ASTM D6456-10

Standard Specification for Finished Parts Made from Polyimide Resin

SCOPE
1.1 This specification is intended to be a means of calling out finished plastic parts ready for industrial or consumer use.
1.2 This specification covers finished parts and shapes from which parts are machined, made from a semi-crystalline polyimide (PI).
1.3 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.
1.4 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).
1.5 Since PI is a thermoset resin, no provisions are included for recycled products.
1.6 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.
1.7 The values are stated in SI units and are regarded as standard in all property and dimensional tables. For reference purposes, inch-pound units are stated in parentheses.
1.8 Application—Parts in this specification are generally used for applications requiring the following combination of properties: low coefficient of friction, and low thermal expansion coupled with heat resistance for continuous operation at temperatures up to 260°C (500°F) and for short-term excursions upward to 482°C (900°F).
1.9 The following precautionary caveat pertains only to the test method portion, Section 12, of this specification:  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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
