    ASTM D6267 / D6267M

    Significance and Use

    5.1 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.

    5.2 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.

    1. 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 1The 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 either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

    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.
