3.i Aged Oil Low Temperature Viscosity,柠檬怎么保存
Aged oil low temperature viscosity must be measured on the final formulation, this includes ba oil and additive combination being licend, for each viscosity grade by either ROBO or IIIGA
Measure CCS viscosity of the EOT ROBO or IIIHA sample at the CCS temperature corresponding to original viscosity grade.
Aged Oil Low Temperature Viscosity ROBO Test, ASTM D7528

a) If CCS viscosity measured is less than or equal to the maximum CCS viscosity
specified for the original viscosity grade, run ASTM D4684 (MRV TP-1) at the MRV temperature spe
cified in SAE J300 for the original viscosity grade.
b) If CCS viscosity measured is higher than the maximum viscosity specified for the
original viscosity grade in J300, run ASTM D4684 (MRV TP-1) at 5°C higher temperature (i.e., at MRV temperature specified in SAE J300 for the next higher viscosity grade).
c) The EOT ROBO sample must show no yield stress in the D4684 test and its D4684travel
viscosity must be below the maximum specified in SAE J300 for the original viscosity grade, or the next higher viscosity grade, depending on the CCS viscosity, as outlined in a) or b) above.
