ASTM D5226-16

Standard Practice for Dissolving Polymer Materials

SIGNIFICANCE AND USE
5.1 This practice embodies the specifications to describe the preparation of a polymeric solution.
SCOPE
1.1 This practice outlines the parameters applicable to the preparation of a polymeric solution, such as solvent, concentration, temperature, pressure, time, agitation, and heating mode.  
1.2 The proper use of this practice requires knowledge of solvents and their effect on polymeric materials.  
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.  
Note 1: There is no known ISO equivalent to this standard.

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
