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

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.
