Bibliography

Applies to air spring control elements having to equip rail vehicles operating on a reserved track under permanent guidance without any distinction between the nature or the route of the track.

This standard specifies:

  • the characteristics the air brake control elements shall have and the tests to be carried out;

  • the guidelines for drafting the approval procedure applied by the customer;

  • the guidelines for drafting the qualification procedure for the product based on the requirements specified;

  • the guidelines for drafting the quality surveillance provisions for the manufacture of the air spring control elements.

The requirements of this standard are applicable to air spring control elements having to equip rail vehicles operating on a reserved track under permanent guidance without any distinction between the nature or the route of the track.

It covers complete control elements. It is essential that the various components are defined by particular specifications.

This standard specifies:

  • the differential valves;

  • the filters;

  • the levelling valves;

  • the non-return valves;

  • the minimum pressure valves;

  • the pressure-reducing valves;

  • the end stop valves;

  • the isolating valves.

This standard does not take into account the other air suspension control elements such as the installation of pipes, pipework elements and air production elements.
