ASTM D6267-08
(Test Method)Standard Test Method for Apparent Viscosity of Hydrocarbon Resins at Elevated Temperatures
Standard Test Method for Apparent Viscosity of Hydrocarbon Resins at Elevated Temperatures
SIGNIFICANCE AND USE
This test method is used to measure the apparent viscosity of hydrocarbon resins at elevated temperatures. Elevated temperature viscosity values of a hydrocarbon resin may be related to the properties of coatings, adhesives and the like, containing such a resin.
For hydrocarbon resins, values of apparent viscosity will usually be a function of shear rate under the conditions of test. Although the type of viscometer described in this test method operates under conditions of relatively low shear rate, shear rate depends on the spindle and rotational speed selected for a determination; therefore, comparisons between apparent viscosity values should be made only for measurements made with similar viscometers under conditions of equivalent shear rate.
SCOPE
1.1 This test method covers the determination of the apparent viscosity of hydrocarbon resins having apparent viscosities up to 2,000,000 millipascal seconds (mPa·s) (Note 1) at temperatures up to 300°C (572°F).
Note 1—The SI unit of (dynamic) viscosity is the pascal second. The centipoise (cP) is one millipascal second (mPa·s) and is frequently used as a viscosity unit.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 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 determine the applicability of regulatory limitations prior to use.

4.1 The viscometer described in this test method can be used to determine the apparent viscosity of hydrocarbon resins at

viscometer. The torque on a spindle rotating in a thermostatted sample holder containing a small amount of sample is used to
measure the relative resistance to rotation. A factor is applied to the torque reading to yield the viscosity in mPa·s.
