This document is applicable to empty-loaded changeover devices designed to automatically sense when the load of a railway vehicle reaches a defined value (changeover mass), which represents the point at which the vehicle is classed as "loaded" and thereby requires the brake force to be adjusted accordingly to achieve the required brake performance. This document also covers manually operated empty-loaded changeover devices and the associated changeover plates.

This document specifies the requirements for the design, dimensions, manufacture and testing of empty-loaded changeover devices.

This document applies variable load sensing devices designated to continuously sense the load of a railway vehicle and provide a signal that can be used by a relay valve for the automatic variation of the air pressure used for brake applications, thereby adjusting the brake force accordingly to achieve the required brake performance.

This document specifies the requirements for the design, dimensions, manufacture and testing of automatic variable load sensing devices.
