Standard Test Method for Viscosity of Printing Inks and Vehicles by the Falling-Rod Viscometer
|Publication Date:||10 June 1999|
|ICS Code (Inks. Printing inks):||87.080|
1.1 This test method covers the procedure for determining the falling-rod viscosity of printing inks, vehicles, and similar liquids that are essentially nonvolatile and unreactive under ordinary room conditions.
1.2 For printing inks, which are typically non-Newtonian, this test method is applicable in the apparent viscosity range of about 10 to 300 P at a shear rate of 2500 s -1 . For Newtonian liquids, the applicable viscosity range is about 10 to 1000 P (1 P = 0.1 Pa[dot]s).
1.3 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. For specific hazard statements, see Section 8.
