The suitability of a dispersion resin for any given application process is dependent upon its viscosity characteristics.

The viscosity defines the flow behavior of a plastisol or organosol under low shear. This viscosity relates to the conditions encountered in pouring, casting, molding, and dipping processes.

1.1 This test method covers the measurement of plastisol and organosol viscosity at low shear rates.

1.2 Apparent viscosity at high shear rates is covered in Test Method D1823.

1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.4 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.

Note 1—This test method resembles ISO 3219-1977 in title only. The content is significantly different.
