What is ISO 7313 about?
ISO 7313 discusses aircraft components. ISO 7313 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 ISO 7313 :
