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.
