This SAE Aerospace Standard (AS) establishes type classification for those hose assemblies commonly used in aerospace fuel, lubricating oil, and hydraulic fluid systems.The purpose of this document is to create a common classification (type) system for the aforementioned hose assemblies. This is to facilitate determining comparability within a type, and offer a consolidated listing of active hose assembly types with performance references including fire resistance properties, and incorporate periodic fire testing of fire proof/resistant hose assemblies.
