1、Designation: D 5205 96 (Reapproved 2003)Standard Classification System forPolyetherimide (PEI) Materials1This standard is issued under the fixed designation D 5205; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last r
2、evision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 This classification system covers unfilled
3、, 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 materials is to
4、 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 to identify th
5、e compositions covered. There maybe other requirements necessary to identify particular charac-teristics important to specific applications. These may bespecified by using suffixes as described in Section 5.1.4 The values stated in SI units are to be regarded as thestandard.1.5 The following precaut
6、ionary caveat 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 pract
