Standard Test Method for Kinematic Viscosity of Asphalts

Category

قطاع النفط والغاز Oil and Gas Sector

Scope

1.1 This test method covers procedures for the determination
of kinematic viscosity of liquid asphalts, road oils, and
distillation residues of liquid asphalts all at 60 °C [140 °F] and
of liquid asphalt binders at 135 °C [275 °F] (see table note,
11.1) in the range from 6 to 100 000 mm2/s [cSt].
1.2 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 binders
at 135 °C [275 °F] only in the viscosity range from 30 to 6000 mm2/s
[cSt].
NOTE 2—Modified asphalt binders or asphalt binders that have been
conditioned or recovered are typically non-Newtonian under the conditions
of this test. The viscosity determined from this method is under the
assumption that asphalt binders behave as Newtonian fluids under the
conditions of this test. When the flow is non-Newtonian in a capillary
tube, the shear rate determined by this method may be invalid. The
presence of non-Newtonian behavior for the test conditions can be verified
by measuring the viscosity with viscometers having different-sized capillary
tubes. The defined precision limits in 11.1 may not be applicable to
non-Newtonian asphalt binders.
1.3 Warning—Mercury has been designated by the 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 mercurycontaining
products. See the applicable product Material
Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) for
details and the EPA’s website—http://www.epa.gov/mercury/
faq.htm—for additional information. Users should be aware
that selling mercury, mercury-containing products, or both, in
your state may be prohibited by state law.
1.4 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.
1.5 The text of this standard references notes and footnotes
that provide explanatory material. These notes and footnotes
(excluding those in tables and figures) shall not be considered
as requirements of the standard.
1.6 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, health, and environmental practices and determine
the applicability of regulatory limitations prior to use.
1.7 This international standard was developed in accordance
with internationally recognized principles on standardization
established in the Decision on Principles for the
Development of International Standards, Guides and Recommendations
issued by the World Trade Organization Technical
Barriers to Trade (TBT) Committee.
