1.1 ,These test methods cover the measurement of the viscosity of Newtonian and non-Newtonian liquids. These test methods are applicable to liquids having viscosities in the range from 5 ,×, ,10^−,4 to 10³ Pa·,s (0.5 to 10⁶ cP). The shear rate range is dependent upon the needle used and viscosity of the liquid and may vary from 10^−,4 to 10³ s^−,1. With an extension bar and applied weight, a shear rate of 10⁴ s^–,1 may be achieved.
