1.1 This test method covers the measurement of dynamic viscosity, density and derivation of kinematic viscosity of petroleum liquids, both transparent and opaque. The kinematic viscosity, , can be derived by dividing the dynamic viscosity, , by the density, , obtained at the same test temperature. 1.2 The result obtained from this test method is dependent upon the behavior of the sample and is intended for application to liquids for which primarily the shear stress and shear rate are proportional (Newtonian flow behavior). 1.3 The range of kinematic viscosity covered by this test method is from 0.5 mm2/s to 1000 mm2/s in the temperature range between 40 C to 120 C; however the precision has been determined only for fuels and oils in the range of 2.06 mm2/s to 476 mm2/s at temperatures of 40 C and 100 C (as stated in Section 12 on Precision and Bias). 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
