รายละเอียดเอกสาร

This specification is intended to be a means of calling out finished plastic parts ready for industrial or consumer use. This specification covers finished parts and shapes from which parts are machined, made from a semi-crystalline polyimide (PI). This specification is intended to replace MIL-R-46198 and Provisional Standard Specification PS 93. NOTE 1: There is no known ISO equivalent to this standard. This specification covers parts made from semi-crystalline polyimide, which is a thermosetting material that shows no softening or melting by DMA (D4065) at or below 260°C (500°F). Since PI is a thermoset resin, no provisions are included for recycled products. The classification system outlined in this specification is intended to be identical to that used by Department of Defense for over 20 years. No changes are intended at this time.
