Transcription

1 To: Cc: API Lubricants Group Lubricants Group Mailing List API Ballot Table F-** Groups II, III and IV Viscosity Read-Across: LSPI Test (ASTM Dxxxx ) During the March 14, 2018 Lubricants Standards Group Meeting the LSG considered a motion to ballot the Table F-** Groups II, III and IV Viscosity Read-Across: LSPI Test (ASTM Dxxxx ) The Motion proposed the following Tests required for interchange. Table F-** Groups II, III and IV Viscosity Read-Across: LSPI Test (ASTM Dxxxx ) Can Be Read-Across 1 to: Test Run on 0W-16 0W-20 0W-30 5W-20 5W-30 10W-30 0W-16 NA X X X X X 0W-20 X NA X X X X 0W-30 X X NA X X X 5W-20 X X X NA X X 5W-30 X X X X NA X 10W-30 X X X X X NA 1 Tested formulations containing Group I and/or Group V stocks must contain an equal amount of the same base stock in the finished oil blend for application of viscosity grade read-across. Bracketing two passing formulations for a given technology may be used to waive additional viscosity grade testing. VGRA is allowed if the candidate s base oil viscosity at 100 C falls within the range of the base oil viscosity at 100 C of the 2 passing formulations. Additionally, the viscosity modifier content must be no more than 1.5 times higher than the highest viscosity modifier content in the oils used to support the VGRA bracket. (This approach applies to formulations with base stock Group II, Group III and Group IV. Oils containing Group I and/or Group V base stocks must contain an equal amount of the same base stock in the finished oil blend for application of viscosity grade readacross.) Example: Matrix Oil 1 Matrix Oil 2 Candidate Oil A Candidate Oil B Base Oil 100 C, cst Dxxxx Seq. IX LSPI Pass Pass Test Required? No Yes Reason Formulation falls within the base oil viscosity range Formulation does not fall within the base oil viscosity range

2 After review and discussion, the LSG agreed by voice vote to Ballot Ballot Table F-** Groups II, III and IV Viscosity Read-Across: LSPI Test (ASTM Dxxxx ) into API 1509, Annex F. A copy of the Motion is included in the documentation. Draft of Annex F, Ballot Table F-** Groups II, III and IV Viscosity Read-Across: LSPI Test (ASTM Dxxxx ) is provided to show how the Seq. IX equivalency will be included in API The Analysis the Seq. IX Test data are provided to support Motion to accept Ballot Table F-** Groups II, III and IV Viscosity Read-Across: LSPI Test (ASTM Dxxxx ) into Annex F. Lubricants Group Members should use the API eballot System to cast their vote and make comments. The eballot Link is: The Lubricants Group Member votes will be counted, and all received comments reviewed and considered before the ballot results are final. Non-Lubricants Group Members should comment on the Ballot Motion using the eballot system. The eballot Link is: All comments on the Ballot Motion will be reviewed before the ballot results are final. This eballot will close on March 30. All Votes and/or Comments must be received by the close date. If approved the Effective Date of the Change to API 1509 will March 15, 2018.

Regressed LSPI [Sqrt(AVPIE + 0.5)] on: Technology BO API Gp BS Slate[BO API Gp] BOV100 Rel. VM The matrix was not designed to estimate interaction effects and, due to, among other issues, multicollinearity concerns, interactions are not included in the regression analysis. Correlation of BO and FO properties: BOV100 and Finished Oil Noack are highly correlated and should not be included in the same model. Likewise, BO VI and BO API Gp are highly correlated and should not be included in the same model. 6
