ISO 7313:2020

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.
