SAE AS22759/50

The industry has identified fluoride off gassing as a potential serious issue in enclosed environments such as spacecraft and missiles. The evolution of fluoride gas can accelerate corrosions of metal surfaces and etching of optics. It can also accelerate copper oxidation. The industry has also identified additional aerospace critical tests since the legacy cross linked modified ETFE detailed specifications sheets were originated. These tests include wet arc propagation resistance, dry arc propagation resistance, dynamic cut through, scrape abrasion, UV laser marking and UV laser contrast after thermal aging and requirements have been included in this detailed specification sheet.
