ASTM D5226-21

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
Note 1: There is no known ISO equivalent to this standard.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
