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.

1.1These 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.

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

1.3These 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.

1.4The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.5This 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 determine the applicability of regulatory limitations prior to use.
