Standard Specification for Polypropylene and Extrusion Materials

 
ASTM D4101


 

Scope:
This specification defines pertinent properties, test methods, parameters and sample preparation for the evaluation of polypropylene for molding and extrusion. Typically, different materials have unique requirements related to the generation of the specific properties. Following the requirements of this specification assures consistent characterization and valid comparisons of polypropylenes. This method provides a means to call out plastic materials for use in the manufacture of parts based on the material composition and specific physical/mechanical properties. End users, engineers, sellers, and buyers of polypropylene would in turn utilize the callout to specify a material for their particular application.

Specimen Preparation:
Specimen Preparation is based on classification of basic composition. Injection molding of test specimens is required for all tests outlined except heat stability testing.

Conditioning:
Controlled laboratory atmosphere is required. Individual methods outline specific guidelines as to time to test after molding.

Test Methods:
Testing outlined by the specification include Flow Rate (ASTM D1238), Density (ASTM D1505 or ASTM D792), Tensile (ASTM D638), Flexural Modulus (ASTM D790), Izod Impact (ASTM D256) Deflection Temperature (ASTM D648). Additional test methods are also called out.

Data:
Data is provided as outlined by specifications as called out by ASTM D4101. See individual methods for more information.
