This SAE Aerospace Standard (AS) defines the requirements for a threadless, flexible, self-bonding coupling assembly which, when installed on machined fixed cavity ferrules, provides a flexible connection for joining tubing and components in aircraft fuel, vent or other systems. This assembled coupling, hereafter referred to as the assembly, and is designed for use from -65 to +400 °F and at 125 psig nominal operating pressure.
Rationale:AS1650 Revision D returns vibration test to revision A test requirements. This revision encompasses changes to test specimen configurations, fixtures, fluid and vibration levels. Additionally, various changes were made to clarify proof and pressure surge test requirements.
