DESCRIPTION

BS ISO 10502:2012


This standard BS ISO 10502:2012 Aerospace. Hose assemblies in polytetrafluoroethylene (PTFE) for use up to 232 °C and 10 500 kPa. Technical specifications and requirements is classified in these ICS categories:
  • 83.140.40 Hoses
  • 49.080 Aerospace fluid systems and components

This International Standard specifies requirements for polytetrafluoroethylene (PTFE) hose assemblies for use in aircraft hydraulic, fuel and lubricating oil systems at temperatures between −55 °C (−67 °F) and 232 °C (450 °F) for Class I assemblies and between −55 °C (−67 °F) and 135 °C (275 °F) for Class II assemblies, and at nominal pressures up to 10 500 kPa (1 523 psi) (105 bar1). The hose assemblies are also suitable for use within the same temperature and pressure limitations in aerospace pneumatic systems where some gaseous diffusion through the wall of the PTFE liner is tolerated.

This International Standard covers hose assemblies of the following classes:

  • class I: hose assemblies with fitting of corrosion-resistant steel or titanium parts [232 °C (450 °F)];

  • class II: hose assemblies with fitting of corrosion-resistant steel and aluminium parts [135 °C (275 °F)], DN12 and larger.

The hose assemblies specified in this International Standard are not intended for use in pneumatic storage systems. In addition, it is intended that installations in which the limits specified in this International Standard are exceeded, or in which the application is not covered specifically by this International Standard, for example for oxygen, be subject to the approval of the purchaser.
