Aerospace. Lightweight polytetrafluoroethylene (PTFE) hose assemblies, classification 400°F/3000 psi (204°C/20684 kPa) and 204°C/21000 kPa (400°F/3046 psi). Procurement specification Ingestion-build-183511 11 and an end use1 Scope This International Standard specifies requirements for lightweight polytetrafluoroethylene (PTFE) hose assemblies for use in aircraft hydraulic systems at temperatures between 55 C and 204 C ( 65 F and 400 F), and at a nominal pressure up to 3 000 psi (20 684 kPa) or 21 000 kPa (3 046 psi). The hose assemblies are also suitable for use within the same temperature and pressure limitations in aircraft pneumatic systems where some gaseous
