2、f last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope*1.1 This classification system co
3、vers unfilled, filled, andreinforced polyetherimide materials suitable for injectionmolding and extrusion.1.2 This classification system is not intended for the selec-tion of materials, but only as a means to call out plasticmaterials to be used for the manufacture of parts. The selectionof these ma
4、terials is to be made by personnel with expertise inthe plastics field where the environment, inherent properties ofthe materials, performance of the parts, part design, manufac-turing process, and economics are considered.1.3 The properties included in this classification system arethose required t
5、o identify the compositions covered. Otherrequirements necessary to identify particular characteristicsimportant to specialized applications are to be specified byusing suffixes as given in Section 5.1.4 Polyetherimide materials, being thermoplastic, are re-processable and recyclable. This classific

No other units of measurement are included in thisstandard.1.6 The following precautionary c
7、aveat pertains only to thetest methods portion, Section 12, of this classification system:This standard does not purport to address all of the safetyconcerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate safety andhealth practices and
