If, however, the viscosity varies significantly with the rate of shear, different results may be obtained from viscometers of different capillary diameters.
NOTE 2: ISO 3104 corresponds to Test Method D445 – 03.ġ.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 rates are proportional (Newtonian flow behavior). NOTE 1: For the measurement of the kinematic viscosity and viscosity of bitumens, see also Test Methods D2170 and D2171. The dynamic viscosity, η, can be obtained by multiplying the kinematic viscosity, ν, by the density, ρ, of the liquid. Scopeġ.1 This test method specifies a procedure for the determination of the kinematic viscosity, ν, of liquid petroleum products, both transparent and opaque, by measuring the time for a volume of liquid to flow under gravity through a calibrated glass capillary viscometer. Thus, the accurate determination of viscosity is essential to many product specifications.
In addition, the viscosity of many petroleum fuels is important for the estimation of optimum storage, handling, and operational conditions. Scaffolding, Shoring and Anchoring Systems Testingĥ.1 Many petroleum products, and some non-petroleum materials, are used as lubricants, and the correct operation of the equipment depends upon the appropriate viscosity of the liquid being used.Propulsion System Simulation and Testing.Mechanical, Structures, Fatigue, and Load Testing.Lifting Equipment, Over-head & Mobile Cranes Testing.
