Standard Test Method for Viscosity and Yield of Vehicles and Varnishes by the Duke Viscometer
|Publication Date:||10 November 2000|
|ICS Code (Measurement of volume, mass, density, viscosity):||17.060|
|ICS Code (Paints and varnishes):||87.040|
This test method covers the procedure for determining the viscosity of
varnishes, ink vehicles, and
similar liquids that are essentially nonvolatile and unreactive under
ordinary room conditions
using the Duke Automated high-shear rod and collar
The instrument in this test method is similar in principle to the falling-rod viscometer described in Test Method D 4040 except that the collar is motor driven and the range of available shear stresses is considerably greater. This instrument is capable of measured and extrapolated viscosity and yield values provided the proper model is chosen for the given application. See Section 6 for the ranges of specified models.
The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
This standard does not purport to address all of the safety concerns, if any, that may be associated with its use. It is the responsibility of the user of this standard to establish any appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Footnote 2 - The sole source of supply of an automated high shear rod and collar viscometer known to the committee at this time is Duke Custom Systems, Inc., Pleasant View, TN. If you are aware of alternative suppliers, please provide this information to ASTM International Headquarters. Your comments will receive careful consideration at a meeting of the responsible technical committee,(Footnote 1) which you may attend.
Footnote 1 - This test method is under the jurisdiction of ASTM Committee D01 on Paint and Related Coatings, Materials, and Applications and is the direct responsibility of Subcommittee D01.37 on Ink Vehicles.
