ASTM D4617

This classification system covers the different classes, filler types, and grades of phenolic compounds suitable for compression, transfer, or injection molding, or a combination thereof. It is intended to be a means of calling out plastic materials used in the fabrication of end items or parts, not for the selection of materials. The properties included here are those required to identify the compositions covered. There may be other requirements necessary to identify particular characteristics important to specialized applications, and shall be agreed upon between the user and the supplier. Sampled specimens shall be tested on and conform accordingly to the following physical property requirements: specific gravity; water absorption; Izod impact strength; flexural strength; deflection temperature; tensile strength; and compressive strength.

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.

1. Scope

1.1 This classification system covers phenolic compounds suitable for compression, transfer, or injection molding, or a combination thereof.

1.2 This classification system is intended to be a means of calling out plastic materials used in the fabrication of end items or parts. It is not intended for the selection of materials. Material selection should be made by those having expertise in the plastics field after careful consideration of the design and the performance required of the part, the environment to which it will be exposed, the fabrication process to be employed, the inherent properties of the material other than those covered by this classification system, and the economics.

1.3 The properties included in this classification system are those required to identify the compositions covered. There may be other requirements necessary to identify particular characteristics important to specialized applications. These will be agreed upon between the user and the supplier, by using the suffixes specified in Section5.

1.4 The values stated in SI units are to be regarded as the standard.

1.5 The following precautionary caveat pertains only to the test method portion, Section 13 of this classification system: 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—ISO 800-1992(E) is similar but not equivalent to this classification system. Product classification and characterization are not the same.
