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. Product Classification Hose assemblies are classified (type) (see Figure 1 for examples). Basic Performance (Using Roman Numerals) Each basic type is identified by performance in accordance with a military@ SAE@ or other industry specification(s) based upon pressure rating@ temperature rating@ and application(s).
