Language in which you want to receive the document.


This document applies to automatic variable load sensing devices designed to continuously sense the load of a railway vehicle and provide a pneumatic output 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, testing and quality assurance of automatic variable load sensing devices.
The requirements of this document are not fully applicable for tests on vehicle level (vehicle homologation tests).
