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.
