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

Aéronefs — Tuyauterie flexible, haute température, convolutée, en polytétrafluoréthylène (PTFE)

A new edition is under development: ISO/CD 7313.

Abstract / 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.
