1.1 This test method covers the determination of viscosity of paints, varnishes, lacquers, and related liquid materials by dip-type viscosity cups. This test method is recommended only for viscosity control work within one plant or laboratory and should not be used to check compliance with specifications.

1.2 Viscosity cups are designed for testing of Newtonian and near-Newtonian liquids. If the test material is non-Newtonian, that is, shear-thinning or thixotropic, another method, such as Test Methods D2196, should be used.

1.3 This standard does not purport to address all of the safety problems, 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.
