This classification system covers reinforced and filled poly(phenylene sulfide) (PPS) materials suitable for injection molding and extrusion. This classification system is not intended for the selection of materials, but only as a means to call out plastic materials to be used for the manufacture of parts. The physical properties of the materials must meet the required tensile strength, flexural modulus, Izod impact strength, flexural strength, and density.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
Significance and Use
1.1 This classification system covers reinforced and filled poly(phenylene sulfide) materials suitable for injection molding and extrusion.
1.2 This classification system is not intended for the selection of materials, but only as a means to call out plastic materials to be used for the manufacture of parts. The selection of these materials shall be made by personnel with expertise in the plastics field where the environment, inherent properties of the materials, performance of the parts, part design, manufacturing process, and economics are considered.
1.3 The properties included in this classification system are those required to identify the compositions covered. If necessary, other requirements identifying particular characteristics important to specific applications shall be designated by using the suffixes given in Section 5 or Classification System D4000.
1.4 The values stated in SI units are to be regarded as the standard.
1.5 This precautionary statement pertains only to the test method portion of this classification system, Section 12. This standard does not purport to address all of 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—There is no known ISO equivalent to this standard.
