SAE AS4720A – Batch Qualification Procedure for Tensile Strength, Elongation and Specific Gravity of Polytetrafluoroethylene (PTFE) Resins, Virgin, Modified, Pigmented and Filled Compounds Used for Compression Molding (Stabilized: Nov 2013)

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.
