Standard Classification System and Basis for Specification for Polyetherimide (PEI) Molding and Extrusion Materials
ABSTRACT
This classification system covers unfilled, filled, and reinforced polyetherimide materials suitable for injection molding and extrusion. Unfilled polyetherimide materials are classified into groups according to their composition. These groups are subdivided into classes and grades. The plastic compositions shall be uniform and shall conform to the requirements specified. Determine the properties enumerated in this classification system using the referenced test methods.
SCOPE
1.1 This classification system covers unfilled, filled, and reinforced polyetherimide materials suitable for injection molding and extrusion.
1.2 The properties included in this classification system are those required to identify the compositions covered. Other requirements necessary to identify particular characteristics important to specialized applications are to be specified by using suffixes as given in Section 5.
1.3 This classification system and subsequent line callout (specification) are intended to provide 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 can be made by those having expertise in the plastic field only 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 costs involved, and the inherent properties of the material other than those covered by this standard.
1.4 This classification system allows for the use of recycled polyetherimide materials, provided that all specification requirements are met.
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
Note 1: There is no known ISO equivalent to this standard.
1.6 The following precautionary caveat pertains only to the test methods portion, Section 11, 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given at the end of 5.4.
1.7 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.

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 is to 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.
1.2 The properties included in this classification system are those required to identify the compositions covered. Other
