This document specifies characteristics of hose assemblies with corrosionresistant 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: Nonconductive inner tube; and
