Aerospace. Hose assemblies in polytetrafluoroethylene (PTFE) for use up to 232 °C and 10 500 kPa. Technical specifications and requirements1 Scope This International Standard specifies requirements for polytetrafluoroethylene (PTFE) hose assemblies for use in aircraft hydraulic, fuel and lubricating oil systems at temperatures between 55 C (67 F) and 232 C (450 F) for Class I assemblies and between 55 C (67 F) and 135 C (275 F) for Class II assemblies, and at nominal pressures up to 10 500 kPa (1 523 psi) (105 bar1). The hose assemblies are also suitable for use within the same
