This European Standard 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 European Standard also covers manually operated empty-loaded changeover devices and the associated changeover plates.
This European Standard specifies the requirements for the design, dimensions, manufacture and testing of empty-loaded changeover devices.
