIIG LTMS V2 Review

1. IIIG LTMS V2 Review

2. LTMS V2 Review • Data Summary: • Includes 285 Chartable reference oil results from all test laboratories • Most recent chartable reference oil result included in data set is March 22, 2010 • Includes all ACLW data that is currently exhibiting a mild trend • All parameters (WPD, ACLW, & PVIS) are classified as “Primary”

3. LTMS V2 Review • Proposed Limits for IIIG LTMS v2 example: • Limits for ei & zi:

4. Invalid & Shortened Reference Periods • Current Unacceptable: • If Yi > 2 and SA = 0 (Re-Reference required) • If Yi < -2 and SA = 0 (Re-Reference required) • If |Yi| > 3 (Re-Reference required) • Current Shortened Reference Period: • If Yi > 2 and SA > 0 (18 candidates/reference) • If Yi < -2 and SA < 0 (18 candidates/reference)

5. Invalid & Shortened Reference Periods • Proposed: • If |ei| > 2.055 (Re-Reference required) & UI check • If |Yi – Yi+1|> 2.055 then apply undue influence constraint (Yi is adjusted such that ei = 2.055) • If |ei| > 1.73 (Shortened Reference Period 80%)

6. Extended Reference Periods • Extended Reference Period (Proposed): • If |ei| < 0.5 and previous test was acceptable, then extend 20% • If |ei|< 0.5 and |zi|< 0.5 and previous test was acceptable, then extend by 40%

7. IIIG calibration attempt summary: • Of the 289 total, 73.3% acceptable, 17.3% failed acceptance, and 9.4% were invalid

8. IIIG Alarm Summary (all labs & chartable results): • Below summarizes the unacceptable, reduced, and extended reference interval count for LTMS v1 & v2.

9. IIIG Alarm Summary (all labs & chartable results): • Below summarizes the unacceptable, reduced, and extended reference interval percentage for LTMS v1 & v2.

10. IIIG Alarm Summary (by lab): • Below summarizes the unacceptable, reduced, and extended reference interval count for LTMS v1 & v2 by test lab (285 Chartable test results).

11. IIIG RMSE for the PVIS parameter: • RMSE calculation is a function of the average deviation from the target and within lab variation.

12. IIIG Relative Pass limit of a Candidate test for the PVIS parameter:

13. IIIG RMSE for the WPD parameter: • RMSE calculation is a function of the average deviation from the target and within lab variation.

14. IIIG Relative Pass limit of a Candidate test for the WPD parameter (with a [GF-4] 3.5 limit):

15. IIIG RMSE for the ACLW parameter: • RMSE calculation is a function of the average deviation from target and within lab variation.

16. IIIG Relative Pass limit of a Candidate test for the ACLW parameter:

17. Undue Influence example for TPVIS (ei) data • Plot of ei data with no Undue Influence adjustment

18. Undue Influence example for TPVIS (ei) data • Circled results with “capped” adjustment (at +2.066 limit) • Result adjusted if |Yi – Zi-1| > 2.066 and |Yi – Yi+1| > 2.066

19. Undue Influence “Capped” Result Summary:
