Scope
This SAE Aerospace Standard (AS) covers batch qualification procedure for virgin and compounded polytetrafluoroethylene (PTFE) resins used for compression molding. AS9100 requires virgin and modified PTFE as a testing material be representative of production PTFE and/or parts. The testing specified herein is limited to tensile strength, elongation and specific gravity. Any other tests required by the purchaser must be specified separately.
Rationale
This standard provides a PTFE resin batch qualification procedure for tensile strength, elongation and specific gravity to ensure AS9100 compliance. AS9100 requires that any material specification shall be representative of production material and/or parts made from that material. Current ASTM specifications for qualification of batches of PTFE resins limit the qualification procedure, preventing such compliance.

Welcome to the AMS-P Polymeric & Composites Materials Committee discussion forum.
The AMS-P Polymeric Materials Committee writes and revises Aerospace Material Specifications (AMS), Metric Aerospace Materials Specifications (MAM), Aerospace Recommended Practices (ARP), and Aerospace Information Reports (AIR) for composite material technology as assigned to the committee.

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
