Aircraft — High temperature convoluted hose assemblies in polytetrafluoroethylene (PTFE)

Scope

This document specifies characteristics of hose assemblies with corrosion‑resistant metallic braid and convoluted polytetrafluoroethylene (PTFE) inner tube for use in aircraft fluid systems at temperatures between ‑55 °C and +200 °C and at nominal pressures, depending on bore size, up to 6,8 MPa. Special approval from the proper national authority can be required if these hoses are to be part of a pressurized gas storage system.
Two types of hose assembly are covered in this document:
— Type 1: Non‑conductive inner tube; and
— Type 2: Conductive inner tube.
