The quality of the results produced by this standard are dependent on the competence of the personnel performing the procedure and the capability, calibration, and maintenance of the equipment used. Agencies that meet the criteria of Specification D are generally considered capable of competent and objective testing, sampling, inspection, etc. Users of this standard are cautioned that compliance with Specification D alone does not completely ensure reliable results.
Reliable results depend on many factors; following the suggestions of Specification D or some similar acceptable guideline provides xstm means of evaluating and controlling some of those factors.
ASTM D – 07 Standard Test Method for Viscosity of Asphalts by Vacuum Capillary Viscometer
It is applicable to materials having viscosities in the range from 0. Modified asphalt binders or asphalt binders that have been conditioned or recovered are typically non-Newtonian under the conditions of this test.
The apparent viscosity for non-Newtonian asphalt binders varies with shear rate. When the flow is non-Newtonian in a capillary tube, the shear rate determined using this test method may be invalid. The presence of non-Newtonian behavior for the test conditions of this test can be verified by measuring the viscosity with viscometers having different-sized capillary tubes or with different pressure heads.
The defined precision limits in Section 11 may not be applicable to non-Newtonian asphalt binders. Test Method D may be a more applicable method for testing non-Newtonian asphalts. 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 astj may result in nonconformance with the standard. Mercury, or its vapor, may be hazardous to health and corrosive to materials.
