This SAE Aerospace Standard (AS) establishes Type classification for those hose assemblies commonly used in aerospace fuel@ lubricating oil@ and hydraulic fluid systems. Purpose: 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@ offer a consolidated listing of active hose assembly types with performance references including fire resistance properties@ and incorporate periodic fire testing of fire proof esistant hose assemblies (see also Section 6).
