Standard Test Method for Kinematic Viscosity of Asphalts (Bitumens)
|Publication Date:||1 June 2010|
This test method covers procedures for the determination of kinematic viscosity of liquid asphalts (bitumens), road oils and distillation residues of liquid asphalts (bitumens) all at 60°C [140°F] and of asphalt cements at 135°C [275°F] (Note 1) in the range from 6 to 100 000 mm2/s [cSt].
Results of this test method can be used to calculate viscosity when the density of the test material at the test temperature is known or can be determined. See Annex A1 for the method of calculation.
NOTE 1-This test method is suitable for use at other temperatures and at lower kinematic viscosities, but the precision is based on determinations on liquid asphalts and road oils at 60°C [140°F] and on asphalt cements at 135°C [275°F] only in the viscosity range from 30 to 6000 mm2/s [cSt].
Warning-Mercury has been designated by United
States Environmental Protection Agency (EPA) and many state
agencies as a hazardous material that can cause central nervous
system, kidney and liver damage. Mercury, or its vapor, may be
hazardous to health and corrosive to materials. Caution should be
taken when handling mercury and mercury containing products. See
the applicable product Material Safety Data Sheet (MSDS) for

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.
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.
