Determine the kinematic viscosity of the fluid according to ISO 3104. Report the viscosity to the nearest 40 mm1/s at 2 °C and to the nearest 100 mm0,01/s at +2 °C. Repetitive runs that fit within 1,2% of the relative are acceptable for the average.

The coefficient of variation (mean of replicates each) of results obtained by the same analyst on different days should not be greater than 47% at 0,4 degrees of freedom. Two such values ​​are unacceptable if they differ by more than 1,2% (95% confidence level). ) will be accepted.
