This International Standard specifies characteristics of hose assemblies with corrosion-resistant metallic braid and con-voluted polytetrafluoroethylene (PTFE) inner tube for use in air-craft fluid systems at temperatures between - 55 and + 200 °C and at nominal pressures, depending on bore size, up to 6,8 MPa. Special approval from the proper national authority may be required if these hoses are to be part of a pressurized gas storage system.
Svensk kommentar
I Sverige definieras nominellt tryck (nominal pressure): maximalt statiskt arbetstryck (?vertryck).
Swedish comment
In Sweden nominal pressure is defined as: maximum static working pressure.
Two types of hose assembly are covered in this International Standard:
Type 1: Non-conductive inner tube
Type 2: Conductive inner tube
