Standard Classification System for Polyetherimide (PEI) 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 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.
1.3 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 specific applications. These may be specified by using suffixes as described in Section 5.
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 methods portion, Section 12, 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. Specific precautionary statements are given in Note 4.
