This European Standard specifies a procedure for the determination of kinematic viscosity at 40 °C in the range from 2 mm2/s to 6 mm2/s by calculation from dynamic viscosity and density of middle distillate fuels, fatty acid methyl ester fuels (FAME) and mixtures of these using the Stabinger-type viscosimeter.
The result obtained using the procedure described in this standard depends on the behaviour of the sample. This European Standard should be used predominantly on liquids whose shear stress and shear rate are proportional (Newtonian flow behaviour). However, if the viscosity changes significantly with the shear rate, comparison with other measuring methods is only permissible at similar shear rates.
