Product Code:SAE ARP594
Title:Fuel Pump Thermal Safety Design
Issuing Committee:Ae-5b Engine Related Components Airframe-Mounted Pumps
Scope: These recommendations cover only those design factors which might cause the pump motor or pump housing to act as an autogenous or spark-ignition source for explosive fuel vapors within the airplane tank. This Aerospace Recommended Practice (ARP) recommends fuel booster pump design requirements commensurate with the presently known state-of-the-art, relating to the prevention of autogenous ignition of explosive fuel vapors and the confinement of autogenous or spark-initiated flames by means of flame-suppressing devices.
