Standard Practice for Injection Molding Test Specimens of Thermoplastic Molding and Extrusion Materials

Importancia y uso:

5.1 It is well known that plastic test specimens molded under different conditions can have significantly different properties. This practice is designed to minimize those differences by establishing operating protocols without being unnecessarily restrictive.

5.2 Always refer to the ASTM material specification or ISO designation for the material for recommended molding conditions. If not available, consult the material supplier.

5.3 This practice requires the use of adequate quantities of plastic material to find desirable operating conditions and to make the desired test specimens.
