Product Code:SAE AS1710
Title:Coupling, Fuel, Flexible, Variable Cavity, Threaded Type With Ferrules
Issuing Committee:G-3, Aerospace Couplings, Fittings, Hose, Tubing Assemblies
Scope:This SAE Aerospace Standard (AS) defines the requirements for a threaded flexible coupling assembly, which utilizes ferrules or machined tube end fittings to join tubing and components in aircraft fuel and fuel vent or other systems. This coupling assembly is designed for use from -65 to +200 掳F and at 125 psig peak working pressure, and the coupling assembly may be used in other fluid systems when requirements are within the limits.【英文标准名称】:StandardTestMethodforFacingPropertiesofSandwichConstructionsbyLongBeamFlexure
