ASTM D1823-16

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: D1823 − 95 (Reapproved 2009) D1823 − 16
Standard Test Method for
Apparent Viscosity of Plastisols and Organosols at High
1
Shear Rates by Extrusion Viscometer
This standard is issued under the fixed designation D1823; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope Scope*
1.1 This test method covers the measurement of plastisol and organosol viscosity at high shear rates by means of an extrusion
viscometer.
1.2 Apparent viscosity at low shear rates is covered in Test Method D1824.
1.3 The values stated in SI units are to be regarded as standard. The values in parentheses are given for information only.
1.4 This standard does not purport to address the safety concerns 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 4575-1985 in title only. The content is significantly different.standard and ISO 4575-2007 address the same
subject matter, but differ in technical content.

3. Summary of Test Method
3.1 The sample is conditioned to the proper temperature, placed into an extrusion chamber, and extruded under standard
conditions. The viscosity is calculated from the extrusion pressure and the rate of flow through the orifice.
4. Significance and Use
4.1 The suitability of a dispersion resin for any given application is dependent upon its viscosity characteristics.
4.2 The extrusion viscosity defines the flow behavior of a plastisol or organosol under high shear. This viscosity relates to the
conditions encountered in mixing, pumping, knife coating, roller coating, and spraying processes.
