This standard is subject to revision at any time by the dd2170 technical committee and must be reviewed every five years and if not revised, either reapproved or withdrawn. The time is measured for a fixed volume of liquid to flow under gravity through the capillary of a calibrated viscometer under a reproducible driving head and at a closely controlled and known temperature inside a viscosity bath.

Rinse the ice with distilled water and shave or crush into small pieces, avoiding direct contact with the hands or any chemically unclean atm. A charge of the erythrocyte test by automated method. The values given in column 3 are the limits that should not be exceeded by the difference between the results of two properly conducted tests. The kinematic viscosity determined value is the product of the measured flow time and the calibration constant of the viscometer.

See Annex A1 for the method of calculation. As the ice melts, drain off some of the water and add more crushed ice. Purchase orders should be addressed to the Cannon Instrument Co. Why is the kinematic viscosity of asphalts bitumens important to know? After allowing the sample to attain bath temperature see A2. This error can be as much as one or two thermometer divisions. This density value is equivalent to a specific gravity of 1.


Calibrated viscometers are available from a number of commercial suppliers.

ASTM D2170/D2170M – 10

If the sample is poured at a temperature above test temperature, wait 15 min for the sample in the viscometer to attain bath temperature and add more sample to overflow slightly into bulb K.

Physical and Chemical Properties. Dry the viscometer by passing a slow stream of filtered, dry air through the viscometer for 2 min, or until the last trace of solvent is removed. The kinematic viscosity characterizes flow behavior. The achieved improvement was found to be dependent on polymer molecular weight. Results showed that the inclusion of PMMA polymer in asphalt binder has significantly improved its properties.

The bath is fitted with a double window of which the front pane is detachable for cleaning purposes. Select also a standard viscometer of known C constant. See Annex A1 for the method of calculation.

ASTM D/DM – 10 – Standard Test Method for Kinematic Viscosity of Asphalts (Bitumens)

In the IP this test method is under the jurisdiction of the Standardization Committee. If the sample may contain lint, solid particles, etc.

Introduce sample through tube N taking care not to wet the sides of tube N, into the cross-arm D until the leading edge stands within 0.


If the ratio is not constant, the liquid is non-Newtonian. Current edition approved Oct.

Reverse-flow viscometers are used for the measurement of kinematic viscosities of opaque and transparent liquids up to cSt. Failure to correct for gravity can result in errors of 0. Why should you use a Tamson Viscosity bath to measure the kinematic viscosity of asphalts bitumens? A number in parentheses indicates the year of last x2170.

ASTM D Standard

The kinematic viscosity characterizes flow behavior. C2 5 the calibration constant in the testing ast, C 1 5 the calibration constant in the calibrating laboratory, 5 the acceleration of gravity at the testing laboratory, g2 and 5 the acceleration of gravity at the calibrating laborag1 tory. D — 95 Designation: Introduce sufficient sample through tube N to completely fill bulb D, overflowing slightly into overflow bulb K. When thermometers are completely submerged, corrections for each individual thermometer based on calibration satm conditions of complete submergence must be asym and applied.

Firm supports for the viscometer shall be provided, or the viscometer may be an integral part of the bath. If the test temperature differs from the fill temperature, the viscometer constant is calculated as follows: View as Grid List. The ice point reading shall be expressed to the nearest 0.
