This document specifies a procedure for the determination of dynamic viscosity (·) and density (Á) for the calculation of kinematic viscosity (½) of middle distillate fuels, fatty acid methyl ester fuels (FAME) and mixtures of these up to 60 % with middle distillate fuels, and lubricating oils including base oils, formulated oils, and synthetics, using a constant pressure viscometer. The range of kinematic viscosities covered in this test method is from 0,5 mm2/s to 2 000 mm2/s, with precision at 40 °C from 1,0 mm2/s to 1 286 mm2/s, and pr ecision at 100 °C from 3,0 mm2/s to 157 mm2/s. The result obtained using the procedure described in this document depends on the rheological behaviour of the sample. This document is predominantly applicable to 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.
