Standard Test Methods for Viscosity of Materials by a Falling Needle Viscometer

Organization: ASTM International
Publication Date: 10 June 1998
Status: inactive
Page Count: 5
ICS Code (Measurement of volume, mass, density, viscosity): 17.060
scope:

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 X 10 -4 to 10 Pa[dot]s (0.5 to 10 cP). The shear rate range is dependent upon the needle used and viscosity of the liquid and may vary from 10 -4 to 10 s -1 .

1.2 The yield stress of liquids having this property may also be determined.

1.3 These test methods consist of determining liquid viscosities of Newtonian and non-Newtonian fluids (clear or opaque) by measuring the steady-state (constant) or terminal velocities of cylindrical needles as they fall through the test liquid under the influence of gravity. Yield stresses of non-Newtonian liquids may be measured using the same procedure.
